Shelf Life of Li-ion battery (Laptop)?

ms2000 1,315 32 January 5, 2016 at 07:26 PM
If I buy a Li-ion battery for my Laptop, what is the shelf life?

The one I have - I looked around for a date but never found one. I am wondering if I find a new one on a deal, where or not to buy it if the shelf life is good.

They often do somethings to the battery when they make it to allow for longer term storage before it's used, but I'd certainly avoid 'new' laptops that are more than 12-18 month old. EDIT: you're only talking about the battery, that gets hard, because after the model stops being made it often doesn't take that long before the battery stops being made. Best case scenario, the same model of battery was used in a bunch of models and was manufactured longer. At a certain point in a product life cycle, most of the batteries you can buy will often be re-manufactured by third parties.

Generally after the initial charge, if a battery isn't going to be used for an extended period it's best to store it with 70-80% charge and charge by the time it discharges to 50%. Which would mean plugging in a battery and charging it every 3-4 months in most cases. I try to plug in old cell phones about twice a year.

no absolute shelf life. voltage drop too low will hurt capacity.

the only thing you can do is if the seller guarantee any capacity even it marked as new, and return policy

some can use software to look at charge cycle and other info, the one you're using maybe can try software, i don't have a software to recommend

When u charge every 6 months, do u charge 100% or 70%?

70%. It's not good for lithium ion batteries to be held at 100% charge for any extended length of time.

it should be 70% and should probably be more often than every six months. Charging to 100% less frequently is ok, but not as good for the battery. With old cell phones, I just plug them in 2-3 times a year and charge to 100%. If the battery is currently >70% it gets skipped.

If my laptop is going to sit plugged in for an extended period I disable battery charging.
