"37 Watts lithium ion battery" is meaningless as a capacity. As is "10,000 milliamps per hour". You likely have a 10 amp hour, 3.7 volt battery yielding a cap

"37 Watts lithium ion battery" is meaningless as a capacity.
As is "10,000 milliamps per hour".
You likely have a 10 amp hour, 3.7 volt battery yielding a capacity of 37 watt hours. This is about the same capacity as an ordinary smart-phone (perhaps a bit larger, I think an iphone is 5 or 10ish ).
- dfuego 12y ago10,000 mah is the same as 10 amp hour. And that is 6 times what an iPhone has actually
- amalcon 12y agoThose units are very different from milliamps per hour (which is basically a nonsense unit) and watts (which are a unit of energy per time, therefore saying nothing about how long the battery will last). I'm just trying to address the confusion here. Battery capacity is a relatively mundane detail, and I don't necessarily expect the people writing marketing copy to understand electrical terminology.
- noonespecial 12y agoYeah iphones are pretty small. I seem to remember some of my Sammys and Motos having in the 9-12 range. 37 might actually be approaching some small netbooks. The capacity for energy storage is volts * amps over time. So a 10 amp hour battery at 3.7v holds less energy than a 10 amp hour battery at 12v. Together it makes watt-hours. That's the best way to measure storage capacity.
