This should be the last portable battery charger you ever buy and it's Waterproof! Temperature sensor included with purchase of the charger.
Safelycharges 70% - 200% faster than any/all known conventional constant voltage chargers. Guaranteed 100% full charge to ALL TYPE / SIZE / BRAND 12-Volt batteries, without ever overcharging them.
- Maximizes cycle life and performance of all three (3) types* of lead-acid storage batteries, regardless of size / type / brand.
Push button selectable type and charge rates for all size / type / brands of 12- Volt batteries, including flooded (filler caps), sealed Absorb Glass Mat (AGM), and Gel.
3 Stage (constant current bulk- constant voltage absorption-pulse width modulated float) ensures 100% full charge capacity of all battery types.
- Full Time random sweep desulphation**.Desulphates faster and more effectively than any known charger or stand-alone desulphator-conditioner.
- Spark-proof, short circuit, reverse polarity and over-temperature protected.
Automatically detects defective batteries and rejects them.
Includes built-in soft startfor voltages down to 3 volts. If battery voltage does not increase to 10.5 volts within a predetermined time, the battery is rejected.
- Polarity reversal-Error indicator.
- Auto-reset thermal breaker (protects both battery and charger under abnormal conditions such as a shorted cell and /or excessively high ambient temperatures)
- Manual override for maintenance- desulphation only long term storage mode.
- Rejects a damaged or open cell (shorted) battery.
- Watertight enclosure with conformal-coated protected circuitry.
- Extremely light weight (2 lbs.) compact size- 5.5 x 5.5 x 2.25.
- Portable or OnBoard mountable.
- Built-in battery condition indicators: detect and display charge level modes, charge retention and existence of sulphation.
- Automatic temperature compensation w/ optional battery temperature sensor. Sensor can be used to detect and adjust chargers output voltage depending on temperature, extending battery life and performance by more than 100%***.
1 year 100% Money back Guarantee plus 5 year no hassle warranty.
