1. Before storing discharge batteries and semi re-charge (half charge) (see instructions) –DO NOT FULLY CHARGE. Turn off the battery and unplug the charger.
2. Cool and dry storage at 5 ° C to 20 ° C.
3. Basically avoid prolonged disuse. In the case of long-term storage discharge the batteries and semi re-charge (half charge) them every six month.
4. Charge batteries fully before each use.
If you have stored the batteries over the summer months or a longer period without following above instructions, we recommend that you discharge and charge the batteries fully 3 times before the first use after storage.
To do that connect the battery to the sock / vest / bandage/glove or sole and discharge them using the highest setting. Then recharge fully to have the product ready for use.
