Beverly Tourer 250 i.e.
Sealed battery
If the vehicle is provided with a sealed battery, the only maintenance required is the check of its charge
and recharging, if necessary.
These operations should be carried out before delivering the vehicle, and on a six-month basis while
the vehicle is stored in open circuit.
Besides, upon pre-delivery it is therefore necessary to check the battery charge and recharge it, if
required, before storing the vehicle and, afterwards, every six months.
INSTRUCTIONS FOR THE RENEWAL RECHARGE AFTER OPEN-CIRCUIT STORAGE
1) Voltage check up
Before installing the battery on the vehicle, check the open circuit voltage with a regular tester.
- If voltage exceeds 12.60 V, the battery can be installed without any renewal recharge.
- If voltage is below 12.60 V, a renewal recharge is required as explained in 2).
2) Constant voltage battery charge mode
- Constant voltage charge equal to 14.40 ÷ 14.70V
-Initial charge voltage equal to 0.3 ÷ 0.5 for Nominal capacity
- Charge time:
10 to 12 h recommended
Minimum 6 h
Maximum 24 h
3) Constant current battery charge mode
- Charge current equal to 1/10 of the battery rated capacity
- Charge time: Maximum 5 h
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;
