Battery Tesla or Bosch

For context, I have a first generation Tesla Model S - 2014. It has 215,000-ish miles on it. The battery capacity has gone down by about 10-12%. It still runs and drives like a dream. It's on the original battery.

I've never had any reason to regret my decision in the past 15 months of ownership, and I absolutely love driving it.

Bosch batteries in my older bmw lasted around 5 years but I was told it’s recommended to change every 2 years.

As an owner of a 2016 model S (bought new) with 228k miles on it, still on original battery with a range reduction of less than 15% compared to new.

Just replaced mine in my model 3, it lasted about 4.5 years before I get the alert on my app. Had it replaced in less than 20 minutes via mobile service in the app (there was already a tech in the area).

Change mine in my 2016 Golf R to this battery and it's been great. EFB shite didn't even last the first 3yrs.

I don't want someone else's crusty ass battery. Charge times are already low and are plentiful (Tesla at least), I don't see the utility of swapping the battery out when I could stop for like 15 mins.

looking at that reciept seeing Enhanced flooded its even worse, we are a main dealer of Bosch batteries and their EFB rated voltage is 12.6V when not in use not sure for the other big battery brands

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.
