I have seen some test results on ID3 after 100000 km and still everything is quite good on the car. Battery is not damaged like on a cellphone if that is your worry.
Bosch batteries in my older bmw lasted around 5 years but I was told it’s recommended to change every 2 years.
Change mine in my 2016 Golf R to this battery and it's been great. EFB shite didn't even last the first 3yrs.
We have a 2009 Fiesta 1.4 petrol and replaced the battery with a Bosch battery 5 years ago after the same issue. The car does a few short journeys a week so not ideal but there's no signs that the battery is about to go flat.
Yuasa are high quality. I generally get Bosch S4 or S5 as they've never let me down.
My 2014 jetta TDI does the exact same thing as in your video when the battery is dying. I've had the car now for 6 years and it's happened 3 times. If the alternator checks out fine, then I would attempt a new battery.
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.
VW OEM batteries in modern cars often do that. I was lucky to detect slightly "lazy" cranking in my 2018 GSW 4Mo. Tested and showed %51 SOH even after fully charging it. Lasted 6 years almost to the date.
After 7 sets of battery drains, I installed a new set and left it on a shelf untouched for a week. Turned on and dead. Made a warranty claim with Bosch to which their lazy troubleshooting reply:
Let me start by apologizing on behalf of BOSCH for any inconvenience this has caused you. I performed a complete inspection: I 1st charged up your lithium battery. I then calibrated & tested unit with both alkaline & lithium batteries: PASSED. I know it’s an inconvience. But: Leaving any batteries in unit when not in use: ( Unit will drain all battery types )—( Unit self discharges batteries when not in use ) --That is why Bosch put in manual tom remove batteries. PG# 21—Attached – ( they actually don’t say how long the “ extended period is “) That way it is not considerd a factory defect. Other than that: unit is operating to all Manufacurers Specification & Tolerances. Best regards,
-Well I'm never buying another Bosch product again with customer service like that. Pissed that I bought this expensive paperweight. What product in today's world drains batteries when not in use? Clearly flawed engineering they are hiding and do not value the end users. A recall is in order.
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.
