Self-sufficient campers know the situation: Even the standby consumption of an alarm system or the switched-on radio can be sufficient to bring a starter battery to its knees within a few days. So it can happen that the engine does not start when leaving for the next destination. Not so if you have a Dometic Büttner MT Standby-ChargerPro onboard. The compact device permanently monitors the state of charge of the onboard and starter battery and – whenever possible – feeds excess charging current (e.g. from the solar panel) into the starter battery. Suitable for all types of onboard batteries, also for modern LiFePO4-vehicle batteries. Ideal for self-sufficient camping or when the vehicle is not being used for a long time.
