Second generation of iPhone. Model A1241 / 8 or 16 GB capacity / black or white plastic back. Repair is more straightforward than the first iPhone. requires screwdrivers, prying, and suction tools.

Can use old iPhone batteries for solar charge?

Hi

I have like 30 used iphone 3g batteries that i have replaced fom old iPhones, i wondering if i can get some use for them connecting on series/parallel to a regulated solar panel.

My goal its to use a 12 volt system and run 3 10w led lights overnight whit 4 10w solar panels.

Thank you.

Remember that you are talking smart batteries here ;-) You will have to definitely design a circuit with the proper charging parameters as well as proper connectors. Check at Batteryuniversity.com for more info on the batteries.
