11.4.3 Battery: Instructions for recharging
– A battery is fully charged if at constant temperature the density of the electrolyte and the measured
voltageatthepolesdoesnotincreasedwithin2hours.
– Eachrechargewill be goodasgood are thegeneralconditions of thebattery.Thismeans thatanold
battery,aftercharging,willnothavethesamelifeandefficiencyofanewbattery.
– Thesimplestchargingmethodistochargeatconstantpower.
– At the end of the charging, the battery charger voltage increases and creates gasification. It is

– For old batteries (in most cases sulfated) charge with great caution. Even with 13.8 Volts there is the
possibilityofatemperatureincrease.
Follow these instructions to recharge the battery:
1. Disconnectthecablesofthevehiclefromthebatterytoprotecttheelectricalsystemofthevehicle.
2. Placethebatteryatasafedistancefromthevehicle.
3. Ifpossible,removethecaps.
4. Checktheelectrolytelevel,ifpossible.
5. Cleanthepoles.
6. Makesuretheroomissufficientlyventilated.
7. Limitthechargingcurrenttoamaximumof1/10ofthebatterycapacity(Ah).
8. Connectthebatterytothecharger.
9. Connectthechargertothemains.
