WK2 - New battery type and location

THE 2011 GRAND CHEROKEE USES ABSORBENT GLASS MAT (AGM) BATTERY TECHNOLOGY

An AGM battery is a sealed unit that uses special relief valves to vent vapors from the battery. The electrolyte is stored in sponge like separators consisting of matted glass filters. This suspension increases the efficiency of the charging and discharging rate of the battery. Continuous under and overcharging is detrimental to this type of battery, therefore; voltage and current regulation are critical.

Typical battery chargers ARE NOT SUITABLE as the voltage and current regulation ranges of typical battery chargers are unsafe for AGM batteries.

THE BATTERY FOR THE JEEP GRAND CHEROKEE IS LOCATED UNDER THE FRONT PASSENGER SEAT AND REMOTE JUMP-START POSTS ARE LOCATED UNDER THE HOOD TO ASSIST IN JUMP STARTING

What's supposed to be good about it?

Re: WK2 - New battery type and location

I wondered why there was a large storage area under the front seat.

High vibration and impact resistance
Higher charge efficiency allows recharging with less energy
Hermetically sealed , virtually no gassing under normal operating conditions
Can dispense charge at a higher rate

Absorbed Glass Mat (AGM) batteries are the latest step in the evolution of lead-acid batteries. Instead of using a gel, an AGM uses a fiberglass like separator to hold the electrolyte in place. The physical bond between the separator fibers, the lead plates, and the container make AGMs spill-proof and the most vibration and impact resistant lead-acid batteries available today. Even better, AGMs use almost the same voltage set-points as flooded cells and thus can be used as drop-in replacements for flooded cells.

Re: WK2 - New battery type and location

Great info! One question -- where's the air box located in the 2011 Jeep Grand Cherokee? Driver's side or passenger (still)?

Re: WK2 - New battery type and location

are these batteries only going to be available from the dealer when they fail?

I sure hope not, MSRP is $494.00 (!!!).

Also, front passenger seat has to be removed in order to pull the battery. The negative cable can be accessed and removed by moving the seat forward and removing the battery cover.

Re: WK2 - New battery type and location

Sounds like a great battery but I just wonder why locate it under the driver?

Re: WK2 - New battery type and location

Exactly, it's 2010... companies should be making things easier for us. Last time I had a battery issue I was stuck alone and had to have AAA come bail me out. They pulled my old one out, threw the new one in and I was on my way. Now I'd have to be towed to a dealer it sounds like.

Yeah, I don't like the sounds of this. Why on earth would they make it so difficult to change and at a cost of nearly $500 for the battery alone?

Well it'll make it easier to run cables for stereo systems.
