3.5.1 Reference note for the starter battery at a long-term standstill
Notice:
Starter batteries
Self-discharge of batteries is a physical and chemical
process and cannot even be avoid by disconnecting the
battery.
• Disconnect the battery from the generator at a long-term standstill.
• Charge the battery on a regular basis. Follow the notes of the battery manufacturer.
Before charging the battery, check the acid level according to the type of battery and refill each cell with distilled
water up to the marking if necessary.
Today’s starter batteries are normally maintenance-free.
Deep discharge may damage the battery and may be useless afterwards.
Keep the battery clean and dry. Continuously clean the battery terminals (+ and -) and clamps and lubricate with an
acid-free and acid-resistant grease. Make sure there is a good contact of the clamp connections when assembling. If
voltage is approx. below 1,95 Volt, the cell should not decline the open-circuit voltage of the battery. This equates
approx. 2,1V / cell open-circuit voltage when battery is fully charged.
For a 12 V battery applies 11,7 V lower open-circuit voltage (battery flat) - conservation charging 13,2 V.
For a 24 V battery applies 23,4 V lower open-circuit voltage (battery flat) - conservation charging 26,4 V.
These data relate to a battery temperature of 20-25°C. Consider the specifications of the battery manufacturer.
Notice:
Fischer Panda recommendation:
• Install a battery main switch and turn it to the off-position.
(Disrupt the battery circuit)
• Install a sufficient fuse in the positive battery line close to the
battery
• Check contacts for corrosion on a regular basis.
3.5.2 Arrangements at a short-term standstill
Short-term standstill (1 to 3 months)
• Measure the charge of battery via the open-circuit voltage
• At stand still >7 days - disconnect the battery (e.g. put battery main switch to 0)
• Drain the waterlock. Disconnect the exhaust line between waterlock and generator. Close the exhaust line of the
generator.
• Within 2-3 months - let the engine run for at least 10 min
• Fill fuel tank to 100% (level to full).
3.5.3 Arrangements at a medium-term standstill / winter storage
Medium-term stand still (3 to 6 months)
3.5.3.1 Arrangements for conservation:
• Check the charge of battery and recharge approximately every 3 months if necessary. Consider the specifications
of the battery manufacturer.
