How to Choose the Best 6V Deep Cycle Battery?

If you are still confused about choosing the most appropriate 6V deep cycle battery for yourself then you should go through these below-mentioned points.

Ampere hour rating

A deep cycle battery is required to work for long hours and it is better if you buy a battery with a higher ampere-hour rating of at least 200Ah.

Low self-discharging rate 

A battery with a high self-discharge rate will result in charging the battery again and again that most of the users of deep cycle batteries do not like.

Maintenance free

Though flooded batteries have their own pros but it will be beneficial if you buy a maintenance free AGM battery.

However, flooded batteries will also be a great choice if you are looking for a battery with a higher lifespan and a battery that can withstand a high discharging rate.

Apart from this, always go through the variety of applications that the battery is compatible for before purchasing it.

How to identify which battery fits your golf cart? Watch the following video:


How long do 6V golf cart batteries last?

Usually, it depends upon the appliance with which you are using the battery. But still we can give an estimate for an average of 45 minutes to 2 hours of continuous usage.

Should I leave the golf cart plugged in all the time with the battery?

Yes, you can however it’s all your choice, if you will leave it then it may get overcharged but not up to that extent that can harm the battery. Remember not to keep the battery plugged in for long durations in winters.

Why does the golf cart die so fast?

It may occur due to loose connections or corrosion on the battery terminals.
Removing corrosion and tightening up the connections may help, in the worst case scenario you should probably replace your battery.

What is the difference between 36V and 48V golf carts?

The 48V golf carts are designed in such a way that it uses ⅓rd less amount of current than the 38V golf cart. Therefore 48V golf carts are much more efficient than 36V ones.

Can i use a 36V battery with a 48V motor?

Yes you can, but you should not that it will decrease the efficiency of the motor. A 48V motor when powered with a 36V battery would only provide 75% of the maximum efficiency. So, if you want to run your motor to its maximum extent then you should power it with a battery having a voltage of 48V or more.

Final Words

The best deep cycle battery for you lies in the fact that it totally depends on the appliance for which you need the battery.

Hence, refer and acknowledge your appliance before you purchase the battery.

We tried to list down the best 6V deep cycle batteries available out there and we also listed some important points that you must know about deep cycle batteries.
