How to Make My E-Z Go Charge Last Longer

E-Z Go golf carts and utility vehicles use batteries in a series. Six batteries are usually connected. Making the charge last longer involves identifying problem batteries, performing charger maintenance, and allowing the batteries to reach their peak performance that E-Z Go calls "Maturity." These kinds of activities can be accomplished by following some steps.

      Allow the batteries to charge up to 100 times before they reach maturity. Maximum capacity will occur at maturity. The capacity will gradually be reduced as the battery gets older after it has reached maturity.

      Identify bad or old batteries that may be bringing down the overall performance of the battery set. Insert a hydrometer into each battery consecutively, and squeeze the bulb while the tip is in the electrolyte. Look at the color of the liquid. If it's brown or grey, the battery may be bad.

      Perform a more thorough test if you suspect any batteries are bad. Suck some more electrolyte into the hydrometer and let the float become free. Look at the reading where the electrolyte meets the scale. Add or subtract four points to the reading for every 10 degrees that the electrolyte temperature is above or below 80 degrees. Test all of the batteries. They should all be within 50 points of each other -- if one or more isn't, replace it, or them.

      Make sure that the charger is turning on if the batteries aren't getting charged properly. Plug the charger into the cart's receptacle and makes sure the light comes on. If it doesn't come on, or if more than one cart isn't receiving a full charge, have the power outlet on the wall looked at by an electrician. Low voltage may be the cause.
