the vehicle when the battery is flat. If the vehicle does not have the special socket, an auxiliary battery
and/or a stabilised battery charger must be connected to the terminal poles on the vehicle's battery,
without using the battery master switch.
If the vehicle is not used for extended periods, remove the battery from the vehicle and recharge at least
once every 3 months.
If you intend to the leave battery connected to the electrical system, to keep certain connected devices
operating (car radio channel memory, alarm system, etc.), recharge at least once a month.
In case of doubt or if any signs of reduced battery performance are noted, check battery charge and/or check
the current absorption of the vehicle electrical system.
