a) If left attached to a radio it is best to recharge the battery as soon as possible after use, but in any case no more than 7-days. Please re-charge every 7-days if stored un-used on the radio (we strongly recommend storing un-used batteries off the radio). b) For batteries left in storage off the radio, we recommend a monthly multi-meter voltage check to decide if they need topping up. If voltage drops below 7.0V, batteries should be recharged. Typically it takes it takes 3 months for a battery to self discharge from 8.0V to 7.0V. |
