If you are operating your battery packs in extreme temperatures, that places a high level of wear on the battery cells. This may not seem like something that happens that often until you realize just how hot it can get in a car with the windows up during summer.
Great dialogue about appointment time and I was kept up to date at all times. I was made aware of cost before work was done. Work was do well and in a timely fashion.

The replaced battery is entitled to an additional 90 days warranty starting from the collection date. The warranty does not cover damage resulting from mishandling/human induced damage.
Step 3: Once you do that, you can check each cell group’s voltage to make sure they are all within range. If any of them are less than 2.5 volts or so, that group is probably bad. If you find a bad cell group, you are going to have to break the welds loose and remove those cells. It’s important to replace the bad cell or cell group with cells that are of similar capacity to the ones in the rest of the battery pack.
