Measurement of NiMH Wh
« on: September 13, 2018, 06:48:48 PM »

I'm filling out a shipping form for an item that contains a 12 Volt NiMH battery. They want to know if there is a lithium ion battery, how much it weighs and what is the "watt hour measurement." I tried calling customer service at the manufacturer and didn't get anywhere so I'll try my luck here. I think (based on what I've seen on wikipedia) that NiMH are not using lithium as the metal. The weight of the battery cannot be guessed but regarding the "watt hour" measurement, does the 12V designation help to figure it out? If this question sounds absurd feel free to say so.

The datas should be written on the battery or in the discription of it. NiMH dont contain Lithium. It is Nickelmetalhydride. If you kow the max. current, then you can calculate W = U*I*t . Voltage times current  times time.

Scales or the documentation tell you the mass.

12V don't suffice to know the capacity. You have to check in the documentation. Or a specialist could measure it.

Absurd: not really, but the mass or capacity are asked prior to shipping because of fire risk by lithium and corresponding regulations, which is irrelevant with NiMH.
