Potential battery issue on golf cart
 

I acquired a used 2020 Yamaha Quietec gas golf cart and the owner mention he keeps it on a trickle charger when not using. I believe (hopefully) this was code word for bad battery. It has a Striker monitor that shows speed and also voltage.

When I press on the gas there can be a noticeable lag between the engine starting and voltage will drop to 7 or 8v. I am thinking this is a bad battery and considering it's 5 years old, would not be surprising.

I thought I would just take out the battery and get it tested. However, there is a barrier that would need to be removed (or side panel) with fuses attached. Thinking I may just pay extra and have a repair guy replace it. I also want assurance that it is most likely the battery.

We just moved to the TV so not sure the best way to go about this. Does it make sense to take it to the Villages Cart shop, call mobile repair?

Suggestions are really appreciated.

I replaced the battery in my 2019 last year. Five years seems to be a common life expectancy for those batteries.

There are YouTube videos on how to remove the front (not side) panel to get the battery out. From memory:
- Remove the retaining clip holding the Forward/Reverse lever (only need a screwdriver to pry it off) then remove the lever.
- Remove the plastic plugs on the front and along the top of the panel using a screwdriver and/or pair of pliers.
- Remove the front panel
- Remove the bolts holding the front part of the side panel

I believe the official instructions have you remove the side panel entirely. I found that removing the bolts at the front allowed me to flex it enough to get the battery out.

Taking the battery in for testing will cost a little time but could potentially save a lot of money.

Make sure you replace the battery with the exact same Group Number. I deviated with mine and was lucky that I could make it work.

This has happened to me twice over the years. Press down on the peddle and a 2-3 second pause usually means your battery is going dead.... I ignored this and was stranded twice, Kart Aid to the rescue.

I agree, probably a bad battery, there are 2 bolts, one toward the front of the cart that you will need a long extension on your ratchet to get it out and one towards the back, these will release the barrier enough the get the battery out. NOTE the position of the positive and negative battery posts. Got to your local automotive battery supplier, have the battery tested, and get a new battery. Note some store have 1, 2, and 3 year warranty batteries, I typically get the 3 year warranty. When you reinstall the new battery make sure the battery posts are in the correct locations.
On a side note some Yamaha golf carts do not charge the batteries correctly there is a post in the DIY area to fix this, and many of the Stryker units were wired to be constantly ON which causes a significant drain on the battery. There is a fix for this that changes the power supply connection from the normally ON to the SWITCHED supply from the ignition (master) switch. This means you may have a 30 second delay until the unit is up and running.

Kart Aid can also replace your battery. They came to my home last year. Reasonable price.
