The batteries on your golf cart are designed to hold their charge while the power is turned off and they’re not in use. However, there might be an issue in the speed controller or another component of the golf cart that’s causing your battery to draw power when it’s not in use. Many batteries can lose up to 1% of charge per day.

How does a battery work?
Your battery works by having two metals, a cathode and anode, react to each other to create chemical energy that we harness as electrical energy. With wet cell lead-acid batteries, these metals are kept in a liquid electrolyte, a liquid solution comprised of pure water and hydrosulphuric acid mixed to a set specific gravity. Other types of batteries typically use a gel, mat, or solid electrolyte to perform the same function. For the purpose of this topic however, the only battery we’ll be discussing is the traditional lead-acid battery, as this is the only type of battery for which you will have to worry about electrolyte levels.

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 many amps does a golf cart battery take to recharge?
To recharge, the batteries will require 90 ampere-hours + 20% to make up for any charge deficiency.
1. Excretion of Hydrogen Gas
When it comes to the main reason why golf cart batteries blow up, the answer is simple; golf cart batteries excrete a flammable and combustible fume known as hydrogen gas. Hydrogen gas is a by-product of batteries that occurs during a chemical reaction involving the water and sulfuric acid solution and lead plates.
2. Poor Quality Chargers
If you are using a charger that is poor in quality, you will be taking the risk of causing an overcharge to occur (which will be discussed further later in the article) and ultimately producing an explosion. Overcharging, along with blocked or clogged vent plugs, can cause the by-product hydrogen gas to accumulate within the cell.
3. Clogging in Vent Caps
Golf cart batteries require a vent in order to release the gases and fumes that form inside the pack, if the vent plugs or caps become clogged or blocked from dirt, corrosion, or dust, the accumulation of hydrogen gas is highly combustible.
4. Frayed or Corroded Battery Cables
A very important part in proper maintenance for your golf cart batteries is ensuring that all cables connected to the battery have no fraying or corrosion.
5. Wet Battery Lids
At some point, your batteries will secrete some battery acid while charging. Hydrogen gas is produced at a rapid rate and causes bubbling and boiling as the acid spills over onto the lid of the batteries.
6. Sparks or Fire
Due to the combustibility of hydrogen gas, when it accumulates within the battery pack, a single spark or flame can cause the batteries to blow up. Once the amount of hydrogen gas inside a room reaches 4 percent, it becomes highly combustible.
7. Overcharging
Poor quality chargers can continue to charge your batteries past their initial stopping point, especially if you need to replace any of the batteries in the pack; it is always recommended that you change every battery within the pack in order to reduce the risk of unbalanced charging.
