I have some post cap type solar lights that came with Ni-MH AA 400mAh batteries that don't hold much of a charge. Lights go out in a few hours. I have some Ni-CD 1000mAh batteries that I was wondering if they would work in the lights. Am not sure if "charging circuit" in lights will work on either type.
Added for clarity: The main question is switching from Ni-Mh to Ni-Cd? Will the charging circuit work?This message has been edited. Last edited by: gjgalligan,

I read somewhere that these barely charge the batteries and you do not want to use larger mAH batteries in them. Not sure the science there, but give it a shot and see what happens.

Added real batteries to my post cap solar lights after the original ones died.
They didn't actually die, but were mostly cosmetic. The 1600mAh batteries stay on all night and I haven't had any problems (leaking, thermal runaway, etc...) with them. Plus they stay on all night.

I have a charger (120v, plug in the wall outlet) that has separate modes for each type.
