Mystery oil
 

I add a little Marvel Mystery oil to my RV fuel before I leave. Its a top engine lube that coats the upper head and cylinder. I have been using this for 40 years on all my gas engines back home. I rebuild those engines as well and know the difference.

I found a little simple trickle charger at harbor freight for 5.99 on sale.
I run several up north all winter on boats and heavy equipment, never an issue.

I do exactly this, and I use the exact trickle charger MrChip72 recommended.

Additionally, I have a pair of 4-foot long boards that are 1X12's. I slide them under the cart side-to-side, one behind the front wheels, the other in front of the rear wheels. I put the jack stands on the boards to more evenly spread the 1,000 pound weight of the golf cart across the garage's surface. A cheap 1-ton floor jack from Harbor Freight (get the one with the highest reach you can if your cart is lifted - best to get this around Black Friday sales if you can) will make this job very quick and easy.

This one does the job for my lifted cart. If you aren't getting the height you need, just put a wood block on the jack's cup to get those extra few inches.

O, please. Hit wrong key the f is right beside the g, spell check don’t recognize words that aren’t misspelled. I sure figured that. :icon_wink: I do it all the time with small key board and my shaky fingers. :shocked:.

Trickle charge
 

I have put a trickle charger on my electric golf cart with a timer set for 8 hours a day now for 9 years with no problem

Trickle Charger
 

Modern trickle chargers do not overcharge. They maintain and will preserve the battery’s life.
Alternatively, just disconnect the negative cable from the battery.

Battery maintenance charger that only charges as needed, and have it plugged into surge protection.

SeaFoam in the gas with a full tank. If you have someone that will drive it once a month that is great but not needed.

When you say "battery" are you referring to the battery on a gas powered card, 12 volt batteries wired in series in an electric cart, or a Lithium-Ion battery powered cart?

I use a battery maintainer. It does trickle charging but stops when the battery is full, then monitors the battery's charge and maintains it. This is the one I use; it's less then $30 on Amazon and easy to use:
NOCO GENIUS1, 1A Smart Car Battery Charger, 6V and 12V Automotive Charger, Battery Maintainer, Trickle Charger, Float Charger and Desulfator for Motorcycle, ATV, Lithium and Deep Cycle Batteries https://a.co/d/5elPgKq

Beware of the Harbor freight trickle charger, it fried my car battery. I found out when I replaced the battery and connected the trickle charge with my voltmeter on the battery, and hour later the battery voltage was over 15 volts. I threw this device away.

I do as well and it works great.

Agree 100%. Battery Tender has been around for years and I've never had one fail.
You get what you pay for. I wouldn't trust the cheap ones.

cart battery
 

I have 2 carts one electric and one gas. I don't use the gas cart much. To take care battery of gas cart, how often and how many miles I should drive it?

Battery tender and fuel stabilizer .

Mine has sat for six to eight weeks without a problem but I try to run it once a month.

When it was new and I was only here occasionally, it would sit at least three months. All I did then was disconnect from one of the battery terminals though I don't know if even that was necessary.
