I had bought a 42 month maintenance free battery back in March of 2019. On Friday the 4th of December 2020, the battery did not start my Jeep. I called Belden to inform them I need a battery to replace my dead one. The called me back in about 2 hours and informed me that they would have a battery on Monday morning. Great ! While I waited the weekend, I troubled shot all of the electrical solutions, including charging the battery first with a jump from my truck and then with an over night charger. After 36 hours of charging the battery, it did not hold the charge. So we had another Eggnog and watched Hallmark Christmas Specials while decorating our home ! Monday came, I picked up the battery, brought it home , installed it and poof everything is perfect as it should be. Thanks Belden ! Merry Christmas and to all a good night !
