    Great Battery, But Check The Electrolyte First

    Customer review by Roadslack

    5.0 stars by Roadslack

    Be sure to check the electrolyte level when you purchase the battery. I purchaced the MAXX DC 29 and MAXX DC 24. Both had low electrolyte levels. While there was sufficient levels to keep the plates covered so sulfation wasn't a concern, I had to add 6 - 8 oz of distilled water to each battery to get both battries to the proper levels. Also, make sure you purchase the newest battery you can based on the date sticker on the battery. Most experts recommend you don't by a battery that is older than 3 months old. The two batteries I purchased were less than a month old. While the battery says maintenance free, you will need to monitor the electrolyte levels if you want your purchase to last.

    This Battery Is Manufactured By JOHNSON CONTROLS

    Customer review by elcodo

    5.0 stars by elcodo

    Chatted with a battery engineer at Johnson Controls yesterday. He said that "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.

    The new maxx29 not the same as the old maxx29

    Customer review by Dgoffe

    3.0 stars by Dgoffe

    Three to four years ago the changed the spec on these batteries. They use to weigh 66 lbs and now weigh 61 lbs. to keep the price down they took away 5 lbs of lead and it really shows. I tried interstate battery and they have the capacity of the old maxx but I only got three years out of them. Please bring back the old 125AH battery and call it something different MaxxDCP 29. With the P standing for plus. Most people that need a 29 size battery need the BEST battery they can get. The difference in price doesn't matter.

    • A. 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).

    • A. 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.

    • A. 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.

    I am trying to determine which "Battery Tender" or "Floater" product to buy and I cannot determine if this new battery is a GEL battery or not. I can not determine if this battery is even a real "Deep Cycling" battery or not? Any recommendations?

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

    • A. 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.

    • A. 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.

    • A. 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.
