Nimh battery type question
Why is it that some device manuals (such as my Gameboy Advance among others)
indicate that I cannot use Nimh type batteries in my unit. Is this true, and will it ruin my gameboy, Walkman, Discman, GPS if I do indeed use Nimh type batteries in them? Thanks John |

Nimh and nicd's are 1.2 volts. However, trying them should't hurt the device. Ken |

NiCd and NiMH batteries are 1.25 volts under load; carbon-zinc alkaline batteries, 1.5 volts. No damage will result from using an NiCd or NiMH battery, but it will seem to be too weak and won't last long. If they say NiCd is OK but NiMH isn't, that's a much harder problem, since there is almost no electrical difference between them. The only device that should suit one and not the other is a charger, because NiMH has higher capacity and some NiCd chargers don't deliver enough power into them. |

A classic example occurred a few years ago with a major brand of underwater flash equipment. Their flash units at that time were not properly ventilated for NiMh cells and several exploded while being used with NiMh cells. There are also other differences between NiMh and alkaline cells besides the nominal voltage. Things like the discharge curves and the current rating. I own an RCA remote for entertainment centers that uses four AAA cells. I get far longer operation on a set of alkaline cells then I do with NiMh cells with this system. Unfortunate as I would rather not continue buying the alkaline cells. -- To reply no_ HPMarketing Corp. |

What about rechargeable alkalines? Worst of several worlds, from what I hear. |
