3.4 BATTERY
The following battery has been installed in your Alstor at the factory:
822: Silver Dynamic C6, 552401052 SD 12 V/52 AH Varta 520 A(EN)
834: Europart Plus 12 V/72 AH, 572409068.EP, 680 A(EN).
850/850 H: Europart Plus 12 V/72 AH, 9561572409. 680A (EN)
Care and maintenance
Make sure the battery and space around it is clean and free of dirt. Moisture and dirt around the battery terminals cause creepage currents.
Keep the terminals clean from oxide and dirt; no grease on the terminals.
The battery is so-called maintenance-free (according to the EN standard) and under normal conditions lling uid (water) is not required.
Battery localisation
1. Detach the oor plate next to the operator’s seat (model 822/834).
2. Tilt the cab according to the separate instructions (for model 850/850 H).
Battery replacement
Loosen the cable lug from the minus terminal of the battery rst, then the positive terminal and the battery bracket.
When reinstalling the battery and cover, connect the minus cable lug last to avoid sparking.
Also, make sure that the battery seat and cable lugs are clean (if necessary, replace with new ones) and that the cable
lugsandthebatteryare secure.
WARNING! Batteries produce explosive hydrogen gas during charging. Sparks or an open ame can give rise to explosions
with arisk of serious injury. Always use protective clothing and face protection. Leave battery maintenance work to an
experienced mechanic.
Keep the following in mind
If the machine is going to be put in storage for along period of time (3 months), the battery should be recharged beforehand.
Afully charged battery can cope at –63°C. Afully discharged battery can only cope down to –4°C.
It is best to store the battery under cold temperatures, since the self-discharge rate increases as the temperature increases.
Abattery left with an o-load voltage of 12.4 Vshould be charged (the fully charged o-load voltage is 12.7 V)
If the battery has discharged to alevel where the machine does not start, an old-type charger (not voltage-regulated)
should be used. Aso-called automatic/smart charger will not always fully charge adischarged battery.
When using abooster cable, connect the + terminal rst. To prevent an explosion, earth the – cable to the chassis, not the battery.
