Battery Panasonic or OEM BMW

My 2019 Mazda 3 died on me randomly a couple months ago. The dealership ran a test on it and it came out fine. I changed it anyway as it was a stock 5 year old battery. It’s been fine since, even in the -20°C temps where I am.

I just replaced the battery on my eco drive from maybe 2008ish? Battery itself was 14 bucks on ebay, oem brand(Panasonic). Swap took 5 minutes.

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).

I had one with the battery that lasted just under 12 years.... Old original BMW batteries are built different! Especially if the car is driven regularly.

Same with my 2008 BMW 535d. 900ah and still going strong

I had a battery in a 93 BMW last forever like that

My original Panasonic lasted seven years in my car when new

After the original battery, i replaced it with a Panasonic battery (nasa ₱5k that time) in 4th quarter of 2019. Etong panasonic battery life, last June 2024 ko lang napalitan (after 4 to 4.5yrs of service )????

Out of stock yung Panasonic so pinagtyagaan ko nalang yung Motolite priced at ₱7k recently (shucks i hope this battery lasts kahit 2yrs).

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.

I’m not satisfied with the range (70 miles) or the charging speed (max 19.2 kW via J-1772, taking 4 to 13 hours to charge) of the BMW batteries in my Lion Type C electric school bus.
