BATTERY MAINTENANCE
FOR BETTER FUNCTION AND A LONGER LIFE
STORAGE
CHARGING
• When storing for an extended period, the battery must be disconnected from the electrical system. Even very small currents (connected clocks, alarms, etc.) will discharge the battery and result in it
being damaged in the long term.
• Ensure that the battery is fully charged when it is stored away.
• Store the battery in a cool (frost-free) and dry location, as self-discharging is halved with every 10°C that the temperature drops.
• All batteries experience some self-discharge, which can be seen
from the drop in the open-circuit voltage. If the voltage drops below
12.4 V, the battery must be charged. Batteries that are not kept fully
charged are at risk of sulphating and losing capacity.
• Remember that a discharged battery can sustain freezing damage at
normal winter temperatures.
• Self-discharging in modern batteries is low, although batteries at rest
will nevertheless always slowly lose charge. This must be compensated for, either by charging the battery at certain intervals or with
continuous trickle charging.
A fully charged battery has open-circuit voltage:
A half-charged battery has open-circuit voltage:
A discharged battery has open-circuit voltage:
approx. 12.7 V
approx. 12.2 V
approx. 11.7 V
MAINTENANCE AND OPERATION
• Batteries must be securely installed and have good ventilation.
• Batteries work best at room temperature. Heat and cold conditions
impair the function of the battery.
• Keep terminals and cable terminals clean of deposits.
• Keep batteries clean and dry, as moisture and dirt can result small
currents (creep currents) in the lid and increase self-discharge.
• For batteries that can be opened, the electrolyte level (the acid)
should be checked regularly and if necessary adjusted with battery
water.
• Batteries should not be deeply discharged. Repeated deep discharges significantly shorten the life of the batteries.
