i moved my battery under the passenger headlight. i noticed that there was rust forming from the battery acid on my battery box and horn. i need a new battery anyway, and i want one that absolutely won't leak. Do i need to spend for an AGM or is a sealed lead acid battery leakproof?

thanks

No battery is "Leak Proof" but AGM units are much more leak resistance then any Wet types.

AGM, unlike "Jell Cells," uses same liquid electrolyte as wet but absorbed by "sponges."

They don't make a JCell for automotive use.

⚠️Warning: Leaking battery is often a Symptom and if you don't find the real root cause then a new battery of either type won't last long.

How long did it take for the rust to form? I also moved my battery up front under P-side headlight about a year ago. I built my box out of aluminum so it wouldn't rust and I painted the surrounding body metal in that area with rust-preventive paint. No sign of rust anywhere yet. I'm also keeping an eye on the wire harness in that area for corrosion at the terminals.

I use AGM batteries and they last longer and do not leak. As a matter of fact Optima says its AGM batteries can be mounted upside down, I read Optima's quality (now 100% made n Mexico) has fallen so I'll be checking out other brands of AGM batteries to use next time

So what BCI group number batteries do you guys use that are available in AGM? The 84 is speced as a 70 and the rest are 75 BCI group number. Who makes a 75 group number AGM?

Odyssey makes a Group 75 AGM battery, I have one in my Mera. I have used Odyssey batteries in several cars and motorcycles with excellent results. They all lasted at least 6 years or longer and no leakage. I charge them once a month if the vehicle isn't driven frequently with an Odyssey brand charger.

Interstate MTZ-75DT is a great AGM battery with a great warranty.

I'm happy with my Optimas Red Tops in both of our Fieros.

Since OP is in NS, it might be worth checking Canadian Tire. We're running their Motomaster AGM battery in my wife's Hyindai Accent, and have been pretty happy with it. Not sure if they make the correct group though (considering you relocated the battery, I'm not sure you're running the same group in the first place).

i have 9 inches and change in my battery box. The original batteries for the duke and V6 85-88 will fit. So will the 84 duke battery, but it has a LOT few CCAs
