EACH mtu GENERATOR SET COMES WITH A HEAVY-DUTY COMMERCIAL BATTERY AND AN OPTIONAL BATTERY CHARGER.
Lead acid batteries are standard with Nickel Cadmium (NiCd) batteries optional, and Automatic 3-stage battery chargers are available in 12V or 24V and operate using utility power.
Dead batteries are the #1 reason that generators fail to start. NFPA 110 calls for the inclusion of an automatic charger system that operates without any manual intervention. Batteries should be inspected regularly and replaced every 3 years for optimal reliability. We recommend checking the battery weekly including checking the battery voltage and charge rate.
Lead acid batteries are the most common type of battery for generator sets:
- Economical and work well in most applications
- Can be recharged with conventional battery chargers
- Available in “maintenance free” and flooded-cell types
- NiCd batteries are specified in extreme temperature conditions, but are more expensive, require special battery chargers, and require hazardous material disposal
Automatic battery chargers read the battery’s state of charge and adjust the volts and current output through the three stages of charge:
Stage 1 – Battery charged at a constant current to set voltage
Stage 2 – As the battery saturates the current will reduce
Stage 3 – Float charge compensates for battery self-discharge
Curtis Power Solutions offers replacement batteries and battery chargers to ensure that your power system starts when called upon.
