Most the batteries require regular re-conditioning which usually involves a light or a fan, a trickle charger and a lot of spare time.
I was under the impression that UPS use lead acid batteries as they don't require conditioning and discharging them fully is not a good idea at all as it will wreck the battery.
It depends on the particular battery. Some are specially designed for deep discharge cycles.
Aye, but you wouldn't put them into a UPS would you? The bigger UPS that I have worked with all used very large truck/lorry batteries, which as I understand it are designed to produce a large amount of power for a short time (i.e. to get the engine started) so using them in a UPS was for the same reasons (i.e. you want lots of power for a very short amount of time so you could either turn all your computers off or have your diesel generator kick in).
