Best Battery Charger For Deep Cycle Batteries
Best Battery Charger For Deep Cycle Batteries
BatteryMinder 128CEC1: 12V 2/4/8 AMP Battery Charger - Maintainer - Desulfator
  • EIGHT BATTERIES AT A TIME - Maintains up to eight batteries at a time when connected in parallel. Requires the use of Y-Connectors 210AY (sold separately). Ideal for winterizing Cars, Trucks, Motorcycles, ATV, Boat, RV, etc. The 90-140 VAC 47-63 Hz input allows for worldwide use.
  • AMBIENT TEMPERATURE SENSOR– Temperature compensation precisely adjusts battery voltage based on temperature sensor readings. This ensures your battery will always be properly charged and maintained no matter what conditions it is subject to. Reverse polarity, short-circuit and over temperature protection.
  • EXTENDED BATTERY LIFE: Automatic full-time desulfator reverses sulfation (a buildup of lead sulfate crystals) - the primary cause of early battery failure by using a patented range of high frequencies to safely remove sulfation and recondition weak batteries. Sulfated batteries once considered beyond recovery can now be brought back to long-term useful condition; extending battery life up to four times when compared to new batteries not being properly maintained.
