    08 Hyundai Elantra

    Customer review by biketrail

    5.0 stars by biketrail

    Hyundai has a particular battery size for their vehicles. The manufacture group size for 07-10 Hyundai Elantra's are 121R with 550 CCA. Thanks to Walmart they carry this group size for $40 less than any other auto parts store for the same battery size but at least Walmart provide better warranty. 3 years FREE replacement compared with 24 months from any other retailer like AutoZone, Advance Auto parts or Interstate Battery. In the market the only retail that carry Hyundai group size are Advance Auto Parts and Interstate Battery, any other retailers just want to give you a similar battery size with similar specs. This battery came with 50 CCA more than the factory one, it is very close to the OEM battery size, the only difference is the with, this battery it is about 1/2 of inch narrow than the OEM, but the other dimensions are the same, the base size where the battery gets screw it is the same OEM size. So, for an aftermarket replacement it is right on the money and for $89.95 for 3 yrs warranty there is no brain here.

    I have a Hyundai automobile with an electronic security system. The system relies on the car battery to funciton. I can only enter the driver door with a key because the other doors are electronically opened. My first battery needed to be replaced after two years. This model battery at walmart is the most expensive battery offered at Walmart that fits into my car. I hope it lasts a long time. At first glance it functions admirably. I bought this battery primarily because Walmart honors warranties religiously. I know that if this battery fails, Walmart will replace immediately with no questions asked. The warranty is for three years. I probably will collect on the warranty. Thank you very much Walmart for selling a product with reputation and reliability behind it.

    Fits Kohler 12RES Stanby Generator perfectly

    Customer review by WirelessMike

    5.0 stars by WirelessMike

    The Koher 12RES standby generator specifies a battery with 650 CCA. While the Maxx-121R falls just a bit short with 600 CCA at 0F; it fits well in the space available in the cabinet. You only have about 9.25"w x 7"d x 9"h to work with. This is the most powerful, commonly available battery I could find that fits and comes close to delivering the specified starting current. It starts the generator quickly. That said, the Maxx-121R did replace an older Group-26 size battery which was only rated for 525 CCA. It did just fine in the coldest conditions for seven years, so the higher CCA on the Maxx-121R is just icing on the cake. (The old one was still working, but figured after 7 years it was time to replace before it died at a really bad time.) Coincidentally, the two are nearly the same size. The other thing I like about this battery is you can open the caps and add water. Most home standby generators have a battery charger attached all the time (they should anyway). Over the course of a few years, some water is going to boil off. It's easy enough to pop the caps off every year or two and add a little distilled water to get the longest service life possible.
