It is important that the battery voltage is normal (approximately 12 V) when testing the car system components. If necessary a battery charger can be connected during the test.

Connect the battery charger to the battery terminals. Charge the battery for approximately 10 hours at the recommended current - maximum 6 A.

Example: If the battery is marked 520 A, the recommended charge current is 0.01x520 = 5.2 A.

A higher than recommended charge current may damage the battery.

NOTE: Boost charging (with a high current or voltage above 16 V) will damage the battery and is prohibited.

WARNING: Explosive oxyhydrogen accumulates when the battery charges. Smoking, welding, grinding or other activities involving sparks or naked flames are prohibited in the vicinity of a charging battery. Only charge the battery in a well ventilated area.
