Model overview based on user reviews  
The Bosch S3 car battery has received mixed reviews from users. While some appreciate its low price and convenient snap-off handle, many have noted significant drawbacks. The battery is often described as non-maintainable and has been reported to fail within a year or two. Users have experienced issues such as the battery not charging properly, and in one instance, it even exploded under the hood. Despite being a high-quality battery for its price, it requires careful maintenance, including regular charging and checking the date and voltage before installation. Overall, while it may be worth the money for some, others might prefer more reliable options like AGM batteries.

High-quality battery, worth the money. But next time I'll choose AGM.

Model S 3 45Ah Died in the second season. However, I don't have many complaints, as I didn't use it properly. In short: 1- when buying, check the date and voltage (at least 12.4V). Charge it before installation in the car (or -10 -15% capacity). Charge it as often as possible, at least once every 6 months, as the car does not fully recharge and this will gradually lead to a loss of capacity due to denser sulfation, and desulfation won't be achievable with any charging.
Low price. Around 3000 RUB.
Non-maintainable. However, recovery is possible and of course it will be done. But with plugs, it would be easier.
normal model, nothing special
