6 FAQs about [9vdc battery and solar charger]

Can a battery charger charge a 9v battery?

Most chargers are compatible with AA and AAA batteries. If you want to charge 9V, C or D-size batteries, check carefully for a model that can. Charge indicator Some battery chargers have lights to indicate when batteries are charged.

How to charge a solar battery?

Place your solar battery charger in a sunny location. A southern facing window would be perfect. Connect your battery to your solar charger. Wait about 45 - 60 minutes (remember this charger is slow.) Disconnect your battery and recheck the voltage of the battery.

How much charge can a 9V NiMH battery hold?

Now my 9V NiMh batteries have only 300 mah of charge, meaning the max I can throw at them is 30 ma. As most cells you find online are at least 50 ma of current we're going to have to find a better solution.

How many volts is a trickle solar charger?

This solar charger we are building is a trickle charger rated at: 12 volts - 1 Watt - .083 amps - this guy is slow, but unless you're using 9 volts a lot (few people do these days) it'll do the trick just fine for our needs. To learn more about connecting multiple solar panels (and what wiring in series means) I recommend this video.

How do you connect a solar panel to a battery?

Using small bits of wire I connected the cells together. If you have a multimeter you can always give them a test when you're done. Lastly we need to add the diode and battery connector. The reason we use a blocking diode is to prevent the solar panels from trying to suck power back out of the batteries at night.

How do you connect a solar battery to a diode?

First wrap the positive (red) wire from the battery connecter to the black stripped side of the diode. It's important that you connect the battery connector to the BLACK STRIP side of the diode otherwise you'll end up blocking power coming from he solar cells. Then solder.
