Macna Azra RTX Heated Glove kit - Black

. Batteries fit comfortably in the pockets within my Macna Azra RTX excellent gloves. Purchased as a back up pair of batteries when out on rides of more than around 3 hrs when set at the 2nd/3rd heat level. The original same model batteries do not appear to have degraded into the second winter season. In the real world expect around 90 mins at the highest power setting and around 4hrs at the lowest level (4th). Only downside is the charging period from flat of around 4hrs to fully charged but no big deal if you remember to recharge every time after a 4 plus hour ride. I’d recommend using the excellent blue tooth operated App to control the time periods on/off at different heat levels to optimise the battery usage. Very simple and quick to set.
