How to care for your L19L3PF4 battery.

This is the Replacement lenovo L19L3PF4 Battery, You can extend the life of your L19L3PF4 battery significantly through the proper care and handling of your battery.

• Any new L19L3PF4 battery should first be fully charged by leaving it plugged in overnight. Once a computer battery is fully charged it will no longer accept any more power. It is a common practice to leave laptops plugged in after they have been turned off so that the battery has a full charge the next time you use your laptop. It is probably fully charged within 5 hours.
• A brand new L19L3PF4 laptop battery is in a weakened condition since it has not been conditioned yet. Condition and break in your new battery by performing 5 partial discharge and recharge cycles the first week you receive your new battery.
• Run on battery power without the AC adapter cord at least once a week to keep the L19L3PF4 battery cells active and at their peak potential. When your laptop is plugged into the power adapter the battery goes to ‘standby mode’ while your laptop runs directly on electricity from the wall outlet.
• Even though your battery indicates it is fully charged, your battery will return to a weakened state again in a few months if it does not get some exercise through partial discharge and recharge cycles while running on battery power alone.
• If your L19L3PF4 battery has not been actively used 2 months or more, condition your battery again with 5 partial discharge & recharge cycles to increase the batteries capacity and run time.
• Don’t run your battery all the way to empty. Your battery will have a longer service life if it receives shallow discharge and recharge cycles. Research has shown that the useful life of the battery will be much longer if you begin to recharge the battery any time before reaching 20% of the remaining power capacity. Recharging the L19L3PF4 battery even after 10 minutes will not reduce the battery’s life span as lithium batteries do not have the memory effect which was found in older NiCad battery technology. NiCad batteries have never been used in laptops, even the earliest models.
• Never run your battery below the 2% critically low warning point. If your battery is run below this point it may not have enough energy to even recharge. This may effectively ‘kill’ your L19L3PF4 battery.

How can I extend your battery run time?

You can extend your L19L3PF4 battery run time by minimizing the power drain on your battery. A 3 cell battery will run approximately 2 to 2-1/2 hours when the battery is new. Even longer times can be achieved by minimizing the power consumption of your laptop. Here are the top ways to reduce your power consumption.

• Avoid using the CD or DVD drive as the motor consumes a fair amount of power.
• Turn off your wireless finder if you are not using the internet.
• Remove any devices plugged into your USB ports or other ports.
• Close out programs you are not using. By minimizing the load on your CPU, sometimes you can avoid having the cooling fan turn to its high speed mode.
• Increase your memory to 4 Gigabytes. This creates less work for your hard drive. Data is temporarily written to your hard drive when your memory is not sufficient to hold all the data on the many pages you may be accessing.
• Reduce the brightness of your laptop screen. This is the number one drain on your battery by far.

How can I extend your battery run time?

You can extend your U13 battery run time by minimizing the power drain on your battery. A 3 cell battery will run approximately 2 to 2-1/2 hours when the battery is new. Even longer times can be achieved by minimizing the power consumption of your laptop. Here are the top ways to reduce your power consumption.

• Avoid using the CD or DVD drive as the motor consumes a fair amount of power.
• Turn off your wireless finder if you are not using the internet.
• Remove any devices plugged into your USB ports or other ports.
• Close out programs you are not using. By minimizing the load on your CPU, sometimes you can avoid having the cooling fan turn to its high speed mode.
• Increase your memory to 4 Gigabytes. This creates less work for your hard drive. Data is temporarily written to your hard drive when your memory is not sufficient to hold all the data on the many pages you may be accessing.
• Reduce the brightness of your laptop screen. This is the number one drain on your battery by far.

Google’s plan to limit data tracking on its Chrome browser has been extended to cover apps on its Android-based smartphones.

Its so-called Privacy Sandbox project aims to curb the amount of user data that advertisers can gather.

Rival Apple now forces app developers to ask permission from users before tracking them.

The news will be a blow to firms like Meta, which rely on putting their code on apps to track consumer behaviour.

Meta said this month that Apple’s changes would cost it $10bn (£7.3bn) this year. Google’s Android operating system is used by about 85% of smartphone owners worldwide.

No detail
Third-party cookies, which use people’s browsing history to target adverts, will be phased out on Google’s Chrome browser by 2023.

In a blog, Google said it was now extending what it calls its Privacy Sandbox to Android apps, and working on solutions that will limit sharing users’ data and “operate without cross app identifiers, including advertising ID”.

These identifiers are tied to smartphones and are used by apps to collect information. Google said that it will keep them in place for at least two years, while it works “with the industry” on a new system.

“We’re also exploring technologies that reduce the potential for covert data collection, including safer ways for apps to integrate with advertising SDK (software developer kits),” it added.

The tech giant did not detail how it plans to do this.

Apple decided in April last year that app developers had to explicitly ask for permission from users to use IDFA (Identifier for Advertisers). Data from advertising company Flurry Analytics, and published by Apple, suggests that US users are choosing to opt out of tracking 96% of the time.

Google’s blog did not name Apple, but referred instead to “other platforms” which it said “have taken a different approach to ads privacy, bluntly restricting existing technologies used by developers and advertisers”.

“We believe that – without first providing a privacy-preserving alternative path – such approaches can be ineffective,” it added.

Google, unlike Apple, relies on advertising revenue.

Google’s attempts to create alternatives to third party cookies on its Chrome browser have not gone entirely smoothly.

Its first proposal -a system called Federated Learning of Cohorts (Floc) – was disliked by privacy campaigners and advertisers alike.

Floc aimed to disguise users’ individual identities by assigning them to a group with similar browsing histories.

Real-time bidding
Its successor, Topics, was announced recently and aims instead to group users in topic clusters selected out of about 350 categories such as fitness or travel. When someone visits a website, Topics will show the site and its advertising partners three of their interests from the previous three weeks.

The Competitions Market Authority has been scrutinising Google’s transition to more privacy-focused systems and said of its plans to extend them to Android apps: “We will continue to monitor this closely and engage with Google on the nature and detail of its proposals.”

The average app includes at least six third-party trackers that are there solely to collect and share online data, according to a report commissioned by Apple last year.

And any one data broker is estimated to have data on up to 700 million consumers, according to research firm Cracked Lab.

Regulators, such as the UK’s Information Commissioner’s Office, are investigating the advertising ecosystem, especially the way ads are sold – known as real-time bidding – which automatically places billions of online adverts on web pages and apps every day.

Apple plans to introduce a number of changes to make it harder to misuse AirTags to track someone.

The button-sized devices are designed to work with Apple’s ‘Find My’ network to locate lost items.

The company said its changes to the device will make suspicious tags easier to find, and alert users earlier that an AirTag may be travelling with them.

In January, a number of women told the BBC they had been followed using AirTags.

Apple launched AirTags in April last year. The small, circular devices can be attached to luggage or keys – anything you could lose.

But the devices can be misused to track people by being hidden in a car, or on a personal item such as a bag.

As part of the changes to make misuse harder, Apple said every user setting up their AirTag for the first time will see a message warning that using the device to track people without consent is a crime in many regions around the world.

Currently, iPhone users (and Android users who download an app) receive “unwanted tracking” alerts if an unknown AirTag moves with them.

Apple announced that people will be alerted earlier that an unknown AirTag is travelling with them.

And when people are warned of “unwanted tracking” by an AirTag, users of iPhone 11, iPhone 12, and iPhone 13 devices will be able to use “precision finding”, to see the distance and direction to an unknown AirTag when it is in range. Previously only the owner of the AirTag could do this.

More noise
Currently iOS users can send an unwanted tracking alert to make the suspect AirTag play tones and Apple has said tags will use louder tones in the future to make the tag easier to locate.

The company said it will also add to a feature that makes an AirTag that hasn’t been with the person who registered it for an extended period of time, play a sound when moved.

In theory this could reveal the presence of an AirTag to a stalking victim, but recent reports revealed that AirTags with the internal speakers deactivated had been listed for sale online.

To counter this, when the sound is triggered and the AirTag is detected moving with an iPhone, iPad, or iPod touch, an alert will also appear on that device.

Apple also said it will also update its support article on unwanted tracking with additional information and resources.

Apple AirTags are incredibly good at finding things. They can track your items down to 0.1 feet.

But that accuracy means that, in the wrong hands, they can be used as sophisticated tracking tools.

This isn’t theoretical, as the BBC reported last month, there’s evidence that people are using AirTags to follow people.

The AirTags themselves are relatively new, and it’s clear that Apple hasn’t yet worked out how best to protect people.

For example, it took six months after AirTag’s launch for the company to bring out an app that would alert Android users to an unwanted AirTag.

The new updates that Apple plans to come out later this year – precision finding and AirTags that emit louder noises – are what campaigners have been calling for.

But with these iterative updates, there will be questions over whether Apple launched the product too early.

Apple said it designed “products to provide a great experience, but also with safety and privacy in mind”, adding that it was “committed to listening to feedback and innovating to make improvements that continue to guard against unwanted tracking”.

It also noted that “based on our knowledge and on discussions with law enforcement, incidents of AirTag misuse are rare; however, each instance is one too many”.

Batteries fuel modern life, from smartphones to electric cars. But how do they store electricity and why don’t they last long enough? And, as Samsung might be asking itself, why do they blow up?

Battery life is an explosive issue. Literally, as Samsung is discovering to its dismay. The company’s Galaxy Note 7 smartphone was praised upon release for best-in-class battery life, far outpacing its key competitor, the iPhones 6S and 7 Plus. Then it started blowing up. Samsung issued a recall and replace programme, and the replacements also started blowing up, forcing the company to suspend production entirely.

The affair marks the latest road block on the long fight to improve the batteries that power our electronics. While processing speed doubles around every 18 months, battery capacity takes almost a decade to improve to the same degree. That gap is starting to cause problems, but as Samsung has found to its cost, it’s not easy to fix.

A smartphone often lasts less than a day, a laptop sometimes only a few hours and an electric car struggles to go 350 miles. So why is it that battery life is still such a problem – and when are we going to fix it?

What is a battery?

Batteries are small containers of chemical energy. When a smartphone is plugged into the mains, electricity is used to reset a chemical reaction within the battery, transferring electrons from the negative anode to the cathode – the positive end of the battery.

Once charged, the battery can then create electricity by driving electrons through a circuit, in this case a smartphone, to the anode and will continue to do so until all of the electrons contained within the battery have transferred to the anode or a built-in switch disconnects the battery.

What is a battery made of?

Inside a typical battery you have an anode, a cathode and electrolyte – something for the positive ions to travel through.

Lithium-ion batteries found in most smartphones and electronics have a metal oxide cathode made of a cobalt, nickel, manganese or iron mix, a porous graphite anode that holds lithium ions within it and a lithium salt electrolyte.

Positively charged lithium ions travel through the electrolyte from the anode to the cathode driving electrons through the smartphone as required and back to the anode.

Why doesn’t it last long enough?

The principle of the battery may be simple, but the chemistry and technology to make it work is not. The major limiting factor for batteries is their energy density.

A battery can only generate as much electricity as its chemical components can store energy. Everything that is not the active material within the battery is effectively dead weight, including the casing, the controller chips, the wires to carry the current out – they all add weight but not power.

A typical lithium ion battery within a smartphone has an energy density around 150 Watt-hours per kilogram (Wh/kg). While Lithium ion battery energy density has improved since its introduction in the early 1990s, it is held back by its construction and chemistry.

The only way to immediately increase a smartphone’s battery life with current technology is to increase the power efficiency of the smartphone’s electronics and increase the size of the battery – but thinner and thinner smartphones demand thinner and thinner batteries.

Why does battery life diminish?

Battery life doesn’t stay constant for the entire life of a smartphone – it diminishes slowly over time, as the battery is discharged and recharged.

This is because the chemical reaction that produces the electricity causes thin layers of lithium to be laid down on the electrodes, which reduces the amount available to generate electricity and increases the internal resistance of the battery.

The higher the resistance the harder the battery has to work to maintain a usable voltage and so the amount of power it can produce per charge decreases. You might remember this bit from school:

Voltage = Current x Resistance (V=IR)

Why do some batteries explode?

Batteries with much higher energy density than lithium-based cells are already available, but they aren’t safe enough for use in portable electronics.

“The more energy you put into a box, the more dangerous it’s going to be,” says Dr Billy Wu, lecturer at Imperial College London’s Dyson School of Design Engineering. “Safety is absolutely key and thermal management is crucial. If a battery heats up beyond 80C you hit what is called thermal runaway, where the components start to decompose, and that’s when it can explode.”

The specific cause of Samsung’s issues with exploding batteries is unknown, the company just cites “a battery cell issue”.

What happens next?

In the immediate term, battery advances will come by bringing existing lithium-ion technologies closer to their theoretical limits, which will increase the power density of batteries.

A typical lithium-ion battery using lithium manganese oxide has a theoretical power density of 280 Wh/kg, but the final product only has 150Wh/kg so there is certainly room for improvement.

“It’s about optimising the structure within the battery,” says Wu. “If you imagine inside your battery you have this porous structure full of the active material.”

“For higher power output, you need a more porous structure to increase the surface area and allow more lithium ions through at any one time, but because it’s got more holes it holds less active material, which in turn gives you lower capacity.”

New, advanced battery chemistries such as lithium-sulphur and lithium-silicon are also being worked on, with companies around the UK currently developing the technology.What is the future of battery technology?Solid state batteries are one possible future, where the liquid electrolyte in the battery is replaced by a solid substance, which will provide significant safety improvements.
Advertisement“The main advantage of solid state batteries is that you can go back to using lithium as the anode material, which has really good power and energy density, but wasn’t safe with liquid electrolytes,” explains Wu.
Solid-state batteries will remove the need for the porous carbon anode and therefore removes more of the weight from the battery that doesn’t contribute to generating power.
Metal air batteries, using zinc, lithium or aluminium are also on the horizon, but are 20 years away from being available in a commercial application according to Wu.
What can I do to help my battery last longer?There are a few things you can do to help prolong the life of your battery. The nature of the chemical reaction inside the battery means that it has to work harder in the last 20% of discharge and above 80% of charging.
Keeping a lithium ion battery roughly between 80% and 20% of charge will help it keep a greater amount of its capacity for longer. Smart power management systems are currently being developed that do just that when plugged into a wall overnight.
Batteries should never be left constantly plugged in, which is particularly applicable to laptops. They are kept in better working order if they are discharged and recharged every so often. Once a month should do it.
