Battery Brain - Vehicle Battery Monitor

Battery Brain prevents a dead battery by using patented technology to continually monitor a battery’s charge strength and isolate it from any possible energy drainage, ensuring enough charge is preserved to start the engine.

The Battery Brain unit can be mounted in various configurations on the positive terminal of the vehicle battery. It monitors the voltage in the battery and if this drops below the prescribed level needed to start the vehicle (e.g. 12.1V), a brief timed sequence measures whether this is a temporary drop that recovers quickly.

If not, Battery Brain disconnects the battery from the vehicle’s electrical system to preserve the charge. The battery will then typically recover (e.g. to around 12.6V) but it will at very least retain enough charge to start the engine.
The basic models then only need to be reactivated using a button on the unit under the hood to start the engine. The Gold models are supplied with a wired switch which is mounted in the interior of the vehicle which reactivates the unit easily to reconnect and start the engine.

Battery Brain’s patented technology comprises a unique conductor that operates in an oxygen-free environment and can tolerate high currents.

It measures temperature, current, voltage and voltage direction and using mathematical logarithms, disconnects the battery at a charge level sufficient to start the engine.
