Battery Varta or OEM BMW

I replaced mine with a higher capacity Varta 44ah 420cca battery, never had a flat since

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)

Varta blue 60ah de pe emag acum 3 ani jumate, fara startstop, 275 lei. Inca e bine in parametri, am o jucarie in bord care imi arata voltajul non stop.

I’ve had my iX for 2.5 years and have logged 122k miles. I haven’t noticed any degradation in battery capacity. Just the normal summer/winter fluctuations (live in Midwest).

Ia Duracell, am tot luat eu acelas tip de baterie pentru cheia de la masina, le schimbam la 2-3 luni, am pus un Varta, are 5 luni si este ca noua

Ich fahre im Moment nen BMW i3 von 2015 mit nur rund 15 kWh Batteriekapazität und knapp 80k km runter. Da die eh so klein ist und das Auto auch kein großartiges Lademanagement hat, knall ich (und wahrscheinlich alle Vorbesitzer auch) die Batterie eigentlich so gut wie immer auf 100%, was man ja eigentlich vermeiden soll. Das Auto liegt über den Daumen gepeilt ca. 10-15% (eher 10) unter den Angaben, die man so im Netz findet.

In my old Audi, I had a non-OEM battery and I did the +1 in the serial number trick. That battery failed in a couple of months. I honestly think it was a bad unit.
