cura della batteria

A non-used battery discharges because of various leaks.

The speed of this process is very variable. It depends on the type of battery and temperature nella  Maintenance.

At standard temperature and humidity, a disconnected battery discharges at a rate of 1.2 % per day. With increasing temperature the discharge velocity increases: for example the discharge current is doubled in changing the temperature from 24 °C to 35°C. With cold this phenomenon is strongly reduced, being approximately null near the electrolytic solution freezing temperature. A good practice it is to recharge the battery every 20/40 days, avoiding, in this way, that the residual charge goes below 60/70 %, or worse, the so called sulfation process starts.

To take care of your battery you should keep its surface clean and to control the level of the electrolytic solution regularly.
If necessary, you can add a little demineralised water, but never sulphuric acid!

Batteries should be conserved in dry and temperature-controlled rooms. So they can be conserved without loosing performance up to 8 months.

If your vehicle is not used for a long time, the best practice it is to keep-off the battery, to re-charge and then conserve it in a cool and dry place. If the battery is left on, you should disconnect the negative terminal and control periodically the charge status.
