Battery OEM Toyota or Deka

As someone who bought their first Prius V (Lithium Ion- Australian Model) in 2013 No issues with any degradation in battery from 12 years ago.

After 16 years and 140k miles, our Prius battery is still going strong.

I bought mine last year 2016 SR5 4WD at 116k miles. I'm at 140k today and it feels like new. I only had to swap the battery because I forgot to check how recent it was when I bought it.

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.

My neighbor bought a Prius 15 years ago,whoever they came out, the dealer told him it would cost $5000 for a new battery replacement. It lasted until 2024, it cost $1500 to have new battery put in,aftermarket of course

Deka. Solid battery.

Had the same problem today... Battery died (ok, a few cold days in Belgium , nights up to -5°C) and assistance for jumpstarting it was necessary, luckily I had autoclub membership. Car is only 30 months old. We drive it multiple times a week for shopping and trips to the seaside. Checked the car in to the Toyota garage and test of the battery was negative, battery was dead. I was very pleased they replaced the battery with a new one under warranty!

I just upgraded mine a few weeks ago, ended up getting a DEKA AGM 9AGM47 More CCA and far more reserve capacity than the stock battery (120 mins) I was at ~35k miles and my OEM battery was failing fast.. I couldn't leave it in the accessory position without the engine running for more than a minute or two or it would barely be able to crank. The OEM battery is crap as far as I'm concerned
