A starter battery, also known as SLI (which stands for Starting, Lighting, and Ignition), is specifically designed to start combustion engines. They are used for automobiles, lorries, motorbikes, tractors, civil machinery, vessels, and aircrafts, among others.

The starter battery is designed to supply the starter motor with high electric current in a short space of time and to allow for depths of discharge (DOD) no higher than 10-20% (short cycle).

A particularly important feature is its capability to start a combustion engine at cold temperatures due to the fact that its capacity decreases when the temperature goes down.

Therefore, a starter battery must have the following characteristics:

  • High electric current supply, even at low temperatures.
  • Mechanical resistance to impacts and vibrations.
  • Operation within a wide temperature range (from –25 °C to +55 °C).

To carry out the restoration of this type of batteries, we recommend the following equipment:

Other additional equipment may be necessary and/or recommendable.
