Battery Bosch or OEM Hyundai

The battery in my MB was the original Bosch so 20 years old when I replaced it.

(for general reference Lion are one of the worst battery brands out there. Exide are OK but that's far too expensive. Bosch and Varta are generally the exact same product with different stickers on and are always good, and rarely all that expensive.

Schedule the car to start, pre condition the battery if cold, climate to start, hop in and go.

I will second a class 3 Bosch. I have one in a hilly city that absolutely rocks the steeps and has a great battery life. Going on 2 years strong and I've had zero battery issues. It rains a lot here but no problems with the Shimano drivetrain either, just regular maintenance.

I have a Cube Stereo Hybrid pro (insert numbers here)

Priced about 3.5k retail, it's an absolute dream to ride. Quiet, huge battery (bosch power tube 800)

I can say from my experience if it drops below -20C a level one will only really keep the battery from losing power.

The Bosch has slightly lower Cold Cranking Amps at 330 vs the Yuasa at 360. Also Bosch has 4 yr warranty vs Yuasa 5yr.

Depends on the car, both highway speeds:

- Our good EV, Ioniq 6: went from 18kWh/100km to about 26kWh/100km.

- Our bad car, EQB: Went from about 26-28kWh/100km to about 29-30kWh.

I went to a Škoda dealer to look at a car to buy. The car was a Rapid 1.4 SE DSG which was advertised at £8995. The car was stored remotely from the dealer, basically in a field. The battery was completely flat.

A few hours later he came back with a new S4 018 Bosch battery (original one was Yuasa HSB056). He assured me it had the same specs, despite being a different brand (40Ah, 12V). He installed it, and then told me it was a “slightly different base size” from the old one.
