Battery OEM Nissan or Deka

OEM for Harley. I've replaced several with an average lifespan of 5 yrs at 20%+ cheaper than Harley branded

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.

I quick charged my Leaf over 350 times in 2 years and it barely degraded the battery.

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.

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.

We had a 2015 Nissan Leaf EV back in 2018. Fun little car but it only has an 80 mile range.

I have a 2018. purchased in april of 2021. the previous owner had replaced the battery about 6 months prior to me buying the car, within 6 months, the replacement battery (nissan OEM) died. in november 2021 i got new battery from autozone, and it lasted just 3 years.

Shop Forman and Nissan tech of 15 years, lately we have seen a ton of frontiers come in for battery discharging. Some will be batteries that do test bad, some have been discharging for no reason even after confirming no parasitic drains, some believe the Telematics control unit is staying on/relaying to Nissan servers causing drains. With the variable charging systems controlled by the ECM/IPDM all of it just seems to be a recipe for electrical disaster. Not a fan of any of it

Bought a 2025 Rogue Platinum less than 2 weeks ago. So far, on day 4 the car was completely dead in my driveway. Needed the battery replaced.
