IDENTIFY BATTERY TYPE
Go to the store and buy a handful of batteries. The strangest thing is that most of the batteries are not marked with the type or chemical composition. So how do we identify these batteries?
Check the number on the battery and web search it. Sometimes the name only will find it. Most shelf batteries fall into one of several types. The types are typically listed below along with some common examples.
1) Alkaline - Energizer E95 (1.5V), Duracell
2) Zinc Carbon - Philips R20 LongLife (1.5V)
3) Manganese - Panasonic NEO R20NT (1.5V)
4) NiCd
5) Lithium Ion
6) Nickel Metal Hydride (NiMH) - Energizer Rechargeable
7) Mercury (obsolete)
8) Lead Acid (discontinued)
