To prevent this, use a charger with a three-stage charge controller, which stops overcharging and manages self-discharge after the battery is fully charged. Battery Undercharging Undercharging can result in sulfation and reduced battery life. Ensure the battery is fully charged after use and topped off every few weeks if stored for a long period.
With the CCCV method, lead acid batteries are charged in three stages, which are constant-current charge, topping charge and float charge. The constant-current
