6 years on the Sh300 that I use daily and store in a garage. 1-2 times a year I put the battery in a charging-maintenance device as a precaution! I won't say anything else.. Flawless!

I had the BMW GS Adventure 2017 and it lasted until July 2022 with regular maintenance because due to my naval profession, the motorcycle was sitting for months.

My Honda Integra 750 lasted 14 months and 12,000km. It is the battery recommended by Honda. The motorcycle does not have an alarm, GPS tracker, etc., its electrical system was checked after replacement, everything is ok. Huge disappointment and very expensive

Worn out from the factory on a new motorcycle,
without alarms and extras on top,
with nails and with teeth,
with charges and maintenance,
it lasted up to 22 months.
With 17,500km in 22 months, the battery died. Very bad product for its price. The old good Yuasa batteries lasted 6-7 years.

The best battery with the most amperage. I use it on my ktm 1290 sa. The previous one lasted 2.5 years without chargers and maintainers.

Update 22/01/2021. I take back what I said. The Manisia did indeed last 2.5 years. However, the new one I bought, in just 4 months (installed on 24/09/2020), it said its poem. As the previous commenter said, it burned out. Luckily, the store where I bought it covers me with a different battery.

I bought it and after 5 months, while I had checked the power of my machine, it broke down, resulting in the store where I bought it telling me that it only has a 3-month warranty and they won't replace it. There is no reason then for such an expensive battery.
