EINHELL Battery Charger BT-BC 12 D-SE

The BT-BC 12 D-SE is a automatic battery charger controlled by a mirco-processor. This means, its especially to charge maintenance-free batteries as well as for long time charging and for charge maintenance from batteries which are not permanently in use, such as boats, lawn mowers and whatnot.

Due to the integrated mirco-processor the charging curve has 3 steps.

Step one charges the battery with nearly constant current up to approx. 85%, step two with constant voltage up to approx. 95%. Step three keeps the battery voltage constant (IUoU-charging characterisic) and so is the battery always fully loaded.

Therefore is the tool also for lead acid batteries and gel batteries optimally proper. A integrated fault diagnose system advise at the LED-display onto battery fault and connection problem.

The charging will be controlled electronically and accordant indicated. The charging current can attuned to 2 / 6 / 12 ampere.

This battery charger has also a 12 V d.c. output socket which provides working power up to 140 Watts for 12 V d.c. operated appliance.

Einhell worldwide

Since its foundation in 1964, Einhell has developed steadily and always remained aware of its local roots. The company has grown from the Hans Einhell GmbH, based in Landau an der Isar, to a corporate group. But the headquarters of what is now Einhell Germany AG remain in Landau where it all began. The company took its first step in an international direction in 1968 with a production site in Spain.

And now the Einhell Group employs some 1,500 people in over 39 countries across the globe. The company’s products are sold in over 90 countries, which in 2017 resulted in a turnover of approx. 550 million euros for the company. The next target markets are already in the sights of the global group and will be implemented in the next few years.

Outstanding service and innovative products, such as the Power X-Change battery system, should impress customers and contribute to sustainable, international growth through long-term planning and sound business practices.
