Is Your Floor Cleaning Machine Undercharged?
Ninety percent of the problems maintenance crews have with their battery powered floor cleaning machines, is that they run out of power before they have time to finish the job. This is due to improper charging, where the batteries are not given enough time to reach full capacity and are starting the work day in an undercharged condition. If this is a constant problem, it can eventually lead to batteries that go bad before they need to, and this can be a costly addition to battery replacement costs.
There’s an easy way to find out the battery’s state-of-charge (SOC) with a simple hydrometer. First, make sure your floor cleaning machine is equipped with the correct deep-cycle batteries for that application. Using the hydrometer requires gloves, safety glasses and should be done in a well-ventilated area. Measuring the SOC of each battery cell and comparing hydrometer specific gravity readings to the specifications found on the battery manufacturer’s website, you’ll be able to determine if the battery is charged or undercharged. If it’s undercharged it’s imperative to give the batteries additional charging times. If the cleaning machines are always in use, try to find times to give them additional charge time during lunch breaks, or when workers may not be using the machines. This will ultimately extend battery life and increase the run times of the machines and add to productivity.
If, however, the batteries are charged for a long period of time and never seem to become fully charged, it can be an indication of other problems in the battery, or with your charger’s algorithms. Check with the battery manufacturer is these problems persist. For more information and tips to improve battery maintenance visit www.usbattery.com.
