On diesel engine fire pumps, the engine is started by batteries. Diesel fire pump controllers generally supply two separate battery banks with independent chargers and alternate cranking between the two batteries. Capacity, engine requirements and compatibility with the controller's charger are evaluated together when selecting a diesel fire pump starting battery.
The Bosch T5 is a commercial vehicle starting battery in the Heavy Duty Extra class. Bosch describes the T5 as a battery with high cycle resistance that provides reliable cranking power even after long standby periods. This is important for diesel pump engines that remain on standby for long periods.
The patented PowerFrame® grid improves current flow and reduces corrosion. A labyrinth lid returns condensed water to the battery; the battery is completely maintenance free and leak-proof. Thanks to its robust construction it has V3 vibration resistance according to the EN standard.
The T5 series is offered at 12 V in 145 Ah, 180 Ah and 225 Ah capacities. Battery capacity should be selected according to the requirements of the engine manufacturer and the controller. Bosch does not have a separate product line named 'fire pump battery'.
