question for the experts, I have an electric razor that runs off of two rechargable AA size low capacity ni-cad cells wired in series and charged with a wallwart. these are toast. If I replace them with two AA high capacity NIMH cells can I charge them with the same wallwart? cheers Roy. |
| seadog:
Probably not. They charge at different rates. There are chargers that can adapt to different cells but a cheap wall wart will not be in that category. |

If the NIMH cells are of a higher Amp-Hour rating then you'll certainly be safe - it will just take longer to fully charge them. Phil |

So far one against and one for. And I'm no better off. :bang: Anyone else have any input? Cheers Roy. |
| seadog:
I'll add to what Philf said. It may take longer to charge or you may not achieve a full charge. It probably wouldn't cost very much to buy a Nimh rated supply from that well-known auction site. I changed the cell in a Dremel copy that I have, from Nimh to LiIon and bought a cheapo charger. I don't think it cost me more than £10 and I also got a spare cell for that price. |
