Note: These instructions are only recommendations. Always follow the battery manufacturer's instructions (often printed on a sticker on the side).
9. Charge the battery with 10% current of the battery capacity value (for example, if the battery has a capacity of 45 A/hour, the battery must be charged with a current of 4.5 A), checking the density regularly until no increase in density is observed for four hours.
10. Another way to charge the battery is with a current of 1.5 amperes, leaving it to charge overnight.
11. It is not recommended to use the fast charging mode with a high current for one or two hours, as this can cause irreparable damage to the battery plates.
12 When charging the battery, remember that the electrolyte temperature should not exceed 37.8°C.
