The battery in my UPS (uninterruptible power supply) has just given up on me. With all the power cuts here, it's pretty much essential to power computers or video projectors etc via one of these.
I know you can purchase the complete unit in Fuerte but can you buy just the lead acid batteries anywhere?
eBay, make sure you don't touch any bare connectors inside before you disconnect the battery. We use ups and the risk assessment to work on then is considerable. The wee buggers bite ;)
