Battery OEM Chevrolet or Deka

It wouldn't be a bad idea. But also you never know. My old car's battery lasted 8 years before I finally had to replace it. Sometimes things just chug along for a long time

The bolt (possibly the cheapest used EV available) batteries last well into the 200,000mi lifespan. My insurance lowered $80 when I bought my first EV. My state started charging an extra $150 to register an EV in 2019. About the same as the average ICE owner would pay in gas tax.

Generally speaking the ownership cost is low. I have had a 2013 Volt since new. I hardly ever need the engine to run, so it has had 6 oil changes in 12 years. I have done no other engine maintenance. It still has its original traction battery and is still performing well.

At 10 years and 330,000 kms my Volt battery didn't even show degradation.

Mine is ten years old. It's a Chevy volt so it's a small battery and has over 3000 cycles and done 130000 km. It's at 87% original capacity.

UPdate - new battery and bluetooth 12v monitor installed last Monday night, all good since then including one day with 40 miles of driving and recharging in weather well below freezing (16 to 28 F), but I happen to be mostly driving other cars the rest of the time since.

FYI, altho I ordered from Remy, the sticker on the battery I received says [Deka Intimidator EHP](https://remybattery.com/batteries/brand/deka-intimidator-batteries.html?srsltid=AfmBOorxsFi7eoMbizQPDMsF1q-32WuvMxLPyiLSgftX8ExWmqHWSfq4). IDK if there's any functional difference - it seems to have the exact same terminal connections as the OEM BMW battery it replaced.

Also FWIW, despite no indicator on the shipping box for 'this side up' and it clearly getting Ace-Ventura'd around by FedEx, it did not leak or show any signs of damage inside the shipping box. It was well padded with foam made to fit the battery and fill the entire shipping box. So far I'm happy and the car seems to be too.

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.

What is the sound of one hand clapping? Does a bear sh1t in the woods? If the bear does, is the turd a uniform size and power that will work with attributes of all the other different sized bears out there?

Chevy Bolt. Then it was recalled for the battery fire issue.
