Battery OEM Mazda or Bosch

Alright so i picked up a bosch 750 cca battery and threw that in her on another -10 F day, cycled the glow plugs once and she fired up like it was a mid summer day. Hasnt given me any trouble since and its been nothing but cold here.

I'm using a Bosch Group 48 battery (it is 26 months old now) from Pep-boys. Their testing machine result says 'good battery' The guy at the store said, it was as good as a new one.

new bosch battery

Bosch Battery from Pep Boys 80 Bucks with a 20 dollar rebate. OEM fit.

I've done all the scheduled maintenance on the car over the last 6 months including: Bosch S5 Battery

The best replacement battery i use in all my Vw's and other cars and trucks is Bosch..They are usually right over 100 bux but the are dependable, They also come with a 7 year warrenty.

I bought a Bosch for my car. Size 47. 600CCA at 0F, 750 at 32F (Part # S5531B) It's starts the car fine, but if the car has been sitting in the deep cold for 2 days.... it cranks a bit slow.

Bosch batteries are no poorly made in china

So far have not had any issues except for dud OEM battery, kriginal and warranty...

I've been seeing the same issue with batteries branded under Bosch and Champion. On several cars, I rarely had to replace batteries, now it seems like it is a 1-2 year thing on any battery. They are dying faster without ability to recharge. I just posted in the Scirocco forums that my 3 year warrantied Bosch battery is no longer holding a charge and its not even 11 months since I bought it. Glad to know that I'm not alone in seeing that engineered battery obsolescence seems to have arrived.
