What is the weight of an alkaline battery?

Average Life and Weight of a Watch Battery?

• Talking about "Silver Oxide" batteries. Disregarding recharge ability, how long does a normal watch battery (of decent-good quality) last? Also, how much do they weigh? Doing some math and need a precise weight for each one please. Thanks :D

• Answer:

  Of course the answer depends on what the battery is to be used for, or rather in which type of watch. A watch battery used in a a conventional analogue only watch will last around 2 years. If the same watch battery is being used in a watch which has alarm functions and a back-light then this will depend on how much each function is used. Back-lights in particular will drain the battery a lot quicker if used excessively. There are two variants of many of the silver oxide batteries, low drain and high drain, the latter being recommended for higher drain devices such as those watches with the functions described above. The source below gives the cross reference information to a lot of the watch batteries available,but also, if you click more information on the chemistry heading, you will get the capacity of some of them in mAh. The higher the capacity the longer the battery will last given the same drain as a lower capacity battery. I am not sure where you will find the weight of the battery from. The difference between them is probably fractions of grammes, not something which concerns many watch wearers.
