If you had about 30 or 40 12v 7.2A Lead Acid batteries what could you do with them?


I am wondering if I should get these, they are free, so it;s more of a matter of wasting storage space and being unable to get -rid- of them if I can't use them for something practical. I've been meaning to make a little follower-bot, so I may have a use for about 6 of them at most...Any suggestions before I go and pick em up?

If there's a market for em, that's good, they're all relatively in good repair; they were used for power supply backups for modem/routers, so they were kept in constant charge. If selling them will net even a mild profit, scrapping or otherwise, I suppose it'll be a good investment(seeing as they're free). Would it be a good idea to discharge them for holding purposes, or will that damage them more than help? I'm not exactly an expert on batteries.

1. Where would you store them - 30 or 40 take up a big area.

2. If they are not maintained and regularly charged in a few months they will be scrap - Or are they scrap now?

3. You could make up a battery pack and build an electric car.

4. Sell them Lead acid batteries are expensive and have a value even as scrap.

Yeah, I seem to have discovered #2 the hard way -- I had a "chump starter" (gel-cell battery in a box to be used as an emergency jump-start for a car) and after being ignored for a couple years it no longer holds a charge. Haven't gotten around to repairing it.

Are they new, used or old?

If new then they run about 15$ to 45$ depending where you buy them.

The 7.2A - is that amp-hours, how big are these?
Lead is worth ~1$ per pound at the moment.
