Battery Jargon: which is best?

[Adam Rook]

Which of these two batteries is best?

14.8 VOLT - 97 Wh
15 AMP - 93 Wh


I get the Watt Hours - that's a no brainer. But what's the difference in a battery with a 14.8 Volts and a 15 Amps?
I'm just confused by the AMP vs. VOLT specs

Volts and Amps are two different components of electricity. Think of it like water going through a pipe. Voltage is the pressure of the water, and Amperage is the flow rate of the water moving through the pipe.


First thing I'd check is whether the 93Wh battery also has a nominal voltage around 15 volts. That's the sweet spot for your camera (they will go as high as 16.8 and as low as 12.5-13V however)

I would also check if the 97Wh battery can sustain at least a 10A draw. That's so you can power your camera, plus all the stuff you could possibly plug into a DTAP/PTAP.

At that point, it comes down to cost/weight. IF the 97Wh battery is $50 or $100 more expensive than the 93Wh, then maybe the smaller one is the way to go. Conversely, if the 97Wh comes with built-in taps, or as a name brand (if that's important to you) then maybe go that route.
