After experiencing multiple; premature battery failures, boosted batteries, spilled acid clean ups, corroded battery connectors and short battery life I started researching if there was something better out there. The great news is I’m coming up on 4 years of trying something better and my new experience has been fantastic. I thought it was time to share the secret to fellow off roaders!
The battery technology is called Absorbed Glass Mat or AGM. Its a great alternative to the traditional wet cell, lead acid or flooded batteries that most of our vehicles are coming factory equipped with. There are benefits to Flooded batteries for some applications, and price is the only advantage that I can see. This is a great example of you get what you pay for.

They describe overlanding as self-reliant travel to remote destinations. When nothing on my truck will work without a battery, I find one or two AGM batteries is a great investment!

Here is a list of why I love my AGM battery!
1. Longer reserve capacity
-With out my vehicle running I can run my lighting, electrical accessories or stereo around the camp longer.
2. Vibrant resistant nature
-My rough road driving no longer shortens my battery life.
3. Slower self discharge rate
-If you are to park your vehicle for a long period of time flooded batteries can loose approximately 1% of its charge every day.
4. No corrosive gas or liquid
-You could mount a battery or second battery inside the cab of your vehicle and corroded battery posts are a thing of the past.
5. Maintenance free
-Win, no more corroded battery terminals!
6. Can be mounted in any orientation
-Also means no acid spilling when driving up or down steep grades.
7. Faster charging rate
-most AGM batteries can charge 5 times faster than flooded batteries.
8. Safety
-In the situation of an accident a lead acid battery can leak acid or even explode.
9. Battery Cycling
-Less damage is done or life is lost when cycling your AGM battery from full charge to discharged. Lead acid batteries are intended to run all the time at full or near full charge.
I love the dual battery set up as you can set the system up to always have a full starting battery and a designated accessory battery. Simply said, you could double all the advantages found above!
