I bought this battery because I read reports that it's chemical make up made this battery have a longer shelf life and charge/discharge cycle. The fact that these battery's are fully sealed and maintenance free was also a bonus.
It's small footprint made it fit just right in the c5's foot well so I could use the standard c5 battery strap, this meant that the battery did not slide forward whilst under heavy breaking.
At first I was very impressed with this battery, delivering strong constant power, enabling me to get around 13 hilly & 20 flat miles per charge. Whilst my usage was fairly heavy (every day use) I never over discharged the battery, never left it in a discharged state, and always charged it after a run, even if it had lost only one green segment.
5 months on this battery is almost dead! It will charge but it now hardly gets me out of the village before I'm beeped at and on the last red segment. Is this battery crap ? Do I have a duff one ? One thing is for sure I have a 4 year Warrenty with it, so I will be taking it back and will try again with another.
