Battery not charging

Just want to share my battery charging issue at last weekends camping trip. I selected the auto level mode and within 30 seconds everything stopped and the level unit screen shut off. I then checked the breakers and fuse panel and all was good. I had a multimeter and checked the battery, I was only getting 9 volts. The battery was 4 years old and its possible that it would not hold a charge. I purchased a new battery and installed it and the auto level worked like it should but nothing was recharging the battery according to the multimeter. I then set out to find the converter. It was located in the front storage compartment behind a panel that was held in place by screws. Once I removed the panel the converter was right there and I could see that it had a 35 amp fuse. I replace the bad fuse and the charging system was back online. The one tool I wish I had with me was a cordless screw gun. It took some time to remove the 8 panel screws.

BTW, I had the old battery tested and it would not hold a charge

Lead acid batteries don't like being discharged below 50%. I try to keep a battery tender on all my lead acid batteries that sit for a while.

Do you recall the ratings for the converter? When I designed my system, all over current protection was rated for 1.25 times the expected amperage.

I did not check the converter rating when I had the panel off.
