For many years i have run Walmart Batteries in my bass boat, using from one to four depending on the boat. They were relatively inexpensive, you could trade them almost anywhere if you had problems, and I could get from two to two and one half years service from them.
My current boat, a Skeeter ZX 225, has a cranking battery, a batter for accessories like deptfinders and aerators, and two trolling motor batteries for the 24 volt Motor Guide trolling motor. I started using a different battery for accessories a few years ago when my boqt would not crank, the aerators had been running all day and I had stayed in one creek all day. I vowed that would never happen again.
In November my two Walmart Batteries were drained the first day of a Top Six tournament on a very windy day. That night a windstorm blew a tree down on the power lines going to my campsite so my batteries didn’t get fully charged. I was dead in the water by 9:00 the next morning. Since the batteries were about 30 months old, and I usually got from 24 to 30 months from Walmart batteries, I replaced them and the third battery too.
By the first tournament this year, only 13 months later, those two batteries would not hold a charge for more than half an eight hour tournament day. I took them in but they tested ok. They would hold a charge but were useless for a trolling motor used all day.
Even worse, last fall, less than a year after putting a new Walmart battery in for accessories, it started falling after about six hours. It was running an HDS 8 unit up front and an HDS 10 on the console and most of the day the console unit was on standby. Both aerators were also running. Again I took it in and it tested ok – and it will hold enough of a charge to use as a cranking battery in my Ford 1510 tractor.
I knew better but got another Walmart Battery for the accessories in November. In February it would not hold a charge for an eight hour tournament day running just two depthfinders and two areators. i had to use jumper cables to keep aerators running until the end of the day. Early in March I would fish all day in the wind at Eufaula. When I came in the two Exide Batteries I put in this January would be down to 90 percent charge. After a couple of hours they would be at 100 percent and still be at 100 percent the next morning.
The five month old Walmart battery would be down around 50 percent when I came in, the point where the depthfinders started failing. It would charge back to 100 percent overnight with my three bank on board charger and a stand alone charger hooked to it. But an hour later, after taking the stand alone charger off, it would drop to only 80 percent.
I put another Excide battery in today for accories! I will never buy another Walmart Battery.
