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.
Varta B33 Location: Right Trunk under Taillight
Thx everyone, in the end I found a Varta B23 on discount, which is slightly bigger and slightly stronger (45AH) and fits.
I’d go for Vatra. Massively popular in Finland where it often gets lower than -30 in winters. I had mine on an F10 and the car was stationary for 2 weeks with average temp of around -15 degrees. Zero problem
Acum recent am schimbat bateria la mașină, am dat în jur de 530 de lei, baterie de la Varta. Eu am optat pentru varianta la 530 că am renunțat la funcția start-stop, altfel costa aprox. 800 de lei. Cel puțin din experiența personală, este o marcă super oke dpdv al raportului calitate-pret. Înainte de schimb tot Varta am avut, bateria originală de când a ieșit din fabrică (2013)
Deka. Solid battery.
Try Varta, I replaced crappy ac delco twice in a year, replacement battery died in less than 2 months
Replaced it with varta, going 3 months strong now
I have the same problem! Overcharging - 14,9V. Had AGM Varta, I put new Acid Varta and recoded to Lead Acid battery. But there is no difference - charges 14,9V, I think, this is too much!
