- I would bet that the charger you saw was for standard carbon-zinc cells.
- The carbon-zinc batteries can be recharged somewhat, but they won't work
- terribly well afterward and you can only get one or two rechargings out
- of them. Rechargers for these batteries were quite popular back before
- NiCds and alkaline cells came out.
-
- If you charge an alkaline battery, your chances of rupturing it are
- pretty good. I've never seen one literally explode, but I have seen
- them split down the side and spray causic goo around. Don't do it. It's
- not worth it.
