Firstly, ask a well-qualified electrician to take a look at your electrical system. He will determine if the electrical capacity available is sufficient and if it can handle the battery charger’s demands while starting up the operation. Look at your electrical panel to see if the appropriate voltages are available. Followed by that, make sure that your charger matches those voltages.
You should be aware of the power available in the electrical panel: single phase or three phase. Three phase power is usually more cost effective when compared to single phase. It also charges the battery effectively than a single phase charger. So depending upon the space available in the power facility and the number of forklift trucks operated, you can choose a charger containing a backup charger in a single box. To state the obvious, having an extra charger in the same box not only saves a lot of space, but also brings down the price of the chargers.
The ideal gravity readings should be 1275 or above. Test each cell with the help of a multimeter by setting it to a 12-volt scale by putting the probes to each cell’s post. The reading should be 1.90 volts or above (on each cell). If it is below this reading, then you should understand that the cell is failing. Again, make sure to check the voltage.
The appearance will tell you a lot; if there are any corrosion on the tops and the links. If the cell tops are pushed upwards, then it is a sure sign of poor battery. It is time to change your forklift battery charger. Forklifts won’t perform well without a high-performance battery.
