That's kind of what I was facing. My cart is a 2010 RXV that I put new batteries in last year (in April). All winter I was watching the charge meter planning to plug in the charger when it dropped below 1/2 charge. I checked it and it was 2 needles above 1/2. I thought, "I'll check it again in 2 weeks and then probably charge it up." I checked it and the needle was all the way to empty. I couldn't get it to do anything and when I plugged the charger in I found that it wouldn't even engage. To make matters worse, the RXV's have electric brakes that lock on every time you stop the cart and when the batteries aren't charged at all the brakes stay on. Last time that happened we ended up getting it to the base of the trailer and pulling it onto the trailer with a small come-a-long. It was a job pulling it up the ramp with the brakes on. The dealer at that time said there was no way around the brakes without electricity. This time we looked on you tube and sure enough there was now a way to get them to release. We loaded it up and I took it to the dealer 1 1/2 hrs. from me.
They were able to get the batteries charged, discharged and charged again. They tested and told me the batteries were testing as almost new. I decided I was done with lead acid batteries and went to see my original dealer at New Hampton, IA. which is 3 1/2 to 4 hrs. away. They gave me a deal that was $1000 less for a 2026 than the other dealer wanted for a 2025. Also, the dealer in Iowa is giving me $4000 for my old cart and the other dealer wanted to give me $2500. The cart has a new body on it and Crager SS wheels which were fairly expensive when I bought them. It looks almost new yet.
