I recognised Yuasa as a long established and leading brand so thought it worth paying a higher price than the less well known brands.
The battery and separate acid bottle arrived very quickly and well packaged.
Unfortunately it is impossible to view the acid level through the battery walls.
The battery is supposed to be semi opaque so that the acid level can be viewed and filled to between the "Lower" and "Upper" level marks.
So the filling process was unnecessarily difficult and I will have to mess about removing the 6 caps and peering into the very small filling holes with a torch during on-going maintenance.
No overflow tube was included so I had to reuse the tube from the old battery.
On the bright side, it charged up fine and is now fitted and working but not what I had hoped for or expected from a brand leader.
