1. Longer charging time:

The chemicals inside the batteries have their specific shelf life. The performance of batteries gradually decreases when it is in regular use. Even if the charger does its best to charge the batteries, they will take a longer time to be charged. Usually, golf cart batteries need to be charged overnight to provide full power to the vehicle the next day.

If the batteries take more time to be charged, you should replace them, as the cells of the battery break down eventually over time, and some batteries may not be fully charged as well.  

2. The hills will feel like mountains:

Golf carts are not made to run through the vast hills, but they should brisk through small knolls. You need to replace your trojan golf cart batteries if the following scenario occurs—

When you need to press the accelerator forcefully all the way, when small hills take more power from the cart and it cruises afterward on the downhill, you need to replace the battery.

3. Accessories cannot work well:

Usually, a Best golf cart covers a few miles on average. When the battery is in a good condition, it can easily cover about seven miles without recharging. As the battery loses its strength, it won’t cover as much distance as you desire. When you notice any sign of trouble, do not go further, consider getting back and quit using it for the day, because the carts are heavy and giant so you can not push it and get back to the club, this idea won’t work at all.

Lithium Golf Cart Battery vs Lead Acid Golf Cart Battery Talking Points 

Since the market is saturated, you will find different types of batteries. Among them, Lithium and lead-acid are leading the market. So which one should you pick? Well, let’s have a discussion to find the best one.

Weight

The weight of the battery has an impact on the speed of the cart. If the battery consumes more space and increases the speed, the cart cannot reach its maximum speed. On the other hand, a small and lightweight battery can help the cart get its highest rate.

Compared to the Lead Acid golf cart battery, the Lithium battery weighs half. Also, it takes less space than the Lead-acid battery. So to enhance the speed and performance, a Lithium battery will be better.

Life cycle

The life cycle depends highly on the charge cycle. An average lithium battery has a charge cycle of 2,000 to 5,000 times. On the other hand, a lead-acid battery can deliver a maximum of 500 to 1,000 charging cycles. That means the lithium battery will provide a better life cycle.

Maintenance

People don’t like maintenance at all. For that, lithium batteries have gained massive popularity. The reason is, it requires little to no upkeep where lead-acid batteries require regular maintenance.

Charging speed

To run the cart, you have to charge the battery. If it takes too much time to charge the battery, you cannot enjoy the fun of playing golf. Both the batteries offer good charging speed. However, lithium batteries have better-charging speed compared to lead-acid batteries.

In general, a lithium battery takes half an hour to be charged at 80% level. On the flip side, it takes around 8 hours for the lead-acid battery to be fully charged.

Battery compatibility

Some golf carts are compatible with lead-acid batteries where some are good with lithium. In that case, you have no option but to pick the compatible one. If you want to install lithium batteries, it will take additional installation costs. So in terms of compatibility, choosing the compatible one will be a good choice.
