how many aa batteries equal a pound
0.81 ounces (23g) AA batteries can be made using several different chemical makeups. While 23g is a good approximation for an alkaline AA it's not a good guess for NiMH or Li Fe2S. The L91 Energizer AA only weighs 14.5g. A good battery manufacturer will have datasheets on their website that will include the weight.
There are many different types of batteries: Tiny coin batteries, as in hearing aids, can weigh just 2 to 5 grams AA batteries can weigh from 15 g (lithium) to 31 g (Nickel metal hydride rechargeable). Size D flashlight batteries can weigh from 110 g (lithium) to 175 g (NiMH rechargeable) Wet Cell batteries for cars and boats normally weigh several kilograms.
