Received this Deep Cycle battery 2 weeks ago from Amazon. The manufacture's production date was 11/2011 and the manufacture's ship date (to Amazon?) was 12/2011 so the battery was received factory fresh. It arrive with a full charge per my multi-meter at 12.8 volts. It has 840 cranking amps at 32 degrees and 700 cranking amps at 0 degrees. It is a 100 amp hour battery with a 200 minute reserve capacity.

This battery was installed in a diesel pusher motor home as the "house" battery, which is used to power the lights, heat, water pump etc. when you are not connected to utility power or running the generator.

It is heavy (at about 72 pounds) but since it is a sealed AGM (Absorbed Glass Mat) battery we won't have to remove it every 6 months and check the water level in it as you do regular lead acid batteries.

We also use a NOCO Genius G7200 charger (also sold through Amazon) to keep it charged since it is a "smart" charger and will not over charge the battery. We no longer use the coach's built in 12 volt converter/charger to keep the batteries charged since it will over charge the batteries and shorten their life.

Even though we have only had the battery 2 weeks, I would recommend it for 3 reasons:

1. PRICE! When shopping around for a group 31 AGM battery, our local battery store (Batteries Plus) wanted $325.00 for theirs. (To be fair, their AGM battery was a hybird with 1000+ cranking amps it is across between a deep cycle battery and a starting battery.) Other places online wanted $250.00 or more and around $50.00 shipping!

2. Exide has been making batteries for over 120 years so I think they will be around to honor their 2 year replacement warranty.

3. As an AGM battery there little maintenance (Just wipe it off every now and then). I have had an AGM battery in our full size truck for 7 years with no problems to report. Our other vehicles have had to have their batteries replaces every 2 to 3 years. The heat in Texas is hard on a battery... (From now on when we replace the batteries in our vehicles, they too will be AGM batteries.)

We plan on purchasing 2 more of these batteries when our existing engine starting batteries need to be replaced in the coach.

Hope this helps someone!

I bought this battery for my travel trailer and it passed the test on a recent 10-day trip to Yellowstone park. I had plenty of power for the whole trip without having to recharge. There was not a hint of fading power on the whole trip. My previous battery, which is only a year old, did not last this long on week-long trips. I'm happy.

Added 1/13/13 I bought a motor home and no longer use this on a trailer. I am now using it as a battery for my Minn-Kota 50 lb thrust troling motor on my 2 boats. I can also hook up my fish finder to it and have plenty of power for both. It works as a back-up for the motor home though I haven't had to use it yet.

I purchased two of the Exide MC-31 batteries from Amazon which were delivered in May, 2011. They were very well packaged and in excellent condition. After unpacking and inspecting the batteries, I was surprised to see that the manufacture date was May of 2010. The batteries had been in storage without charging for a full 12 months. The open circuit voltage indicated only about 75% charge, indicating that some plate sulphation must certainly have taken place by this time reducing the battery life and capacity. When I contacted Amazon their representative directed me to deal with the manufacturer. (Catch 22) The manufacturer did not supply the batteries to me directly and they were not actually defective (just old). I put the batteries into service and just hope their service life has not been shortened dramatically. When they were shipped to Amazon is not known, but selling lead acid batteries that are already a year old sounds like a huge oversite on Amazon's part. If you are considering the purchase of one of these batteries, I would suggest you contact Amazon first and inquire as to the date of manufacture.

I was a bit worried about ordering a battery from Amazon especially after the poor review and date problem listed below but, our travel trailer battery was dead and after checking local prices (whew!) decided to give this a try.

After reading all the reviews, opted for this one and then noticed, WarehouseDeals had one available for a few bucks less. Since batteries can't be returned in general, I figured the less spent, the less risk and opted to give it a go.

When the battery arrived, my initial reaction was "uh-oh" because it was dusty and dirty. No grease or anything but lots of dust...I think there was even a shoe-print on it! I dreaded the worst thinking this thing must have been sitting around the warehouse for ages. No so! I cleaned it off a bit and saw the date being the SAME month as shipped! Wow I can't even get batteries that new locally. In fact, I can't come anywhere near this price on this battery (or similar ones) locally...the next best price was about $100 more than what I paid.

Hooked it up to see the charge...was at 92%. Charged the remainder. Works like a charm! Couldn't be more pleased by this purchase. Great battery, great price, great delivery, very fresh! Oh it was dirty as all get-out but I saved about $100 so still very pleased!

Not sure why the production date of the battery I got was 12 months ago .. but it was fully charged and came packaged well enough. Since it shipped for free with Prime .. I'd hate to know what it would have cost with regular shipping cost considering its weight.
