Batteries – a source of electrical energy required to produce a spark when the engine plant, or in those rare cases, not when your generator does not produce sufficient power. Its principle is simple: Electrical energy is generated by a chemical reaction of two reagents, with the possibility of repeated recharging. When the battery is charged it to sit on the external circuit, while the reaction products recovered starting materials. The new or fully charged battery electrolyte density should be 1.24 g / cm in the summer and 1.28 g / cm in the winter. Do not forget that when the electrolyte level drops, there might be 2 reasons: 1) if the electrolyte is spilled, it is necessary to replenish the electrolyte, 2) if boiled away – it is better to add distilled water. For safety, never allow a strong reduction of the electrolyte in the battery, because under the covers cans accumulate a mixture of oxygen and hydrogen, which is extremely explosive and can be ignited by the slightest spark, and it is dangerous. Nor can we strongly supercool battery, while inside active material of electrodes formed ice crystals, which are squeezing it out of the lattices, and it crumbles at the bottom of the battery.

Also be that the battery is completely discharged. If the battery does not charge for a long time, then to restore its performance will be. Causes a complete discharge may be operating with a faulty electrical (starter, alternator, etc.) or a long parking lot with lights on, tape, etc. To long time not to buy a new battery must be periodically cleaned of its upper surface, grease the pole of the battery with petroleum jelly, pull the wires on the terminals of the battery. The average lifetime for its correct maintenance for 5 years.
