Li-Ion batteries - shelf life?

[AndyStobbs]

As title, looking to buy a new battery for my disgnostic laptop. The laptop is an old HP NC6120 but works well. I want a genuine HP battery and now prices are lower than ever lately - still the same as a second hand laptop mind. So I think all these genuine batteries will be NOS, will that marr the performance.

lithium batteries are usually sold and stored with a storage charge, but there are alot of factors that come into play regarding a lithium chemistry battery as they are like a highly strung woman, and usually the daftest thing can set it off.
just buy one, use it for a week and if its crap, tell the seller and send it back.

I wrecked the battery in my laptop by using it on the charger, I thought it would reduce the cycling on the battery but all it did was reduce its capacity to about 30 seconds! So don't use your laptop on a charger let the battery run down the charge up from empty.

Good advise ^^^^^^^^^^^^ same goes for mobile phones constantly charged from car kits.

I have an old laptop I found while out walking last Christmas dumped in a hedge. It's never had a battery since I found it and works happily off a charger so if you use the lappy plugged in a lot just remove the battery

I have a li ion Makita impact screwdriver (the little flexi ones) which Sat for nearly 3 years and still had a full charge when I remembered I had it and needed it one day!

My diagnostic laptop is on mains gor 99% of the time, only use it on battery for the odd roadtest and stuff but the battery life is now sub 20 mins which is hopeless.
