I've switched to Interstate, as vehicle batteries fail...still have a conglomeration of JD, SEARS, and Private label in the rest of the vehicles and tractors...
2000 Chevy 2500, primary emergency response, have had the battery run down twice on emergency scenes, where someone was so kind to shut off the motor but not the light bar...

Jumped to start on scenes and recharged both times at home and is still starting the beast as of today...when the temp was 13 degrees F...
87 Ford dump truck sat for 6 months and fired right up and that was at 18 degrees F earlier this morning...
70's something backup 2640 JD, also sat for over 6 months and fired right up, but the temperature was warmer...

Finally, had the JD battery in an 855, which I had to replace in the spring twice, since it's been an Interstate...no problem...
But as the saying goes...YMMV...
