9 years on a Beverly 300, I recently measured it and it's at 50%. With one charge, it will definitely last me this year as well; when changing, I mean the same one

Purchased on November 9, 2021 and installed on a 2004 Tiger 955i. With the well-known "issue" of Triumph motorcycles and their electrical systems, this specific battery cranks strongly and consistently from day one until today. 7 months of use, without any charging needed. I will update in the future. So far, 5 stars from me!

For now, that is 3 months without use, the battery is working properly. In the f800gs, it doesn't seem to have any difficulty starting.

I will write again in one or two years, then its quality will be evident after all.

The battery is generally reliable, but during the winter when the engine is not in use, the battery needs to be charged every two months. Unless you take the motorcycle for short rides every 15 days. It lasted for more than 5 years

Average battery in cold weather the next day with difficulty starts the motor and the second day not at all. Tiger 1050 with Mama alarm. Not even time from purchase. I don't know what battery to get.
Update I recharged it again in the charger and now it works better and lasts longer than before. I can't understand why, it doesn't make sense.
