With 11 charging algorithms, IP22 protection and increased efficiency, Sterling's Pro Charge Ultra represents fantastic value for money. Let's take a closer look at the key features of this fantastic battery charger.

Synchronised Rectification
Modern, synchronised rectification with MOSFET technology makes the Pro Charge Ultra Series 9% more effective. Less heat liberated and increased efficiency are also features of this latest technology.

Elegant Yet Functional Design
the Pro Charge Ultra housing was designed by a renowned American product designer. Featuring function and clean lines on the outside, and a housing constructed from plastic with a corrosion resistant non-magnetic metal used as the back. 

Splash Protection
For vertical mounting, the unit has drip water protection. The protection is class IP22. Meeting requirement of the ABYC drip test. 

Variable Fan Speed
The internal temperature of the device ultimately runs the speed. This guarantees a minimum possible noise. Known as 'thermostatically controlled draft cooling'. 

Programmable Power Consumption
The Pro Charge Ultra can also charge with the following performance levels 100%, 75%, 50% and 25%. This can be controlled either from the front panel, or by programming the remote control. The power reduction system is  often used when the power supply to the charger is inadequate such as with a small generator, while still enabling competent levels of battery charging. Another benefit of the power reduction system is reducing fan noise due to less heat in the system.

11 Preset Charging Algorithms
The Pro Charge Ultra has 11 different charging characteristics for corresponding types of batteries: Gel, AGM, sealed, open, calcium, LiFePO4. If these presets do not suffice, there is a single customisable setting that can be used. Enter the absorption and float voltages then press enter and the settings will save. 

Automatic Desulphation/Equalisation
About once a week, the Pro Charge Ultra will perform a desulphation/equalisation and anti-stratification program. Helping to keep your batteries young and rejuvenated. 

Voltage and Current LED Display
Two LED matrix display are built in, with one to display the voltage output from the charger, while the other displays the current leaving the charger.

Performance Monitoring LED Bar
A bar of LEDs is in place to display the percentage the battery is operating at. Allowing quick and easy recognition of charger status. 

32 LED Display
32 built in LEDs provide a full range of necessary information about the charger, such as charging status, battery chemistry select, temperature and voltage warnings, to list just a few. 

Redundant Safety System
In the event of a failure of the main processor, this unit provides another safety system to shut off the device. Doubling the levels of security.
