I agree with Iminadaze, in the store today (5/11/2012) this battery is now rated at 114aH @ 1A. The date of manufacture was 3/12.
Previous answers had this at 125aH.

Looking at the spec sheet, which there is none, it's not possible at answer your question. Most manufactures will state Amp/hours for a 20hr period of discharge time. As the load/current is increased it will decrease the time it takes to reach 10.5 volts which is considered a dead battery. That is common sense; the more you drain it the faster is dies. What is important to know is how this affects the amp/hour rating. A battery that is discharge over a 2 hour period may have a rating of only 68 amp/hours. That same battery discharged over the normal/standard 20 hour period of time may have an amp/hour rating of 100. If left to discharge slowly over a 100 hour period of time it amp/hours may be 118. So when a manufacture states an amp/hour, they should also state the time period of discharge. Brand name batteries usally have a spec sheet list the various amp/hours versus the time period. Doing it that way gives the consumer something to compare when buying a battery.

What mandm1200 said is right on target. But the problem with the amp hour rating on this battery (I saw it in the store today - 114 amp hours @ 1 amp rate) is determining the amp hour capacity at the 1 amp rate is highly deceptive. Most deep cycle batteries I've ever seen were rated at the 20 hour rate - which would produce a number much smaller than 114 if it were run on this battery. At 1 amp of load this battery should last 114 hours until the battery is down to 10.5 volts (that's what that rating means). But who discharges their deep cycle battery at 1 amp per hour? Nobody I know. And using a different methodology to determine amp hour rating means you cannot compare it with another battery that had its capacity determined by the 20 hour rate. It's not a level playing field. If the amp hour capacity of this battery had been determined using the 20 hour rate it would have had to have been discharged at probably somewhere between 5 and 6 amps, not one. And that would have produced a lower amp hour number, probably in the mid 90s somewhere. So beware, for all practical purposes this is not a 114 amp hour battery unless you really are going to discharge it at 1 amp (that's less than the power it takes to run one of those little incandescent RV light bulbs).

114 aH at 1amp per hour.  Well. I am that guy who pulls one amp per hour and I need this or a pair on a switch to last 3-4 days. I have a 26&#39; sailboat and no way to generate power.  At night I have navigation lamps, anchor light, GPS, Autopilot and Radio. During the day I don&#39;t use the lights.

What is the Amp Hour rating of this battery?

Its a flooded battery. This is closer to a dual-type battery, mix between starting and deep-cycle.

Product to buy to charge your battery is up to you.. The more you spend the better. Battery desulfating or "pulse" charger is best.

This is a Sealed Lead Acid battery. That means it is a wet cell battery, not a gel battery. You won't touch a gel battery for this price.
As far as I know, the only TRUE deep cycling batteries are 6V types, as used in golf carts or personal mobility devices. However, as far as this type of battery goes, it will handle repeated deep cyclings.
It has 122 Amp Hours of reserve power.

This battery is not a Gel Cell battery. It's a "flooded lead acid" battery. This battery type generally falls into two classes: "starting" and "deep cycle".

The difference between the two is the construction of the lead plates. The amount of amps that can be pulled is proportional to the surface area of those plates. On a starting battery, many holes are put into the plates to increase surface area (and cranking amps). A deep cycle battery has solid plates without holes.

When a lead acid battery discharges, lead sulfate collects on those plates. The deeper the discharge, the more lead sulfate. The solid plates in a deep cycle battery can handle a lot of that lead sulfate buildup and then shed it all off when recharged. When a starting battery does a deep discharge, the lead sulfate can plug up those holes permanently. That reduces its ability to take a charge and to provide high current, like starting an engine.

This battery, and any labeled Marine, RV, or Group 24, Group 27, or Group 29 are all the deep cycle type.

This is a flooded-cell, deep cycle battery. It is not a GEL.

Like others have said this is a flooded battery. The tender I use combats the sulfation issue and has kept mine running great for over 5 years. It&#39;s called Xtreme Charge model XC100-P. It&#39;s only 2amp so it takes a while to charge, but works great with all my deep cells.

Good morning. I do not have information on the Minn Kota set up, but this is a standard size battery. I would check the owners manual to see if a group 29 will fit.

This will fit into a Minn Kota Power Center. I have EverStart Size 29 Marine battery, the regular size 29, not Maxx. It fits perfectly.

yes, it will fit into the minn kota box...i have a 29 in my box...no problems...

will this EverStart Maxx Group Size 29 Marine Battery fit a minn kota trolling motor power center. It measures very close.

These batteries are a BEAST. Easily 1 1/2 times the size of a normal battery, so make sure you have room. The power though, WOW! You can run a trolling motor and all your boat accessories all day long off of these and they're still going to get you home. I couldn't be more pleased.

Maximum power, maximum hours of usage

Happy with things. Seems to have the power I needed and good warranty. Better than I found at other places and the price was good. Those two things made my decision to go with Walmart

Good product

Doesn't matter these are inexpensive, they are simply great deep charge batteries for boats.  I have two of them in my Catalina 30 and the only reason I only got 4 years out of them is because my bilge switch which I had dangling in a temporary installation fell into the bilge water and ran the batteries to nothing. Even then I was able to charge one of the batteries to 13.5 volts and it is useable. the other one can't be charged beyond 12 volts. Otherwise, they were performing like new right up until that accident due to a severe wind storm rocking the boat. I promptly purchased a replacement battery and got the bilge pump all worked out.

Great deep charge marine battery.

I have a 36V trolling motor set up and needed a new battery fast. So I ordered this one l. I was supposed to get same day pick up but it took 2 days to receive.  I never got an update telling me it was ready. As far as that battery goes it is OK. It doesn't hold a charge as well as my interstate batteries but it's doing ok. For $100.00 it should work for a while. I will not be buying another one of these however.

Quick fix

The order I had placed at the freehold location was cheaper than east windsor

Purchased replacement Marine deep Cycle battery on line delivered to my residence.  I was billed the customary $12.00 core charge.  Later returned old Walmart battery back to store where noone at store knew how to refund my core charge.  Spoke with 5 different people over a 30 minute “waste of time” with no results.  Was asked to call their 800 C/S %23 for assistance.  Spent 35 minutes on phone speaking with two individuals.  Final outcome, NO REFUND.
They are claiming it is a Government Tax and it is now up to their Corporate Tax department to grant the refund.  ???? WOW!  Shop elsewhere for your battery or bring in your core when you purchase the new battery.

BUYERS BEWARE

DOA x2 won't hold charge
Bought 2 for an RV.  Turned out both were dead, trickle charged both, neither charged over 50%.

Dead and won't charge, garbage

This battery is one year old. I would have liked to have gotten a newer battery for this price typically a battery for an RV as this is for less about two years so now it's half-life is over. I am going to call the store and I would like to get a return and a fresh battery I hope you can help Specifically I signed up for home delivery for someone to help me with this battery and now I find it out of date and I'm very dissatisfied

Old battery

3 days late , I guess you think we had nothing else to do but wait on a delivery that was supposed to happen before the holiday.  Very poor service

Had to get a battery else were for the need

Your on line advertising states that the Ever Start 29DC battery when purchased on line should cost $119..87. I purchased 2 of these on March 18th. I was initially charged $281.72. I received a refund of $17.98. I expected to be charged $239.74!  Even with the $17.98 rebate there is a difference of $24.00. Perhaps someone can explain why I have not received the entire amount. I have submitted two prior request with no response from Walmart. Please contact me, photo of in line item and cost attached.
