Battery OEM Mazda or Deka

I'm running a Deka ETX 14 and us a battery tender jr. works great

I had the ETX14 in my N/A R32 for over 2 years and only time it really drains down is short starts and stops from the afterrun coolant pumps running for 5 minutes.

I have the DEKA ETX20L it started my car in 15 degree weather... I leave the car off for 3 days out of the week and it starts right up... I've been using it daily for quite a while... it has died on me a few times but it was my fault for leaving the fan on.. I just recharged it and it has been fine.

just had a etx14 sat in car for over a month and started right up.

Prep the car... Prep the space... The new beatzzz Deka Batteries... Clean as can be! Hot damn clean wiring!

forget optima. Go with a Deka.

Deka. cranks every time

Battery died less than 12000 miles. Apparently Mazda is using cheap batteries, as this seems to be a common issue. But I still see others complain about the same thing.

first issue I had was the battery at around 2000 miles, it was replaced under warranty.

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