For Christmas I bought the squaw a
bettery powered pair of gloves. She has something called Reynauds which causes blood in the extremities to be diverted to the core to preserve body temp when even a slight temp change happenes. This leaves the fingers and toes at a pretty high risk of long term damage. She can reach into the fridge to get a beer when it's 40 C outside and her fingers turn white.
Anyway, i got a nice set of li-ion powered gloves to help this winter. The warmth lasts about 1hr at the most on high. This is less than half of the claim. I want to get her some spare batteries but the ones from the MFR are $60 EACH. I see similar batteries (7.4 V, 2400 mAh) for as little $17 from battery outlets on the net. This size and power rating is common for Canon Camera batteries.
Questions:
1) can I go up in mAh safely (4800 mAh?) to provide a longer lasting battery without damage?
2) The OEM battery has a 3 stage controller on it, will I get the maximum from the battery if it's not got the controller?
Thanks for entertaining my cheap guy question.
