Battery OEM Mazda or Deka

I've been buying Deka batteries for awhile now and they have been great to me as a customer.

I just ordered a Deka EXT20L, from what ive read everyone loves it. At $87 from Lowes its worth the gamble. Its a sealed AGM battery so it can be mounted anywhere, ill be putting it under the rear seat.

I have personal experience with with both battery technology and the litium ones put the conventional small battery to shame. If I left my car with the small Deka that's in it for a few weeks without starting, or turning off the cut-off switch, the alarm and small draw I have from a wacky door switch would completely drain it.

My current dead battery is a Deka - lasted 3.5 yrs, can't complain.

Me too. Using a Deka ETX20 right now. Scooped it for $85 shipped from Tri-State Battery. I just got my car back on the road, so I haven't seen how well it holds its charge without running the car every day though.

Great thread. I have used lightweight batteries in all of my builds. Dont buy Braille or any high end BS. They are all rebranded Deka. Ended up grabbing a etx14 power sports battery from autoquest for $70. Same as the Deka ext14 just rebranded.

In sum, I can fully recommend the Deka ETX30L battery for long-term and continuous use in our cars.

My battery died last July at exactly 2,5 year mark. Mazda OEM battery is a cheap trash and so are the replacements too.

My 2014 CX-5 eats batteries and always has since i bought it brand new. I usually have to replace 1x a year\u2026 and I know it\u2019s coming about 45 days in advance because my bluetooth and USB chargers will suddenly stop working and that\u2019s how i know oh my battery will die soon!

I have the same problem with my Mazada 3. Changed the battery while still under warranty and still does it. I don't leave anything pluggeded in and it still dies overnight. I purchased a battery tender and have to hook it up every night or get a boost in the morning.
