I have a battery charger which only fits AA and AAA batteries. I recently bought a Maglight flashlight, which uses three D cells. I want to put rechargable batteries in it, but I have no way of charging them, unless I buy another (expensive) charger. It seems that almost all battery chargers these days are only for the AA and AAA batteries. There are only a few that charge the C and D cells, and they are 4 or 5 times the price of the AA/AAA ones.
I'm wondering if I can charge the D cells using my AA charger. I have several D sized battery holders on hand. I'm thinking of attaching some wires to the battery holders and just using some alligator clips to clip to the AA charger contacts. (Making sure the polarity is correct).
Physically this is easy. But I wonder if the battery charger will work properly on the D cells. Both the D and AA batteries are 1.5 volts, but the D cells have a higher current capability.
The higher current makes me think that the charging time will be longer, which is no problem. But I am posting this to inquire whether there are other reasons to NOT do this? For example, will it damage the charger?
Comments, anyone????
