Battery Bosch or Deka

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.

Bosch, m-a tinut 8ani. Acum tot bosch de 70/75am luat.

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.

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 cargo bike advertises a range of 40-70 miles depending on level of boost. I get up to 40, at the very most, but never more. I use minimum boost only, and usually don’t ride up any major hills. I’ve wonder if this is just grade inflation for marketing or if my Bosch battery was just old/crappy when I got it.

looking at that reciept seeing Enhanced flooded its even worse, we are a main dealer of Bosch batteries and their EFB rated voltage is 12.6V when not in use not sure for the other big battery brands

I switched to Bosch after that. that failed after 2.5 years, just under warranty. so it can happen with any company. some batches might have good quality some do not.

My experience: Stay away from Bosch.
