Comment on New nickel-iron battery charges in seconds, survives 12,000 cycles
cmnybo@discuss.tchncs.de 2 hours agoUPS batteries need to be fully charged all the time. Lead acid batteries like to be fully charged. Lithium batteries need to be stored around 50% charge to have a long lifetime.

Lead batteries are also cheap.
And mine take ~30 minutes to charge. This person may want to replace their batteries.

Charge time depends on the UPS. The cheap consumer grade ones usually have a float charger that takes forever.
