AGM Mounting positions

When I said 'close to what I was thinking' I just meant the position of the battery. Can you mount one that way in a box? Also, is there anywhere to get a copy of ABYC standards without paying a ridiculous amount?

The previous batteries were wet cells stuffed in a compartment (not 'mounted' at all), with a charger set for AGM batteries, and the previous owner had never added any water to them! They had to go! The electrical system was the most ridiculous and dangerous rats nest of wiring I'd ever seen. It was scary! I ripped out all the old wiring and built a new panel. I'm now working on rewiring with the correct cable to the correct points with properly cared for batteries. And some upgrades while I'm at it!

Nothing supporting the weight. The cheap plastic strap holding the battery in place had torn free and it wouldn't take much of a bump for the battery terminals to contact the inverter ....... BANG !

Neither AGM nor GEL's are exempt from ABYC battery installation standards which although not mandatory make a lot of sense. eg. batteries much be in a box or tray resistant to spilled electrolyte. Even AGM's can split .....

AGM Mounting positions

I got some rather large (Group 8D) AGM batteries for a song. I'm re-wiring the whole boat, which allows me to put them wherever I want and their size won't allow me to put them where the old ones were. Just wanted to see what my options were.

We have two of our 6 6Volt AGM on their side with no problem over 5 years now. No difficulties

I have them installed on their side. No complaints.

Re: AGM Mounting positions

Not on a cruising boat, but I saw a rack of them installed SoR a solar array where they were stacked on their side with the 'top' facing out. This was so all the connections were easy to service and inspect.

They worked fine, though I have doubts about AGM's for solar as well as on a boat.

Re: AGM Mounting positions

Upside down is good :-)

Seriously, you can install them in any position you like. I suppose the most used position other than upright is lying on their side.

Why do you wanna install AGM's on that Cheoy Lee, anyway? All too often, they're the WORST option for a cruising vessel.
