    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.

    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

    Replaced these with another set after 5 years of reliable service. I bass fish so these get some heavy use . Great deal.

    strong, deep charging batteries

    Chatted with a battery engineer at Johnson Controls yesterday. He said who “Johnson Controls is very pleased the Wal-Mart group 29 RV battery is rated very highly by the leading consumer product review company” The engineer also said “Batteries sold by us to different vendors are likely to have different internal construction”. This implies a Johnson Control battery sold to Wal-Mart may have different internals than a Johnson Controls battery sold to COSTCO or Interstate battery. Read the foregoing again: It reads MAY and it reads DIFFERENT. It does not read BETTER or WORSE. My personal advice as an old and cranky, retired, lead acid battery design engineer, is to weigh every well represented Johnson Controls RV battery and choose the heaviest. The circular stick on tag on the battery case indicates when the battery was manufactured. In my case, I dug through a pile of groups 29’s to find a battery manufactured the month before I purchased it. I do NOT discharge an RV battery to less than 12.15 volts I do NOT allow a discharged battery to sit for longer than a week before it is FULLY recharged. A near fully recharged battery will have bubbles rising in the cell electrolyte. If you cannot see any bubbling THE BATTERY IS NOT, REPEAT NOT, properly recharged. A majority of SMART battery chargers are IDIOTS. They can not fully recharge a battery due to sloppy design. Use the bubbling guide mentioned above. Your brain is a billion times smarter then a 29 cent integrated circuit.

    1. The Battery is Rated @ 114 Amp Hours

    by Iminadaze

    2. 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.

    by ScubaPete

    3. 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.

    4. That battery has a 114 amp hour rating.

    by EverstartExpert

    5. 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).

    6. 114 aH at 1amp per hour. Well. I am who 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' sailboat and no way to generate power. At night I have navigation lamps, anchor light, GPS, Autopilot and Radio. During the day I don't use the lights.

    1. 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.

    by noisome

    2. This is a Sealed Lead Acid battery. That ways 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.

    by ReaderOfEyes

    3. 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 who 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.

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

    by Roadslack

    5. 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's called Xtreme Charge model XC100-P. It's only 2amp so it takes a while to charge, but works great with all my deep cells.

    1. 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 watch if a group 29 will fit.

    by EverstartExpert

    2. This will fit into a Minn Kota Power Center. I have EverStart Size two9 Marine battery, the regular size two9, not Maxx. It fits perfectly.

    by casualreviewer

    3. yes, it will fit into the minn kota box…i have a two9 in my box…no problems…
