Everstart Battery — bad cell

We purchased a battery at walmarts, to replace a seven year old battery, we continued to have car problems thinking that it must be something else as we had just purchased a new battery, after putting in a new starter and alternator and license mechanic checking it out it was discovered that the new battery that we had purchased was bad. This little adventure cost us a lot of money for the simple solution of a bad battery bought off the shelf of walmart.
