Comment on New nickel-iron battery charges in seconds, survives 12,000 cycles
cmnybo@discuss.tchncs.de 2 weeks 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.
This is theoretically something sodium batteries would be good at right?
Aren’t they not as sensitive to storage voltages? They are almost a perfect lead-acid replacement. Plus a UPS is a great usecase because it doesn’t matter if it is 33% bigger to achieve the same capacity.

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.

They’re also trustworthy, reliable technology. Why change what isn’t broken?

It’s brand new, I’m reading directly from the instructions, if it only takes 30min to change they should say that and it’s not by design.

It makes sense to me to have low power chargers on a UPS. Once your power comes back online, it needs to deliver enough juice to power everything plugged into the UPS plus the battery charger. A fast charger would be more likely to trip a breaker.
