Modern Sealed Batteries: No Watering Needed

The good news is that most modern golf carts use sealed AGM (Absorbent Glass Mat) or gel-cell batteries. These are designed to be maintenance-free, meaning you don’t need to add water throughout their lifespan. They’re built with a special internal design that traps the electrolyte solution, preventing evaporation.

So, if you have a newer model golf cart, you can likely skip this chore altogether.

Why Regular Inspection is Still Important

Even though sealed batteries don’t require water topping, it’s still a good habit to inspect them regularly. Here’s what to look for:

  • Physical damage: Look for cracks, bulging or warping in the battery casing. These could indicate internal damage and warrant a professional’s attention.
  • Corrosion: Corrosion around the battery terminals is a sign of a potential leak. Clean the corrosion with a baking soda and water solution, but consult a professional if it persists.

Traditional Flooded Batteries: A Different Story

If you own an older golf cart, it might still use flooded lead-acid batteries, the kind found in traditional gasoline vehicles. These batteries do require periodic watering to maintain proper electrolyte levels.

Checking Flooded Battery Water Levels: If you have flooded batteries, consult your golf cart manual for specific instructions. Generally, you’ll want to check the water level after a full charge. The battery cells will have visible indicators showing the ideal electrolyte level. Use distilled water to top up the cells if needed, but avoid overfilling.

When to Add Water to Golf Cart Batteries? Step-by-step guide

Here are some key pointers on when to add water to your golf cart batteries:

  • Check after a full charge: The best time to add water is after the golf cart has finished charging. This ensures you’re adding the right amount of water and avoids overflow during charging.
  • Frequency depends on climate and usage: Hot climates and frequent use will cause more water evaporation. In general, check water levels monthly, especially during hot summer months. Some recommend checking after every 15-20 charges.
  • Visually inspect the water level: Each battery cell should have a designated water level indicator. Look through a designated port on the battery to see if the water level sits below the top of the battery plates. If the plates are exposed, it’s time to add water.

Effects of Not Adding Water to Golf Cart Batteries When Needed:

Skipping out on adding water to your golf cart batteries can lead to some real trouble down the road, here’s why:

  • Exposed Battery Plates: The water in a battery helps keep the lead plates submerged in a solution called electrolyte. If the water level gets too low, the plates will be exposed to air. This can cause them to corrode and weaken, reducing the battery’s ability to hold a charge.
  • Reduced Battery Capacity: Damaged plates mean the battery won’t function as well. You might notice decreased performance, like shorter run times on a single charge.
  • Shortened Battery Life: In the worst-case scenario, severe neglect can lead to complete battery failure. You might end up needing to replace the whole battery prematurely.
  • Chemical Imbalance: Over time, the battery naturally loses water through evaporation. Adding distilled water replenishes what’s lost and keeps the acid mixture at the correct concentration. If you don’t add water, the acid concentration can get too strong, which can also damage the battery plates.
  • Reduced Performance: All this damage to the battery plates adds up to one thing: a weaker battery. You might notice your golf cart doesn’t go as far on a single charge, or it might struggle to maintain power when climbing hills.
  • Safety Concerns: Overheated batteries are a safety hazard. When they’re not working properly, they can overheat and potentially crack or leak.

Here’s a quick tip: Most golf cart batteries aren’t sealed and require periodic checks, usually monthly, to ensure the water level is within the recommended range. 

Use distilled water only, and avoid overfilling. If you’re unsure about any part of the process, consult a golf cart professional. In extreme cases, neglecting to add water can even lead to complete battery failure. So, it’s definitely worth keeping an eye on the water levels and topping them off with distilled water when needed.
