Sealed batteries either come in kit form complete with acid pack, or are already factory sealed but still need charging.
Please specify when ordering if you would like the battery sent filled and charged or sent unopened. If sent unopened you must prepare the battery before first use.
It is VERY important not to use a conventional battery charger (not even a regular trickle charger) with sealed batteries, only chargers that state they are for sealed or MF (Maintenance free) batteries like the Optimate chargers are suitable.
