Proper Battery Watering Extends Battery Life

Published: 5/11/2015 Author: Julie Elliott, Marketing Director, Battery Watering Technologies Category: Maintenance Tips
Properly watering lead acid batteries is one of the most important maintenance tasks that can be done for an electric vehicle.  It is time consuming and extremely cumbersome.  Under-watering and over-watering lead acid batteries are the two biggest issues electric vehicle owner’s have.
Electric vehicle owners either don’t routinely add enough water or they simply put too much water in the batteries.  Under-watering batteries can expose the lead to oxygen inside the battery which decreases the life of the battery.  Over-watering the batteries can cause boil over’s which decrease the life of the batteries by diluting the electrolyte and eating away at cables and terminals.  Most battery manufacturers prefer the electrolyte level to be filled to ½” below the neck inside the battery cell.
There is a right and wrong time to water a lead acid battery.  Electric vehicles, depending on how often they are used, need water at least once or twice a month.  The rule of thumb is to water batteries after a full charge. The electrolyte levels inside the battery rise during the charge cycle and fall during the discharge cycle. If watering is done prior to charging they may boil over.
Battery Watering Technologies offers a safe alternative.  Using a single point watering system to water batteries to the correct level relieves a lot of stress. No more removing vent caps and exposing the user to acid. This is a risk taken each time a battery is manually watered. Water flows through a single connection filling each cell accurately and efficiently.  An electrolyte level indicator eye gives a visual indication that the valves are working properly and the batteries have been filled.  The entire process takes less than 30 seconds.  It is a safe, fast way to water batteries. 
Battery Watering Technologies single point watering system combined with their i-Lite™ sensor
Another great option to determine when a battery requires water is to add an i-Lite™ sensor.  This electrolyte level indicator provides a bright visual indication when water is needed. When the sensor light is red, it is time to water the battery. When the light is blinking red, it indicates that the battery has needed water for ten days or longer.  When the light is green, the battery is okay and no water is needed. Using an i-Lite sensor and a single point watering system on a set of batteries offer an ideal, effortless resolution to battery watering.
