Dry battery activation
Remove the vent plugs and fill each battery cell with sulfuric acid with a density of 1.27-1.28 Kg/l
(1.23 Kg/l for tropical countries) up to the acid level mark and never more than 15 mm above the
top of the plates. Wait about 30 minutes for the level to settle and then top up where necessary.
Connect the positive battery terminal to the positive charger terminal and negative battery terminal
to the negative charger terminal. It's recommended to use a charging current of 10% of the Ah
capacity of the battery (e.g. 44Ah battery = 4,4 A charging current) till 16 V tension.
Replace the vent plugs. When the charge is finished, at room temperature and not working,
the battery should has a tension between 12.7 V and 12.9 V.
Wet battery recharging
Batteries must only be recharged using continuous current (max 16 V). Connect the positive
battery terminal to the positive charger terminal and negative battery terminal to the negative
charger terminal. It's recommended to use a charging current of 10% of the Ah capacity of the
battery (e.g. 44Ah battery = 4,4 A charging current) till 16 V tension. When the charge is finished,
at room temperature and not working, the battery should has a tension between 12.7 V and 12.9 V.
For more than 4 months in stock it's necessary use a special charger able to do charge and discharge cycles.
Wet batteries storage
Store in dry and cool environment (frost free), at room temperature not higher than 25°C, sheltered from sunbeams, powder and weather conditions.
The batteries can be stacked one of the top of the other only if terminal and lids are sheltered and gas can circulate freely. Wet batteries gradually discharge during
storage: that's why the batteries should be so arranged that they can be properly rotated with respect to date of manufacture (FIFO storage system). Metal shelves
with anti-acid paint are recommended. Batteries storage depend by temperature: check regularly the terminal voltage: it has to be more than 12.8 V; on the
contrary the battery needs to be recharged.Wet batteries that have been in stock for 6 months are considered "over age".
Dry batteries storage
Dry batteries need the same storage conditions as wet batteries but for longer time (12 months).
Installing the battery
Check that the tension of the new battery is 12.8 V. Check the capacity requested by the vehicle. Check the driving belt, the alternator and the starter because often
they are directly concerned with bad working batteries. Switch off the engine, fill the battery in its compartment and connect the terminals.
Ensure that the clips are secured.
Batteries contain sulfuric acid (corrosive) and give off an explosive gas especially during charging process.
To avoid problems is better:
• Handle with caution
• Wear gloves and eyes protection
• Always charge in a well airy place
• Avoid sparking, smoking and flames when handling batteries
• Avoid direct contact between battery terminals
• If acid splashes over the skin or into the eyes rinse immediately with a lot of water
• If acid is swallowed drink water or milk; in every case contact a doctor immediately
• Small spillages can be washed away with water
do not throw away
