I use NiMH batteries, and have a great charger. It will charge almost any common size of NiMH or NiCad batteries. The problem is, it has two slots, and each holds two batteries. You can't use a compartment without two batteries in it. That means that I can't charge three batteries at a time. I propose
a Battery Blank, a device that is the shape of a battery and has the resistance of one. You would put it in in place of a battery, to complete the circuit and charge the other battery/batteries in the slot.

You should just get a better charger :-) |
|
| |
This was the best one I found. A lot of them will only accept 4 at a time. |
|
| |
Or you could connect the two poles of the emty slot with a bit of wire. |
|
| |
Hmm, maybe that would overload the first battery, I'm not really sure how NiMH batteries work. |
|
| |
Neither do I. But it seems to me battery number one is charged just as much as battery number two, three and four. It does not charge 1 and then 2 and so on, but all the batteries at the same time. Connecting the wire like I suggested might cause a bit of a strain when you have three empty slots and only one battery. But three batteries and one wire should work nicely. Or one battery and one wired slot. If you try it out and the thing gets hot very quickly, you can stop the experiment in time. |

Actually, there are two separate charger circuitries. Each circuit charges the batteries at the same time, and the circuit is on a timer. I figured this out with a continuity tester. Anyway, since it is measuring time, I think it might damage one battery. |
|
| |
Well, if you put it like that, [-----], I agree. Best not mess with it. |
|
| |
I can't find it, but wasn't there a related
idea here for a blank battery to use in
appliances, so that you could add or
remove one cell when switching
between NiCads and non-rechargables
(which have slightly different output
voltages)? |

There was. It was baked by “dummy batteries” and some built-in version of them, which are effectively just a wire. I don’t know if it’s a good idea to use them in a charger like this. Probably not. But I think [zero] is suggesting something which behaves like a battery in the charger, not just a wire. |
|
| |
Actually, it was I who suggested that, not [zeno]. |
|
| |
I said [zero], not [zeno]. Hmm, too close. Perhaps I’ll start using a different pronunciation. |
|
| |
Well, I wrote the idea, and his name is Zeno. Give credit where due. Look under the idea, my name is there. |
|
| |
I don't think you get it, [-----]. It was credited to [zero], which is how he/she pronounces your name. You were the one who brought up [zeno]. |

Earth to earth, live to live, ashes to
ashes. |

Ah. I feel really stupid. Shall I delete those posts? |
|
| |
No worries [-----]. I won’t be offended if you delete them (and this). BTW, I only call you that because that’s what it is in Morse code. |
|
| |
Ah. I just chose it to be anonymous, and (hopefully) mysterious. Also, my name causes some speculation in the annotations of my ideas. |
|

I had a piece of &*%^@#$ charger that was like this. It also took *FOREVER* to charge the batteries- I would put batteries in OVERNIGHT and when I woke up in the morning they STILL weren't fully charged?????? |

Is a battery load different to any other kind of electrical load ? |
