  I’ve heard about the Storage mode in the MultiPlus-II battery charger in regard to lead acid batteries. Can you explain what it does and why it’s important for battery maintenance?

  The Storage mode in the MultiPlus-II is a battery-preserving feature.

  When your battery hasn’t been used for a day, this mode kicks in to lower the float voltage. This helps prevent damage to the battery that can happen if it’s just sitting there, like corrosion or gassing.

  And once a week, it boosts the voltage back up to keep the battery in good shape.

  The Storage mode in the MultiPlus-II is a specialized function designed to reduce battery degradation during periods of inactivity.

  When a battery has not experienced any discharge for 24 hours, the Storage mode activates, reducing the float voltage to 2.2V per cell (e.g., 13.2V for a 12V battery).

  This reduced voltage minimizes gassing and corrosion of the battery’s positive plates. Periodically, once a week, the system raises the voltage to the absorption level, a process known as ‘equalization’. This equalization is crucial to prevent stratification of the electrolyte and sulfation, which are major factors in early battery failure.

  By managing the battery voltage in this manner, the Storage mode effectively prolongs the battery’s health and operational lifespan.
