Modern vehicles rely on many features that draw power from the battery. A onboard battery charger maintains performance and ensures that your vehicle will start.
Cold weather, comfort functions, and a standard driving pattern will deplete your battery faster than the alternator can recharge it. When the battery becomes discharged, it might not be able to start your vehicle. The MultiCharger Flex maintains the ideal state of charge also in extreme weather conditions. A charged battery makes the car easier to start, even on cold days, and extends battery life.
A continually low charging level or repeated discharges will damage your battery. If this happens, replacing it is often the only alternative. Discarding batteries is expensive and harms the environment. A MultiCharger Flex maintains the health and performance of your battery and extends it’s expected lifetime. DEFA WarmUp assemblies include a MultiCharger 1203X.
The DEFA app gives you full control over your WarmUp system and lets you monitor your battery status. The app will visually notify you if the cable is not connected when you try to turn on the system and alert you if the cable is still attached when you start the vehicle.
MultiCharger Flex can be used to charge all 12V lead/acid batteries, including AGM and GEL.
