Hello folks,
Please excuse what is probably a silly question, but I would rather ask silly questions than catch something on fire.....
My wife has recenty purchased 5 sets of solar powered garden lights.
These work fine when fully charged, but the UK winter does not give enough light to charge the small internal batteries.
I was looking to connect the internal batteries ( 1.4V dc, 1000mAh, AA size ) to a small power supply to trickle charge them during the day & night.
I think that connecting them in parallel should give me a capacity of 5000mAh, so a charge of 500mA shouldnt cause any problems.
I want to leave in the current solar panels, as there is a light sensor built in to switch them off in the daytime, and I was looking to keep that.
I have a number of assorted low voltage power supplies with outputs of around 500mA.
Can I just wire the batteries together in parallel and feed them from one of these ?
I can put am ammeter in the circuit to make sure I'm not pulling more than 400 - 600 mA
I am sure there are lots of better ways to do this with circuits and transisters etc, but I'm afraid my skill level with electronics is limited to a miss spent youth bodging car electrics back together and fixing children's toys
Many thanks for your help.
Andy
