Sterling Battery to Battery Chargers

Battery to Battery Charger

On the surface this may look like another way of having an advanced regulator without wires and in a way it is, however this method has a specific market in mind and like the advanced regulator and the voltage amplifier it has a very precise slot which it has been designed for and fits in there perfectly.

Why do I need the D/C battery charger?
By know I hope most people understand that the best way to charger a battery is using a 4 step battery charging curve (which cannot be achieved from a standard alternator). This system enables one to simply attach the unit to a standard engine battery and it will fool the alternator into working at its maximum ability, this will ensure all its surplus power is used to charger the auxiliary battery bank to its maximum. This system is designed to use only the surplus power and ensures that at all times the power required to run the primary system (the vehicle system or the boat engine) is not affected. The surplus power is converted into a higher voltage and used to charge a secondary battery bank using a digitally controlled programmable 4 step charging curve as per all the other high charge products Sterling makes.
What performance improvements would I expect?
In a nutshell it charges your extra battery system about 5 times faster than it would otherwise charger and puts about 100% extra use full power into them and increases the life of the battery by de-sulphating them.
For best effect use open lead acid batteries, avoid gel, sealed and AGM batteries.
How does it work?
The unit monitors the engine start battery, the unit will not start until the battery voltage exceeds 13 volts, then it waits for 2.5 minutes to ensure that some charger is replaced after engine start, it then pulls the engine battery down to no less than 13 volts, this enables the engine battery to still receive a charge and ensures the alternator works at its full potential to further ensure the engine battery is OK.

Other features included in this system include remote control option, alternator temp sensing, battery temp sensing, ignition feed (if required), automatic start and shutdown. Its extra features and charging curves (software program) are very similar to the alternator to battery charger.

CTEK Battery to Battery charger

CTEK Battery Chargers


CTEK Battery to Battery Charger



If you rely on battery power without access to shore power / 230V hook-up, this new product from CTEK should be high up on your shopping list. When used in conjunction with the right batteries, a suitable solar panel and CTEK's SmartPass, it really can allow you to stay off mains hook-up indefinitely.

The Dual 250S is an intelligent, five-stage battery charger that works in much the same way as CTEK's other chargers, The big difference is that this model is powered from a vehicle's or boat's starter battery so that the domestic / auxiliary batteries are efficiently charged whenever the engine is running,

With a continuous output of up to 20 Amps, the effect of this piece of equipment is much faster charging of the domestic / auxiliary batteries and longer life for the batteries too.

An additional benefit of this charger is that it incorporates a solar regulator with MPPT (Maximum Power Point Tracker) technology. MPPT can increase the amount of current put into the battery from the solar panel by as much as 25% compared to an ordinary regulator.

Input voltage: Max 22V DC
Output voltage: Max 14.4V DC at 25°C
Charging current – max: 20 Amps
Can be used with battery types: All 12V lead-acid batteries including: Wet, A.G.M, gel, calcium and maintenance free. 40Ah - 300Ah
Protections: IP65 (splashproof & dustproof) battery temperature sensor included. Unit only starts working when the starter battery can supply surplus power
Remote control: Not applicable
Dimensions - W x D x H: 1192mm x 110mm x 65mm
Warranty: 24 months
Weight: 0.7 Kgs

Supplied and Fitted from:
CTEK 20amp 12v - 12v Batt to Batt charger £375.00

CTEK Mains chargers

Ctek's range of 12volt and 24volt battery chargers are recognised the world over as being the best you can buy. For Caravans, motorhomes, vans, horseboxes and boats.
