Interested in new 7.2V rechargeable batteries?

General

I have access to about a dozen NEW 7.2v 1100mAh rechargeable batteries that I can drop off at the HIVE if anyone is interested.

Just let me know…

Later!

What type of charger would they require?

Paul,

Something like this would probably be the ticket:

Chargers for the various battery types are pretty trivial to make. I would be more than happy to put one together for you while I am here if you don't do circuits at all. The parts are probably all in the space and if not debco will have them on the shelves.

I have no idea. A buddy pulls them out of access systems and replaces them with larger batteries. They have never been used and he asked if I know of anyone that can use them. Hopefully someone with more experience can chime in on NiMH charging options.

Ah, then you would want a ltc4060 circuit. The chip runs about $7 from digikey. But you can buy a universal nimh nicad charger for around $20 online.

I would take 2-3 for robotics :slight_smile:

I would also take a few, I can easily think of projects where those batteries would come in handy.

I dropped off 21 batteries at the HIVE yesterday, so everyone that indicated they wanted a few should be covered. (there are extras for people that might change their mind) They are in a small box on the tables where we have our Tuesday meetings. (wasn’t sure of a better place to leave them)

Enjoy!
