Charge your new battery when it arrives and is first used. If you are buying a spare or it's not being used for long periods then it will also need recharging every eight weeks to keep the cells in good order for future use.
If it stays on a charger for long periods for convenience then it might be a good idea to allow an almost full discharge every couple of months to help condition the battery.
