Battery Solar Charger

I am fed up with constantly buying batterys while I am camping and so I bought a solar powered battery charger. the only problem is that it does not charger 9v cells. can any one recommend a way of constructing one.
At present, I have a 12V...

disregard Johann, he doesn't know that transformers work only on AC.

Probably voltage output is too low to charge a 9 volt battery.

You can buy another charger, or add a DC-DC converter to boost the 3 volts to 9 volts.

I haven't bought one yet just collecting...

Its likely that you battery may just need to be replaced. Your battery should always start unless its been two months or more. If you battery was dead for a long period of time it may have sulfated in which case it will probably be cheapest to...

I have got a solar power trickle charger for car battery but the thing is, there are no indications to prove that it is working and the battery is charging. The shop says they haven't got any electrcian to test the darn thing.

I would

use a multimeter...or at a push an low powerd LED.

I want to get a solar battery charger to keep my campers battery maintained while on camping weekends. The place we go is wooded and the collector panel will most likely be often shaded. Will it still work? will pick best answer.

I would not say very well. Solar means it needs sunshine and about 8 to 10 hours. Can you extend the wire and place the panel up high or out further into the sun. We have solar fence chargers and they work 21 days without sun when fully charged....
