rechargeable battery tester?
battery tester December 19th, 2009Can I use a 1.5V battery tester to read 1.2V rechargeable batteries?
Yes. These types of tester typically put a small load on the battery under test. A rechargable NiCD or NiMH battery will be fully charged at 1.4 volts and discharged at 1.0 volts. A rechargable battery will show a higher voltage with no load than it will actually have under load. Using a regular voltmeter or multimeter in this situation will show a higher voltage than the battery has. Almost any battery will show good with a multimeter or voltmeter.

Using 1.2 V rechargeable batteries will have no effect on the use of your device. Indeed, an alkaline battery only benefits from 1.5 V voltage at the beginning of its discharge. Then, it drops constantly well below 1.2 V. Finally, it drops to around 0.6 V. Most equipment will work happily on anything between 0.9 V and 1.5 V. Unlike alkaline batteries where the voltage drops quickly, rechargeable batteries offer a more constant voltage.
