Büttner standby charger Pro (LiFePo4) for starter batteries 12 V

When the vehicle is stationary, the on-board battery is primarily charged (charger, solar, fuel cell, etc.). If the vehicle is unused for a longer period of time, the starting battery will continue to be discharged due to battery separation. However, many vehicles also put a strain on the starting battery during the season because some consumers (radio, multimedia, parking lights, alarm system, etc.) are always connected to it.

The standby charger ensures that the starter battery is also charged - depending on the charge level of the on-board battery. The standby charger is suitable for all types of on-board batteries, including LiFePO4 (lithium).

Charge to the starting battery
When stationary, the on-board and starting batteries are separated from each other. Current cannot flow in one direction or the other. This also makes sense to protect the starter battery during downtime. Otherwise it would be discharged by the consumers together with the on-board battery and the vehicle could no longer be started.

However, it also prevents the starter battery from being charged if there is more than enough power on the on-board battery, for example from solar. Or the on-board battery is charged by a charger at the parking space that does not have a special output for the starter battery. In some touring vehicles, some of the starting battery is removed even when stationary (radio, clock, immobilizer, alarm system).

In order to also supply these additional consumers with power from the on-board battery, we have developed standby chargers. The devices monitor the voltages of the two battery systems and power is released as needed. With its 5 A, the Standby-LaderPro can also compensate for standby consumers. Anyone who uses lithium batteries (LiFePO4) as their on-board battery must always use the Standby-LaderPro
