• Charge battery regularly. Observe instructions of the battery manufacturer.
Depending on the battery type, check the acid level before charging and refill each cell up to the marking using distil-
led water as necessary.
Modern starter batteries are typically maintenance-free.
Deep discharge will damage the battery and can render it unusable.
Keep battery clean and dry. Clean battery poles (+ and -) and terminals regularly and coat with acid-free and acid-
resistant grease. During assembly, ensure good contact of the terminal connections.
General limits for lead-acid batteries:
2.1 V / cell corresponds with full battery (charged).
1.95 V / cell corresponds with empty battery - recharge.
For a , the following applies:
- 11.7 V lower open-circuit voltage (battery empty), recharge battery.
- 12.6 V upper open-circuit voltage (full battery) - trickle charge full battery at 13.2 V.
For a , the following applies:
- 23.4 V lower open-circuit voltage (battery empty), recharge battery.
- 25.2 V upper open-circuit voltage (full battery) - trickle charge full battery at 26.4 V.
These values are based on a battery temperature of 20-25°C. Observe the instructions from the battery manufactu-
rer.
Note:
Fischer Panda recommends:
• Install battery circuit breaker and switch to OFF on the ma-
chine. (Cutting the battery circuit.)
• Secure the battery plus terminal close to the battery.
• Regularly check contacts for corrosion.
3.3.2 Measures for short downtimes
Short downtime (1 to 3 months)
• Measure battery charge status based on open-circuit voltage.
• During downtimes >7 days, disconnect battery (e.g. battery main switch to position 0).
• Check the battery within 2 months and allow the engine to warm up for min. 10 min.
3.3.3 Measures for medium term downtimes / hibernation
Medium term downtimes (3 to 6 months)
3.3.3.1 Surface protection measures:
• Check battery charge status and recharge regularly, roughly every 2 months, as necessary. Observe instructions
of the battery manufacturer.
• Check cooling water anti-freeze level and refill as necessary.
The anti-freeze agent must not be older than 2 years. The anti-freeze content shall be between 40 % and 60 % to
ensure corrosion protection of the cooling water circuit. Top off coolant if necessary.
If the cooling water is drained, e.g. after engine surface protection is applied, no water may remain inside the
engine during the downtime. The control unit must be marked accordingly with a note specifying "NO COOLING
