To extend battery life and keep it at peak performance, do the following from time to time:
A) Keep the battery and all parts around it clean. The surface of the battery must always be dry, otherwise surface current leakage may develop, causing the battery to discharge.
b) The battery is maintenance-free and does not require technical inspection for the first 50,000 km or 4 years. Then a check every 30,000 km or every 2 years is necessary. During the cold season, do not store the battery uncharged as it will freeze.
When checking the battery with a load plug (voltmeter with parallel connected load resistor), the tool for 10 - 15 seconds on each element should show at least 1.6 V. If this value is less, this element may be discharged or damaged. The average cell voltage is 2 V. The voltage difference between the individual cells must be no more than 0.2 V. A damaged battery must be replaced.
Precautions.
When working on the electrical system, extra care must be taken not to damage the semiconductor devices (diodes and transistors) and avoid electric shock.
Always remove rings, watches, and other metal objects before working on the electrical system. Even with the battery disconnected, capacitive discharge may occur if the component's power clamp is accidentally shorted by a metal object. This may cause shock or severe burns.
Do not confuse the battery clamps. Components such as a generator, electronic controls or any other having a solid state circuit can be irreparably damaged.
When starting the engine using large wires and a starting device or a separate battery, you need to connect plus to plus and minus to minus. This also applies when connecting the battery to the charger.
Never disconnect battery, alternator, or any electrical wiring or instrumentation while the engine is running.
Do not allow the engine to rotate a generator that is disconnected from the electrical system.
Never test an alternator by shorting its output terminals to «mass».
When working on the electrical system, make sure the negative battery cable is disconnected.
Before using arc welding on a vehicle, disconnect the battery, alternator, and components such as the electronic ignition control and fuel injection system to protect them from damage.
