what happens to overcharged batteries..

Here's a pix I took some time ago showing a pair of batteries that were overcharged. At work we have a temporary set of batteries we use to supplement the DC power when the tech's replace the control building's main battery set. The spare set is stored in at a remote site and left on charge. What happened is this: the temporary set is a series of 11 12volt batteries to make 132V DC. The charger is set at that float voltage. But, someone took a set of batteries out for whatever reason and never reset the charger. So..a set of batteries that should have been charged at about 108V was cooking at 132V. A few days later BOOM. A building alarm went off and this is what the tech's found... and battery acid over everything and acrid smoke. Moral of the story, pay attention to your charging system and batteries.

That was a bonehead move by someone. Glad no one was hurt.
