In your Bürstner, the battery is an indispensable component for travelling independently and comfortably. It supplies numerous important consumers, such as light, refrigerator and water pump. To ensure that you always have enough energy available, there are three main methods of charging the battery.
Overview of the charging options
- Charging while travelling: While driving, the battery is charged via the alternator of the base vehicle - usually with the help of a charging booster that optimises the charging current. Depending on the booster, a charging current of up to 20-30 A is possible. This method is ideal for stopovers, although charging without a booster can be inefficient, especially in modern Euro 6 vehicles with an intelligent alternator.
- Charging via shore power (230V): The most reliable method for a full charge is to use shore power. The charger integrated in the EBL, usually with an IUoU charging characteristic curve, delivers a charging current of up to 18 A. Depending on the battery capacity (e.g. 100 Ah), a full charge takes around 6-8 hours. This method is particularly suitable for longer periods on camping grounds or at home.
- Charging via solar: Solar modules offer an environmentally friendly way to support the battery. With typical outputs of 100-200 W per panel and a recommended MPPT controller for higher efficiency, good performance can be achieved in direct sunlight, while this is greatly reduced in shade or cloudy conditions. Solar charging is ideal for maintaining the battery level during longer downtimes.
Overview of the battery types
- AGM battery (Absorbent Glass Mat): The AGM battery is often installed ex works in Bürstner leisure vehicles. It is characterised by being maintenance-free and robust. It is also position-independent and offers good performance for typical consumers.
- Gel battery: Gel batteries are optional or can be retrofitted and impress with their longevity and leakage resistance. They are ideal for solar operation, but are sensitive to high charging power.
- Lithium battery: The lithium battery is often retrofitted for greater self-sufficiency. These batteries are very light and offer a high usable capacity. They are characterised by fast charging times and a long service life, but require a special charger and a battery management system (BMS).
- Wet battery (classic lead-acid): Wet batteries are rarely installed in modern Bürstner models and are more likely to be found in older vehicles. They are inexpensive, but require a lot of maintenance and are dependent on their position, which means they are not ideal for modern motorhome technology.
Find battery information
- Directly on the battery: Type designation, manufacturer, voltage, capacity, technology
- In the logbook or manual: Technical data on the installed battery
- In the EBL (e.g. B. Schaudt EBL): Partial information on compatible battery technology
Example charging times for a 100 Ah battery
- Drive (booster): 20 A, 5-6 hours, only while driving
- Shore power: 18 A, 6-8 hours, full charge possible
- Solar (MPPT): 5-10 A, weather-dependent, supportive, not sufficient on its own
⚠️ Safety note
Carry out regular visual inspections of the battery to detect and repair any physical damage such as cracks or dents at an early stage. It is also important to avoid completely discharging the battery, as this can lead to permanent damage and a shortened service life.
💡 Our tip
Check the battery level on the control panel regularly so that you are always well informed and can react to changes in good time.
