How to Test Golf Cart Batteries

When golf cart batteries start to go bad it can be hard to notice. However, if the telltale signs are ignored for too long, LSV enthusiasts may find themselves stranded with an inoperable low speed vehicle. To avoid being stuck in such a predicament, owners of Club Cars, Ez GOs, and lifted golf carts are encouraged to test LSV batteries from time to time. Find out how below.

 

Telltale Signs to Look For

 

Before any battery dies, the utilities powered by the energy capsule become less effective. This inevitable process is witnessed when headlights start to dim, or interior lights start to fade. From there, the next aspect typically affected by a decrease in power are internal items that rely on spark plugs.

 

When this occurs, golf cart performance issues become more pronounced, or event rampant. This phenomenon can be witnessed when Club Cars, EZ Gos, or luxury golf carts suddenly come to a standstill while in operation, or does not fire up when you turn it on. Savvy golf cart owners aiming to prevent the aforementioned battery related issues before they become a major problem should test LSV batteries at least once a month via the following steps.

 

Steps to Take During Testing

 

On average, golf cart batteries need to be recharged once every two months. If this schedule is adhered to, many energy capsule units can last as long as seven years without any noticeable noteworthy issues. That said, conducting the steps below takes all of the guesswork out of determining if a golf cart battery is going bad.

 

  • Charge up each batteries to full capacity
  • Starting with the first battery charged, hook the charger back up to it
  • Get a voltmeter and add the positive lead to the positive battery terminal
  • Repeat for the negative
  • Record the voltage reading
  • Continue until data from each energy capsule is recorded

 

Afterward, compare the readings. If all of the batteries are functioning as intended, the voltage readings should be about one volt higher than a single battery. To elaborate, here are the anticipated readings for a 36 volt and a 48 volt golf cart with six batteries with six volts each.

 

  • 36 volt LSV: the reading for each battery should be about 7 volts
  • 48 volt golf cart: typically has a 9 volt read out for each energy capsule

 

In the event that all golf cart batteries pass the voltage test, move on to the hydrometer test. This process is used to determine the ratio of water to acid in a battery. In case you are not familiar with this concept, an energy capsule loses its ability to hold a charge as the acid breaks down into water. Furthermore, the aforementioned transition typically happens faster in cheaper batteries than in high-quality energy capsules.

 

To conduct the hydrometer test, put on safety goggles. Then, use the hydrometer to record the readings for each battery. Energy capsules with a 1,100 reading are comprised of mainly water, whereas results close to 1,300 are predominately acid. Replace those with only water inside.
