I did something stupid a while ago, and didn't find out about it until last night. I've had my laptop plugged into a non-surge protected powerstrip. Both batteries (including the one I bought 2 months ago) are now toast.
My car battery is also toast. At least, that is the conclusion I arrived at because my car will only start with the battery charger hooked up. Fortunately, it is still under warranty, so I took it back to NTB. The guy was mumbling about it looking fine under the tester, and under pressure admitted that it was leaking from the posts. They had no replacements in stock, come back next week.
Whatever, things aren't all bad.
