Can NiMH and NiCd batteries use the same charger?
Can NiMH and NiCd batteries use the same charger?
I have a charger which was originally untended to charge NiCd batteries. I want to fully charge some of the NiHM batteries in my solar yard lights. While the solar charger normally charges them, it likely never gets them fully charged. I think they should be brought up to full charge at least a few times each year. If they need a special charger (made for NiHM), where can they be purchased? (Such as Walmart, Radio Shack, Hardware Stores, other local stores), since I prefer to avoid online shopping. |

(unless you're using a positron based battery system) It depends on what you are expecting from the charger and the lifetime you expect from the cells ("batteries"). A charger designed for NiCd's will typically *cook* a NiMH cell -- it just "doesn't know when to stop". Most (new) NiMH chargers can also handle the NiCd cell chemistry. A "dumb" charger (i.e., a resistor in series with a voltage source) will typically cook ANY battery (unless the voltage source happens to be lower than the cell voltage -- in which case, it simply won't COMPLETELY charge the cell). Some are timer controlled (they just "charge" for a fixed length of time and "hope for the best"). Obviously, you can see how reintroducing the battery tot he charger before the battery has "worked off" that previous charge will eventually result in the battery being increasingly (over)charged. Likewise, returning the battery to the charger after MORE than that amount of charge has been withdrawn means the battery will never be "topped off". "Smart" chargers are cheap. Buy one -- or five. |

A Nimh charger will charge nicads afely, but a nicad charger is not recommended for Nimh. |

Thanks. That is what I wanted to find out. I'll just get a NIMH charger for both types. Make sure you get one that says on it that it is for NiCd AND NiMh, or it likely will not be smart enough to not damage the NiCds. There are many available at most thrift shops if you don't like spending money. |
