Monobloc traction batteries must be able to provide a constant current over a long period of time. The open lead acid batteries do require some attention to maintenance, such as topping up the cells. This can be time consuming and should not be forgotten, to help you with this, we also offer an automatic filling system (see below for more information). The positive plates of the monobloc traction batteries are specially made of tube plates instead of flat plates.
Monobloc batteries combine a very high capacity with a maximum lifespan of 1200 cycles. This long life is due to the tubes of plates.
