How Long Do Trojan Golf Cart Batteries Last?

Ever since Trojan pioneered the deep-cycle flooded golf cart battery in 1952, their products have been recognized as the standard in the industry.

90% of the best golf courses and Country clubs in the United States choose Trojan batteries to power their fleet of carts. The reason for this is the long-lasting lifespan their batteries provide.

The question that you are likely asking is, exactly how long do golf cart trojan batteries last? In this post, we are going to uncover that, however, the answer is not as straightforward as you may think.

According to the team at Golf Carts Plus, the short answer is 7 – 9 years. However, to achieve that you need to carry out the routine maintenance and watering of your battery. Furthermore, you need to do as much as possible to protect your pack from heat and vibration damage.

When it comes to watering, these batteries only consume distilled h20. Everyday mineral water will cause damage to the electrolytes and plates of the battery. Trojan considers this improper maintenance which will result in them not honoring their warranty.

It is imperative that your battery never runs dry and leaves the plates exposed, as this will cause irreparable damage to your unit. Conversely, it is vital to never add more water than is needed. Because this can expand the electrolytes, causing the battery to overflow. Overwatering can also lead to the dilution of the battery’s electrolytes, which impacts the performance abilities of the pack.

How Can You Extend The Lifespan of Your Trojan Golf Cart Batteries?

To ensure you optimize the lifespan of your Trojan batteries, it is essential to conduct routine maintenance. I have provided a list of tips to help you enhance the life of your unit.


When you install the pack, you need to make sure it is not tilted past 22-degrees. Anything beyond this point will prompt the battery to leak acid, which diminishes its performance and lifespan.

Maintenance and Watering

As I mentioned previously, Trojan deep-cycle flooded batteries demand religious maintenance and watering. If you do not check your unit every 2 – 4 weeks and forget to add distilled water, you will not get 7 – 9 years out of your batteries.

I have heard of golf cart owners that have tried to bypass the routine maintenance by not gassing their battery.

The Trojan company explains that this does minimize the need for watering, but this causes stratification. What happens is that the electrolytes at the top of the battery are light, while the ones at the bottom are heavy. This interrupts the performance of the battery and shortens its lifespan.

The optimal time to water your batteries is when your charge cycle is complete. Adding water before charging causes the electrolytes to overflow, causing permanent damage to your unit.

However, before charging the battery, inspect the plates to see if they are exposed to air. If they are, add sufficient distilled water to cover them for the charge. Once the charge cycle is complete, check the level and top up to the required level.

Electrolyte Level

We know that flooded batteries will damage if they have insufficient or excessive liquid. So, what is the correct electrolyte level? According to Trojan, liquid levels must be lower than ⅛ inches from the bottom of the battery’s vent well. And they can never go below the top of the plates.

Following this rule will go a long way in helping you achieve optimal performance and lifespan from your Trojan golf cart battery.


If you use your golf cart on a seasonal basis, it is obviously stored away for long periods of the year. Naturally, your batteries will self-discharge during this time. And if not monitored can run dead. Trojan’s deep-cycle flooded batteries discharge at an average of 15% a month in temperatures of 77º F.

Even if you are not taking your cart out for a few months. You should assess the gravity or voltage of the batteries every 4 – 6 weeks. Furthermore, when the battery hits 70% state of charge (SOC), you should perform a boost charge.

Finally, when you take your batteries out of storage, it is advisable to charge before use to ensure the battery is at its optimal level.

Neutralizing Electrolytes

Should your battery experience electrolyte imbalance, you must neutralize them as soon as possible to prevent further corrosion. Trojan recommends an old yet still effective remedy for this situation.

Apply a solution of baking soda and water. For every gallon of water, you will require one cup of baking soda.

Final Thoughts

In our review on ‘how long do Trojan golf cart batteries last?’ we realized that the answer is not straightforward. In an ideal scenario, you will enjoy 7 – 9 years from your Trojan battery, however, you must astutely follow the maintenance instructions to achieve this longevity.

Short cuts and laziness do not suit these batteries. They require TLC and will repay you with a long lifespan.
