Frequently Asked Questions

RMI FAQ


My gas golf cart ran the other day, but now wont do anything. I've tested the battery and know its good. What's my issue? 

More than likely you need to replace the starter generator brushes. This is a very common issue. You'll need part # 529.

How often should I check the water in my batteries? 

Its a good idea to check it at least once per month. Adding distilled water when needed.

How much oil does my cart take? 

If you have a Yamaha then its 1 qt. If you have an EZ-GO, then its 1.5 qts. Needs to be changed once per year.

How often do I need to charge my batteries on my golf cart? 

You should give it a full charge at the end of every day of use.

How often should I have my cart serviced? 

Its a good idea to do it once a year. Gas cars should have the oil and filters changed every season. For electric carts, its good to have the batteries tested, transmission fluid changed, and brakes inspected.

When should I water my batteries? 

Water is lost during charging. Therefore, the best time to water your batteries is always at the end of the charge cycle. However, if the electrolyte level is extremely low or the plates are exposed to air, add some water to cover the plates before starting the charge cycle.

Can a battery freeze? 

The only way that a battery can freeze is if it is left in a state of partial or complete discharged. As the state of charge in a battery decreases, the electrolyte becomes more like water and the freezing temperature increases. The freezing temperature of the electrolyte in a fully charged battery is -92.0oF. At a 40% state of charge, electrolyte will freeze if the temperature reaches approximately 16.0oF.

Does my deep cycle battery develop a memory? 

Lead acid batteries do not develop any type of memory. This means that you do not have to deep discharge or completely discharge a battery before recharging it. For optimum life and performance, we generally recommend a discharge of 20 to 50% of the battery's rated capacity even though the battery is capable of being cycled to 80%.

Do batteries self-discharge when not in use? 

All batteries, regardless of their chemistry, self-discharge. The rate of self-discharge depends on the type of battery, the age of the battery, and the storage temperature the batteries are exposed to. As an estimate, Trojan batteries self-discharge approximately 4% per week at 80o F.
