I have a 4 year old UPS, and I just opened the battery cover to take a look at the battery, as it is probably time to replace the battery. It looks like some electrolyte is leaking around the edges of the battery. Since it is a sealed lead acid battery, that is probably sulfuric acid (and maybe even some lead?). Do you think it'd be safe to try to handle the battery and remove it, or should I just discard the UPS altogether and get a new one? Getting a new battery would cost only $30, but getting a new UPS with the same specs would cost around $170-$200.
