Battery Panasonic or Deka

Original factory Panasonic battery in my RX-8 lasted 7 years. The 'premium' Exide I replaced it with is on it's way out now after only 4 years.

When I bought my 2006 4Runner V8 three weeks ago, it had the original Panasonic battery on it's last leg and I had it replaced with a Toyota True Start battery. The 4Runner only had 109,600 miles when we had that battery replaced.

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.

I have some extended experience with a lightweight battery in my daily driven 2006 Boxster S, which is well known for the demands it places on the battery. In spite of that, I successfully used the Deka ETX30L (21 lbs.) for almost 3.5 years.

Switched to a stock mk5 4cyl battery though as the Deka couldn't handle sitting for more than a couple days without being on a trickle charger.
