7 Stage Charging


BatteryMINDer® Seven Stage Charging Process Explanation

The following BatteryMINDer® models have a seven stage charging process: 1500, 1510, 1215C, 2012, 2012-AGM, 128CEC1, 244CEC1, 483CEC1, 128CEC1-AA-S2,3,5, 244CEC1-AA-S2, 3, 5, 28252-AA.

These models come equipped with sensors for Automatic Temperature Compensation (ATC) from 0°F to 130°F. These sensors are either Ambient (ATS) already installed or the optional At-the-Battery (ABS-248) depending on the model. This ensures 100% charge without ever over- or under- charging.  The sensor accomplishes this by sending electrical information to charger so it will know when to lower its voltage (warm-hot) or raise voltage (cool-cold).  The purpose of the optional ABS-248 sensors is to detect temperature at and within the battery itself rather than the temperature surrounding it or the charger. This is very important if charger is not close to (in same ambient atmosphere-temperature) as the battery.  Proper temperature compensation significantly increases battery lifeAny charging device that is not equipped with accurate temperature sensing should never be used in temperatures above 80°F and below 60°F, especially when being maintained for weeks-months at a time. If used expect battery life to be significantly shorter with poorer performance during its shortened life as well. 


The Seven Stage Charging Process: 

Analyze - Test-Qualify/Accept or Reject battery

Desulfate - Begins removal by dissolving harmful sulfate

Soft Start - Applies low current if battery tests low

Bulk* - Provides maximum output to charge to 85%

Absorption* - Provides low current to complete to 100% 

Test - To determine if battery needs further desulfation

Maintenance - Maintains temperature-compensated full-charge


*All BatteryMINDer® models provide 100% full-time variable frequency pulse type desulfation** automatically (no buttons to push).
