Bought this battery on 15/11/2024, and paid 30 euros more than a no name would cost me, just to have a BOSCH battery thinking it would last, and it had a 2 year warranty.
Battery died on 15/03/2026. (1 year and 4 months)
It says that the battery has 2 years warranty, but it's only 1 year unless you install the battery in a bosch ONLY service center (not a certified reseller or a certified electrician)
Got my car tested at 2 places just to be sure my car doesn't have a parasitic draw, both electricians said my car is ok and that my battery is dead.
I drive an opel astra h 2007 1600cc.
I won't be buying Bosch again, due to fake advertising of 2 years warranty, and short lifespan, with a car that is daily driven.

In the Astra H, it lasted 5 years with daily use; I believe it performed well for Bosch. At the first signs, I charged it, but instead of improving, it got worse until it left me stranded

Installation 04/2017
Replacement 06/2024
7 years and not bad... I wouldn't have changed it, but I got stuck and had to push the car with the starter, so it got a bit damaged, so I changed it for psychological reasons.

Purchase 11/2017, Opel Astra G 2001, 1.4-16v.
Vehicle use approximately 2-3 times per week, mixed cycle, 7-8K kilometers per year.
Absolutely satisfied!!!! The last 2 winters, charged only once for maintenance.
Well, time for the next one... 3/2024... It lasted very well, I will buy the same again!!!!

Purchase on 15/6/2017 replaced with the same one on 24/3/2023, approximately 6 years, on Ford Mondeo mk3 1.8. It didn't let me down, just after 6 days of inactivity, it seemed to struggle a bit to get going, and because I had a trip, I changed it.

In my Opel Astra H, it lasted 2.5 years. It left me completely suddenly. One day it was working fine and the next it completely broke down to the point where I had to worry about my car. The voltage at idle is 14.3 volts and there is no current leakage in the car. I took it out of the car and charged it, but as soon as I remove it from the charger, its voltage drops dramatically. From such a company, you expect more...

37 months is the duration for me. I bought it in November 2018 for 70 Euros.
Before I put the BOSCH, I had VARTA which lasted 4.5 years and had higher AH.
That's why I chose VARTA.

2 years and 10 months lifespan in a two-liter car. 4 stars for its reliability until the day it operated. I expected it to last through a third winter. Maybe the car needed more AH, although the manual suggested a 60. I replaced it with an 80 from an unknown brand.

Installation on the 10th of 2017 on a Hyundai i30 with no issues.

The lifespan is 2 years and three months. It was used in a modern and properly maintained car. Unacceptable product for the name of Bosch

If there was a downside, I would mention that the battery lasted only two years, with problems in the last three months. Anonymous ones have lasted up to seven years. STAY AWAYYYYY

It is the third time I bought it. The previous 2 lasted me 6 years each. Two years ago, I bought it again, left the car due to COVID-19 for 6 days with the alarm on, went to get it and it was almost dead. I didn't even try to jump-start it because I would have made it worse. I connected it with cables, took a 20-kilometer drive at 80-100 km/h, and it has been working perfectly for a month now. I have it in an Astra G (2003) 1.4L. If any issues arise, I will come back.

UPDATE
In the end, the problem of the battery losing power was due to a faulty alternator. I replaced it and even today, five years later (June 2022), I have the same battery without any issues. The old alternator was an 80-amp one and in poor condition, while the new one is a 120-amp one and charges it very quickly.

Update
Finally, the battery gave up in May 2023. It was purchased in October 2017

Very good battery so far. Because most people talk about the lifespan of Bosch, I will come back when a sufficient amount of time has passed, but for now, I am satisfied for a month.

In a few days (19/4/24) I will complete 5 years of use with Opel Astra H 1.4 ('2007), with occasional use of the car (only 15,000 KM in these 5 years of use) and now it has started to show symptoms of power loss, indicating that it needs to be replaced. For the money I bought it in 2019 (62€), in these 5 years of use it has more than paid for itself.
