Reviving lithium battery

[givenall]

Does anyone one know about a program that revives notebook battery. I Remember Compaq used to offer with their business notebook few years back.

Thanks in advance

Don't waste your time with those snake oil apps that supposedly revive your battery. If the laptop battery don't hold a good charge anymore and the battery adapter/charger is OK, then it's just time to buy a new battery. Most laptop batteries will start heading south at around the 2 year point...how far they make it pass that 2 year point depends on various factors such as quality of the battery, how your normally used the laptop such as mostly plugged in all the time and the charge staying at 100%....a lithium ion battery staying at full charge most of the time is determintal to the lifespan of the battery. Not uncommon for quality laptop batteries to maintain good charge capacity past 2 years of age...go to 3 or 4 years maybe...also not uncommon for many not to make it even to the 2 year point.

All most battery apps will do is just completely discharge the battery and then let it fully charge. Heck you can do that by just letting the laptop run down to say 1 to 3% charge level and then start charging it again. And that process has nothing to do with "reviving" the battery as it just re-calibrates the laptop's charge indicator.

As a quick but short-term solution you can freeze the battery.

There are numerous discussions on the topic. Search "reviving lithium battery in freezer."

But for duration, strength and reliability it would be better to simply buy a new battery.

Myth: Store batteries in the refrigerator

False. Storing a battery in the refrigerator or freezer is not only bad, but can be dangerous. Extreme temperatures - hot or cold and especially for long periods of time - are not good for any type of battery.

Remember, a battery is a collection of chemicals that store energy. Doing something that upsets those chemicals can have dangerous consequences.

To maximize shelf life, Energizer suggests storing "batteries at normal room temperatures (68 degrees F to 78 degrees F or 20 degrees C to 25 degrees C) with moderate humidity levels (35 to 65 percent RH)." This should provide a shelf life of five to 10 years for your standard, cylindrical alkaline cells and 10 to 15 years for cylindrical lithium batteries.

By the way, if you're wondering why your smartphone battery isn't performing as well after just a year or two, that's because the more you use a battery, the less efficient it becomes.

Never heard of reviving Lithium batteries , only NiCad because of their memory effect.

My computer battery is 9,5 years now and still has about 30 % , just enough to take over for when the awful Thai mains glitches or just black outs.

Just go on Google Play as there are dozens upon dozens of apps that will fix/revive a lithium battery (giggle, giggle)...expect there are PC versions also. Heck some apps will even use a display similar to the Windows Drive Defrag program as if the app is evaluating/repairing every little bit within a battery. Snake oil at its finest. But snake oil sellers seem to have pretty good sales volume...always have.

This ‘battery repair’ Android app has been downloaded over 1 million times… and it’s a total fraud
