Features of charging and maintenance
Even a new battery requires proper maintenance to maintain its life. Regular checking of the electrolyte level (if the battery is serviceable) and charge density is a mandatory procedure. During winter, it is recommended to remove the battery and store it in a warm room, recharging it every 2-3 weeks.
For charging, use special chargers with an automatic shutdown mode. Manual charging requires constant monitoring of the voltage and temperature of the battery case. Overheating during charging can cause permanent damage to the plates and reduce capacity.
How to properly check the density of the electrolyte?
A hydrometer is used to check density. In each jar it is necessary to select the electrolyte and look at the float readings. Normal density is 1.27 g/cm³ for a fully charged battery. If the density is below 1.20 g/cm³, charging is required.
Particular attention should be paid to the condition of the terminals and contacts. Oxidation leads to an increase in contact resistance, which causes a voltage drop and difficult starting. Regular cleaning of the terminals with a wire brush and lubrication with a special compound will prevent these problems.
- Once every six months
- Once a year
- Only in case of problems
- Never checked
