recharging the battery
Bearing in mind these batteries are only a standby and not used in any routine situation.
The self discharge rate of these batteries is I believe 8% @ 21C and 15% per month at 40C. If we take 15% as a worst case. The maximum allowed charging rate for these cells is 1C ie. 65A, say for safety a max charging current of 30A has been selected by the designers that would require 20 mins per month of charging. Adjust the figures to the actual max charging rate.
I am confident enough time is spent hooked up to ground power to recharge these batteries.

Reason: added comma after 65A
