Yet, just like any other internal combustion engine, lubrication, cooling systems, fuel systems and electrics can develop faults. Paul Brickman from Crestchic load banks explores some of the common reasons for generator failure. Battery failures . One of the most common causes of generator problems is battery failure. In short, a failed battery ...
3. Over-cycling – After a UPS operates on battery power during a power failure, the battery recharges for future use, an event called the discharge cycle. When a battery is installed, it is at 100 percent of its rated capacity. However, each discharge and subsequent recharge slightly reduces the capacity of the battery. 4.
