Need Advice On Non Golf Cart 12V Batteries
I have a houseboat on a lake and the batteries are getting old age wise. The "house" battery that is a 27 size deep cycle is 8 years old. The two smaller batteries for the two V-8 engines are a bit newer and are deep cycle also since they are wired to bilge pumps.
I don't have anyway to performance test these and I would just like to replace them for peace of mind. I haven't bought batteries for many years. My options are Autozone, Advance Auto, NAPA and Costco. And there is a marine dealer near the lake that carries Interstate. I realize that this is a non-golf cart post but I really appreciate the battery expertise for batteries here. So, my basic question is are any of these brands better than other or a better bang for the buck? |

And if you're looking for cheap, Rural King (if there's one near you, I know it isn't among your listed options) has cheap batteries. You get what you pay for though.

Re: Need Advice On Non Golf Cart 12V Batteries
I don't have a lot of input on brands of batteries but I did want to say that you can test all three batteries with what you have on hand (as long as you have a DVM). In my opinion the best way to check a battery is to run it under the load it will normally see. For you house battery turn on everything you can and max out its load while monitoring voltage, if it holds the load and keeps 12plus to 11.9 under load volts it might be fine for another few years. Your motor batteries can be tested in a similar fashion, read the lowest voltage while cranking the motor, if they hold 11 to 11.9 they might be good to go.
With that said, I will repurpose batteries that are critical for operation such as your boat batteries. If I put a new battery in the boat and the old one has some life left, it might get gate opener duty for several more years, or take a new home as an auxiliary battery in a cart. If you want to replace them for peace of mind by all means get some fresh lead. Two of the oldest cart batteries I have are serving auxiliary battery duty and doing it well. |

I may be mistaken, but I believe all of the brands you listed are made in Mexico by Johnson controls. Compare specs and buy the least expensive one.

In addition to what I listed I also have Walmart and Tractor Supply as possible sources.

Re: Need Advice On Non Golf Cart 12V Batteries
BCI size is just the case dimensions (Width, Length and Height), which has little to do with AH capacity other than only so much lead can be packed in a certain sized box.
I'd get the heaviest batteries that would fit is the space available. (Heavier = higher storage capacity) You probably want true a deep cycle battery for the hotel load and marine batteries for the ones that start the engines and run the bilge pumps. Highest storage capacity (AH) at the lowest price from a local vendor tends to be the best bang for the buck. ------------- FWIW: I special ordered my Exide batteries through a local farm supply (Rural King).
