I used to have a exide orbital in my stereo car back in the day. Loved that thing, it could go down to 6 volts, i would smash 16v-17v when charging it.

Lasted 4 years going strong, then i put it in retirement in the shed somewhere.

Never had any issues with it, well worth the coin i payed for it. Only thing wrong with it, is that it that weighed a lot and was a very large battery.

These days i just use Cat batteries, but i am biased as i get them discounted.
