How to charge Group 94R (H7, L4, LN4) battery?
Charging Group 94R/H7 batteries is typically handled by the vehicle’s alternator or charge controller when connected to the car’s electrical system.
However, if the battery needs to be charged off the vehicle, using an intelligent AGM battery charger is recommended. Look for one that supports various battery chemistries (wet/flooded, AGM, Gel-cell), offers multiple charging modes (including desulfation and cell-equalization), temperature compensation, and other similar features.
After fully recharging the battery, a good charger will automatically switch to maintenance mode to keep the battery topped up over time.
For 75-80 Ah lead-acid batteries, an optimal charging current is around 10 Amps. This current level efficiently recharges the battery without overloading it.
There are numerous battery chargers available on the market, with the NOCO Genius 10 being recognized as one of the top models.
