Battery Comparison - Flooded vs AGM

Hi, my name is Matthew Sauer with Canadian Energy, and today I'm going to talk about the difference between an AGM or Absorbed Glass Mat and our standard traditional flooded lead-acid product offering.

In the standard flooded lead-acid battery, a liquid electrolyte fills up in the entire cell, whereas in AGM, there is no loose liquid. Everything is absorbed into a glass mat. So, if you tip an AGM battery completely on its side, no liquid would come out. Whereas if you were to tip a flooded battery on its side, electrolyte would run out of the vent. AGM tends to hold up better in cyclical applications, whereas a flooded lead-acid battery is more beneficial in starting applications.

An AGM battery can be three to four times more expensive than its equivalent flooded lead-acid battery. So, not only does it come down to performance when choosing between a flooded or an AGM, but it also comes down to cost and budget.

If you are running on a tighter budget or don't see the benefit in having an AGM battery in your vehicle, you can go with Canada Proof MIXTECH. With the mixing technology, we see extended life comparable to that of a traditional lead-acid battery at half the cost of an AGM.

If your vehicle has the starting battery in the trunk or inside the cab underneath the driver's seat or passenger seat, you will want to go with an AGM battery because it does not off-gas. Whereas if your battery is just underneath the hood of your car, a standard flooded lead-acid battery would suffice.

There are pros and cons to both types of batteries. With AGM, you do not want to increase over 14.4 volts because that increases the internal heat of the battery. An AGM battery is susceptible to drying out under extremely high heat, whereas flooded batteries can handle up to 14.7 volts.
