"AGM Car" batteries for less used tractors?

What about spillage?

What about ''sealed" regular acid batteries made? Maybe this is an option? They can't gas-off and I never had one leak or corrode anything.

Before I switched to AGM's, I used sealed batteries and still would if I could find them.

SLA's are still vented (look at the cap assembly). They have a molded into the cap series of chambers that allow the gassing off to condense and return to the cells but are still vented. If they weren't the case would rupture in the event of severe gassing off.

I'm not familiar enough with the material to know if battery acid soaks into it.

Good reading the various points about AGM and FLA. I need to replace my Kioti battery, I had stuck a newer trolling motor battery in it for a quick start a couple of months ago. I am thinking I will go with an AGM as I hate the extra work of corrosion. Gonna top the terminals off with some white lithium grease for good measure.

I use AGM in my boat for the trolling motors (different trolling motor battery than above), wasn't too pleased with the BPro brand they lasted about 4 years I think it was. Interstate's seem to have lasted the longest for me.

How long any flooded cell battery lasts depends a lot on how long it sat before you purchased it actually. Once a wet charged battery has electrolyte added, it's on it's way to being obsolete.

Trick my daddy taught me: Glue a couple of copper pennies to the battery adjacent to the terminals. They are more reactive than the terminals and clamps and will corrode first.

I was putting a new battery in mom's Volvo, and had bought a pair of the felt washers the parts houses sell. I was putting in and dad came out and asked what the felt washers were for. I told him and he asked how much they cost. When I told him, he laughed, and said next time save $1.48. He proceeded to glue two pennies to the battery and explain the chemistry.

Sure enough the pennies corroded, but the terminals were clean. Every time I did a tune-up, I'd pop off the corroded pennies and install new ones.

The pennies act as a sacrificial anode.

for more than 40 years (since 1982) pennies have been made of Zinc (97.5%) with a thin Copper plating (2.5%). Prior to 1982 (back until the 1860s) pennies were 95% copper.

I've used AGM since they first came out and never a terminal issue. You could skip the grease on the terminals.
