Title: battery charger
Post by: Trumpkin on December 10, 2007, 02:03:01 PM
Okay so I found a universal AC adapter it says the current is 300mA and the voltages go from 1.5V to 12V. My battery is a 6v 2300mah Nimh. My Question is can I charge my battery with this? Can I just set it at 12v?

set it at ~8 volts

You can charge it , but itll take 2300 / 300 hours = around 8 hours for a full charge

there is no 8v but would 7.5v be okay?

yeah, but it'll probably take a bit longer

I'm very happy to say that I have started to charge my batteries and nothing has blown up (yet).
