Dry-charge battery
COMMISSIONING A NEW DRY-CHARGED BATTERY
- Remove the battery air pipe stop cap and each single cell cap.
- Fill the battery with electrolyte of 1.270+/-0.01 kg/l density (corresponding to 31+/-1 Bé) with an am-
bient temperature not below 15°C, until it reaches the upper level indicated on the block.
- Tilt the battery slightly to remove any air bubbles formed during filling.
- Place the caps on each single cell filling hole without screwing them and leave the battery to rest.
During this stage, the battery is subjected to a gasification phenomenon and temperature increases.
- Let it rest until it reaches ambient temperature (this stage can take up to 60 minutes).
- Tilt the battery slightly to facilitate the elimination of any gas bubbles present inside; restore the level
using the same filling electrolyte
Note: This is the last time that electrolyte can be added. Future top-ups should be done only with distilled
water;
- Before 24 hours elapse, recharge the battery following these steps:
- Connect the battery charger terminals observing the correct polarity;
- Wit the battery charger drw. 020333Y and/or drw. 020334Y operate the battery charger control by
selecting the position corresponding to that capacity;
- Otherwise, charge the battery with direct current equal to 1/10 of rated capacity (e.g. for a battery with
a 9Ah rated capacity, the charging current should be 0.9-1.0A) for approximately a 4-6 hour charge.
Note: Batteries that have been stored for a long time may take a longer charging time. The battery
chargers drw. 020333Y and drw. 020334Y have an automatic protection which interrupts the recharge
after 12 hours to avoid battery harmful heating. In this case, a green LED turns on to indicate the
activation of the safety system and not the end of the charge.
- Let the open circuit battery rest for approximately 4-6 hours; then check the off-load voltage using a
standard tester.
- If the open-circuit voltage is higher or equal to 12.6V , the battery is charged adequately. Slightly shake
or tilt the battery to eliminate any air bubbles formed during recharging.
- Check the electrolyte levels again, fill them with distilled water up to the upper level line if necessary,
clean battery properly, close each single cell cap tightly and install it on the vehicle.
- If the voltage indicated is low, charge the battery another 4-6 hours in the way described above.
Note: With the battery charger drw. 020334Y, it is possible to check the battery charge level with the
Check function. The value indicated on the display must be higher than the value indicated on the chart;
otherwise, recharge the battery again in the same way indicated above.
