How to tell if your golf cart battery is bad?
Symptoms of a failing battery or batteries could include the following: 1 You may notice the range decreasing over time. The range should be about 2 rounds of golf. 2 A “Shutter” is when the cart feels like you are running across a corduroy road or someone is tapping the brake in a rapid staccato. This is a classic sign of low voltage. If this is experienced, your cart may be low on charge, the charger may not be functioning properly or you may have a battery issue. 3 On electric golf carts, the cart refusing to move at all on a charged set of batteries could be the controller not engaging when the voltage falls below a preset value. 4 It takes twice as long to charge your batteries as it did when you first had them installed. As the batteries age, they will not hold a charge as well as they used to. The charger has no way to know this and will continue to charge the batteries trying to get to a full charge – meaning it will take longer to charge the batteries than normal.
How to tell if your golf cart is low voltage?
You may notice the range decreasing over time. The range should be about 2 rounds of golf. A “Shutter” is when the cart feels like you are running across a corduroy road or someone is tapping the brake in a rapid staccato. This is a classic sign of low voltage.
How many volts should a golf cart battery be?
For example – On a full charge a good set of golf cart batteries will allow you to surely play a few rounds of golf. Using a 48 volt Club Car for example you can play a round of golf with a new set of fully charged batteries and after round is complete the cart will still be above the 48 volt threshold on the battery banks capacity. One because the start / stop load not very demanding vs all out start stops continuously without letting the golf cart or batteries catch their breath per se… Though this is also because a fully charged 48 volt cart with say 6x 8 volt batteries will be around 51 volts not 48 volts.
Why is my golf cart battery undercharging?
Undercharging: Undercharging caused by using a cheap golf cart battery charging system ( One that does not apply enough amperage in the charging cycle) can cause lead sulfate to gradually build up and crystallize on the plates greatly reducing the. battery’s capacity and ability to be recharged.

How does a Lester golf cart battery charger work?
The Lester Electric Golf Cart Battery Charger you purchased is a transformer style charger that is designed to apply amperage and voltage for a length of time that replaces the energy used from last discharge. This is fairly old technology but very effective to charge your golf cart batteries. Depending on the battery chargers output (Amperage), the batteries size (Capacity), and DOD (depth of discharge), all this will determine the amount of time required to fully charge the battery bank in question. In the process as they reach maximum capacity the more electricity that is forced into the batteries the more it excites the electrolyte and gets electrons moving in the battery itself… (That is the boiling sound you hear)
How high does a 48V battery run?
No worries … I have seen 48v systems run as high as 58-60v when charging, but it is normal to see voltages around 50v-52v when sitting static for several days after a fresh charge cycle. Most common size lead acid batteries will be from .6 volts to .8 volts over advertised voltage on battery when fully charged. Always good to re-charge cart at the end of the day, never let it sit 1/2 -3/4 charged. re-charge then store when not in use.
Why are AGM batteries so picky?
