I am on my 3rd or 4th 25$ 9 cell 'high capacity' laptop battery from Amazon.
When they are near useless i have been harvesting the cells, discarding the 1 or 2 which can't maintain voltage overnight, and using them in a flashlight.
The last battery pack, all the cells hold 4.2 volts for weeks, but they are essentially useless as they have so little capacity and cannot support any significant load.
I am back to cycling my panasonic NCR 18650b instead as that Way, I don't waste time swapping out batteries, and have the full brightness levels accessible.
My current laptop battery is about 4 months old and can last about 50 minutes and I am already getting the weak battery shop now for replacement messages.
I like to tinker but I would not attempt replacing the cells myself, not without a spotwelder for the tabs, and likely not even then.
If I could get a battery pack with 9 3400 mah panasonic cells i bet it would last for 5 hours.
