There's more to this concern about the battery capacity. I also bought and tested a number of heated glove models and learned that the insulation of the glove will make all the difference and ensure that whatever battery power available it is used efficiently by the gloves. If the gloves cannot keep your hands fairly warm without running the heat, then the batteries are going to die quickly during use.
^^QFT. And in addition with a well insulated electric glove, if you forget to charge the batteries or one or both run out of power before the day is over, then you still have a reasonably warm glove on your hands.
One solution is to use a heated liner with no insulation and then wear it inside a insulated glove. Likely the most cost effective way if one already owns the appropriate insulated over- glove.
Huge +1 to both of these posts - this is the best-kept secret in the heated glove industry.
I recently tried the OR Capstone and found it puts out a lot of heat but does not contain it as well as I hoped on cold days. When I turned it on indoors, I could feel heat radiating on the outside the glove -- not a good sign for energy conservation. On my next very cold ski day, I ran a different test:
On my left hand, I wore the OR Capstone. On my right hand, I wore an OR Stormtracker inside an OR Alti (shell + mitten liner). The Capstone puts out more immediate heat, but after a minute the Stormtracker + Alti wins easily at any given setting.
For a fairer setup, I tried the OR Capstone inside an OR Alti Shell (no liner) against the same OR Stormtracker + Alti Mitt (shell + mitten liner) configuration. Stormtracker/Alti setup still won after a minute or two. I ran the same experiment inside and found what I expected: the Stormtracker/Alti leaked much less overall heat than the Capstone + Alti shell. I'm sticking with the Stormtracker/Alti and returning the Capstone.
(If you're wondering why I didn't try the OR Capstone + full Alti mitt configuration; the Capstone is too large to fit in the Alti liner).
There are certainly downsides to this setup -- very little dexterity (but enough to hold a ski pole), and it requires a manual battery swap if you want as much runtime at a given setting (Capstone holds two batteries). But for less money than just the Capstone glove, I have a warmer and much better insulated setup, and if I need fine finger movements, I can briefly remove the Alti while keeping the Stormtracker on (which is much more dextrous than the Capstone; I was pleasantly surprised to find I can do a complete battery swap without taking the gloves off).
