For people who are looking for smart technology, and advanced battery chargers that work quickly without much effort, then this unit may be the perfect answer.

For 12-volt charging requirements, the BatteryMINDer 12248 is an ideal choice. It has several safety features that make it user-friendly, and it will not overcharge a battery.

It can charge any 12-volt battery, including dry-sealed and wet varieties. It will charge any number of vehicles and equipment, including motorcycles and boats.


BatteryMINDer 12248 Main Features


  • Low-Amp Charge
  • Safety
  • Several Battery Styles
  • 3-Stage Charge
  • Desulphator


Low-Amp Charge


When a battery is charged at a low amp rate, it can help to prolong the life of the battery. Users can select from 2, 4 or 8 amps to charge the battery, as well as a trickle charge setting.

It will keep your batteries on a steady charge, even when you don’t need them, and they are not in use. Whether it’s for a sump pump backup (when the power goes out in a rainstorm,) or for your motorcycle that you only ride once a month, the BatteryMINDer 12248 will not let you down.




The unit comes with several safety measures in place, which protects both the user and the battery. Overcharge protection and reverse-polarity protection are the two key safety features of the BatteryMINDer 12248.

If the polarity is reversed, the unit emits a red light indicator, and charging will not start until the polarity is correct.


Several Battery Styles


The BatteryMINDer 12248 will safely charge any 12V type and size of lead-acid battery, including dry sealed gel, wet, maintenance-free spiral and AGM. The built-in safety system ensures that the batteries will never be overcharged.

Users can select from 2, 4, or 8 amp settings, by simply pushing a button.


3-Stage Charge


There are 3 stages involved in the charging of a battery using this unit.

1) Constant Current: In this stage, the battery gets charged to approximately 80% of its capacity.

2) Constant Voltage Absorption: This means that the voltage is maintained at a pre-set level.

3) Pulse with Modulated Float: The voltage is maintained at a constant level; if that level drops below 95%, a pulse of electricity is injected. This helps your battery maintain satisfactory levels, even when it isn’t being used.




The built-in desulphator automatically dissolves sulphation, which can cause a battery’s life to shorten considerably, and lessen the power. It uses a sweep pulse technology in high frequencies in order to accomplish the desulphation.

This is commonly used for batteries that have been sitting for a long period of time and has lost all power.




This unit is light and compact, weighing just over 3 pounds. It is fully transportable and can go virtually anywhere.

The power cord is 6 feet in length, making it suitable for most charging jobs.
