MajorCharge Pro Battery Chargers can be used to recharge virtually any type of battery, including conventional liquid electrolyte, maintenance-free absorbed electrolyte, deep-cycle, and gelled type batteries. The MajorCharge Pro features patented three-stage constant current, constant voltage charging format.

A constant current bulk charge MajorCharge Pro applies to achieve the fastest possible return of energy to the battery. This constant voltage stage is proportionally timed and temperature compensated, minimizing electrolyte breakdown and gas emission. The final standby float charge stage will replace standing losses and keep the battery in a fully charged state & "Ready" mode. As soon as the battery is connected, a desulfation circuit encourages the breakdown of large sulfate crystals which can develop during prolonged periods of deep discharge.

• Electronic Short Circuit & Reverse Polarity Shutdown
  • Without blowing fuses; an exceptional safety feature.
• Built-in Electronic Timer
  • Monitors the time taken from start of charge until the battery voltage reaches the first preset voltage limit. The time duration for the second stage is automatically calculated in proportion to the time taken for the first stage. Specifically designed to optomize charging on a wide range of battery types, ages and sizes.
• Customer-Preferred LED Amp Gauge
  • Indicates the current output without fragile, moving meters or energy loss. A green, ready light indicates that the battery is ready for use or will flash if there is an override timeout.
