Battery care and storage (Chevrolet Aveo T300)

At least once every two weeks, remove dust and dirt from the surface of the monoblock and battery cover with a dry cloth. If electrolyte accidentally appears on the cover, remove it with a clean rag soaked in a 10% solution of ammonia or soda. Then wipe the surface of the cover dry.

To prevent oxidation of battery terminals and wire tips, clean them regularly and lubricate them with petroleum jelly. Make sure that the wire tips and terminals are tightly connected.

Periodically check the reliability of the battery mount on the car and tighten it if necessary to avoid cracks in the monoblock.

The lead-acid battery must be stored only in a charged state. At temperatures below -20°C, the battery must be charged once a year for 48 hours with a constant voltage of 2.275 V per cell, and at room temperature - once every 8 months for 6-12 hours with a constant voltage of 2.35 V per cell. Storing the battery at temperatures above 30°C is not recommended.

A layer of dirt and scale on the surface of the battery becomes a conductor for current from one contact to another and leads to self-discharge of the battery, after which premature sulfation of the plates begins. This is why the surface of the battery cover must be kept clean (wash before storing). Storing lead-acid batteries in a discharged state leads to a rapid loss of their functionality.

When storing the battery for a long time and discharging it with high currents (in starter mode) or when the capacity decreases, it is necessary to carry out control and training ("therapeutic") cycles, that is, discharge-charge with the nominal current.
