It is the formation of lead sulfate crystals on the battery's internal plates. Small crystals normally appear during use, but when the battery stays discharged or unused for a long time, those crystals grow and harden. This reduces battery capacity and, in advanced cases, can no longer be reversed even by fully charging the battery.

On average, depending on use, climate and maintenance, the service life of a battery is:

• Car: 3 years
• Work vehicles: 1.5 years
• Recreational vehicles: 1 year

Some warning signs: the engine takes longer to start or cranks slowly when you turn the key, the lights look dimmer than usual, the battery is 4 years old or more, or you frequently need a jump start.

The main cause is battery sulfation. Other common causes include leaving lights or accessories on, an alternator that no longer charges properly, dirty or loose terminal connections, an old battery that no longer holds a charge, or the power the vehicle itself draws while parked (clock, alarm, electronic modules) when it isn't used for several days.

BATTSAVER is a smart solar-powered technology that protects your vehicle's battery by offsetting its natural loss of charge. It helps prevent sulfation, extends service life and reduces the need for premature replacement, helping cut the generation of polluting waste.

It captures the sun's energy and converts it into a stable, controlled charge sent to your vehicle's battery to prevent discharge and improve performance.

BATTSAVER is designed for cars, work vehicles, recreational vehicles, boats and sailboats.

By maintaining charge and helping prevent sulfation with 100% solar energy, BATTSAVER can extend the service life of batteries in cars, SUVs, ATVs, boats and buggies up to 7 years. In work vehicles such as trucks and agricultural or industrial machinery, it can double service life, depending on the battery's condition and operating conditions.
