Battery Panasonic or Deka

As a harley tech I see more aftermarket batteries fail then I see oem ones fail. There are a few good aftermarkets like DEKA but for the most part aftermarket batteries seem to fail quicker then oem.

My 2019 Mazda 3 died on me randomly a couple months ago. The dealership ran a test on it and it came out fine. I changed it anyway as it was a stock 5 year old battery. It’s been fine since, even in the -20°C temps where I am.

I just replaced the battery on my eco drive from maybe 2008ish? Battery itself was 14 bucks on ebay, oem brand(Panasonic). Swap took 5 minutes.

Deka. Solid battery.

My Mechanic had me get non-AGM style from Deka. I have the dual battery setup, and have drained my spare a few times already and it’s out performed the previous brands.

My original Panasonic lasted seven years in my car when new

After the original battery, i replaced it with a Panasonic battery (nasa ₱5k that time) in 4th quarter of 2019. Etong panasonic battery life, last June 2024 ko lang napalitan (after 4 to 4.5yrs of service )????

Out of stock yung Panasonic so pinagtyagaan ko nalang yung Motolite priced at ₱7k recently (shucks i hope this battery lasts kahit 2yrs).

I really like the Deka ETX12. Point is these batteries are bulletproof. They last longer than any other battery I have ever gotten. I highly recommend them.

Just use a Deka ETX20L. I think they're 15 pounds or so and they're cheap and widely available. Mine seem to last about 2-3 years, although they usually die from me forgetting to turn the headlights off. I was able to recharge my last one using a wall charger and I squeezed another 6 months out of it before finally replacing it.

They use some crap Panasonic battery.
