Charging NimH batteries while in a device.
Ok, to start out, I have no idea what I'm doing. Now that' I've gotten
that out of the way, here is the plan. I just got a remote control called the OneForAll Kameleon. It's an awesome remote with one problem, it's batteries die in 1-2 weeks because of it's backlight feature which automatically turns on whenever you think about touching the controller. I don't want to give it up however, so I am going to see if I can mod it. It takes 3 AAA batteries and I am planning on putting rechargeables inside. I then will then cut into it slightly and add metal contacts which link inside of the remote to the battery poles. I'm going to build a cradle for it that has matching contacts to deliver a charge (think cordless phone). Using 3 1.2V NiMHs with 700ma capacity I know I want to be charging at 70ma. I plan on just leaving the controller there whenever I'm not using the entertainment center. Ok, here is where I point out my total lack of knowledge. I only can find AC to 4.5V DC adapters that output at 700ma, this seems like a bit much (I'm thinking exploding batteries). I know I need to knock it down to 70ma, I just don't know how. Please help me, and feel free to just make fun of me for being an idiot too. Thanks, -Fritz |
