Is your Grand California not being used for a long time and is not connected to shore power? This can lead to problems after just a few days of downtime. Unfortunately, the starter battery discharges very quickly and after a few weeks it can be so deeply discharged that it can no longer be saved.
Does your Grand California have a solar panel? Then our Battery Maintainer is just the right gadget for you! It can be connected to the fuse box of your Grand California via plug & play in just two minutes. From then on, your starter battery will be automatically charged via the solar panel on the roof - a function that is not available as a factory feature!
As soon as the auxiliary battery reaches a charge level of 80%, the excess energy is used to constantly charge the starter battery. The maximum charging current is 3 A.
The Battery Maintainer can remain in the vehicle permanently – even during use or when the Grand California is connected to shore power. A one-time installation is sufficient!
——
The function of the Battery Maintainer is compatible with the factory equipment of the Grand California. However, modifications to the electrical system, such as the installation of a lithium battery, can affect the correct function.
For example, if a lithium battery is installed, the starter battery is charged directly and independently of the charge level of the lithium battery.
