MILWAUKEE — Due to the increasing demand for better fuel economy and more sustainable technologies, Johnson Controls announced Wednesday it will expand its production of advanced batteries for Start-Stop vehicles.

The company will increase its existing Absorbent Glass Mat battery capacity in its Toledo, Ohio plant, bringing the overall invested amount to $130 million since the start of production for this technology in the U.S. in 2012, according to the announcement.

Another factor in Johnson Controls’ decision is that car makers are needing to replace conventional technologies with more efficient ones as the government tightens fuel and carbon emissions measurements.

Start-Stop enables up to 5 percent fuel economy savings compared to a conventional vehicle.

The technology automatically shuts off the engine when the car is idle and restarts it when the driver’s foot leaves the brake pedal.

During this time, the vehicle’s electrical systems — from entertainment to lights — use energy from an advanced lead-acid battery rather than the gas-powered engine, thus saving fuel.
