My old boss, at an automotive shop, swears by interstate.
Im the boss at my shop and I swear at Optima.
Even Optima Jim cant defend thier POS enough on the net.
Im a firm believer in good ol lead plate acid batteries. They cost me $20 at the wrecking yard.
I dont care what brand they are. I do know one thing tho, I disregard the brand and put the tester on them. The test/tester is supposed to be for 10 seconds (dead short while metered). I hold it for 20. At about 12-15 seconds the **** batteries will drop off fast and not come back up. On the good ones it will drop a bit, then level out and maintain. Thats the one I buy.
The kirkland, interstate, and les schwab truck/4x4 ones seem to test the best.
And PS, if anyone goes to a wrecking yard as per my advice, DONT got to pick and pull and expect to get anything worth a ****.
Go to ta modern wrecking yard that buys NEW cars and trucks owned by people that just bought a new/quality battery.
At the shitty pick and pull and 2 bit yards they will only have POS rigs/baterries.
With quailty batteries lasting 5-7 years, I have no problem with someone else charging my battery for me for 1-2 years beofre I get it. :redneck:
