Battery
Refer to specific instructions and warnings accompanying your battery. If this information is not available, observe the following
precautions when handling a battery.
!
WARNING
Recharging a weak battery in the boat, or using jumper cables and a booster battery to start the engine, can cause serious
injury or product damage from fire or explosion. Remove the battery from the boat and recharge in a ventilated area away
from sparks or flames.
!
WARNING
An operating or charging battery produces gas that can ignite and explode, spraying out sulfuric acid, which can cause
severe burns. Ventilate the area around the battery and wear protective equipment when handling or servicing batteries.
Auxiliary Batteries
Mercury strongly recommends using at least group 27 or 31 type AGM batteries when load shedding devices are used in place
of auxiliary batteries. Boats using JPS are typically large vessels with many DC loads and the minimum group 24 batteries will
not be sufficient.
The use of a load shedding type device is also applicable in place of an auxiliary house battery or when connecting house
loads to the starting battery.
