If you have followed my blog over the last couple of weeks you will have read that I have been having a problem with my Shimano Di2 on my Specialized Creo road bike. I don't use this bike very often so does not get that many miles on it. I do give the battery a top up charge every 6 months or so. About a month ago I went to use the bike and the battery was flat so I gave it a full charge. The next ride it was working perfectly but the next time I went to take it out for another ride the Di2 was not working again. I thought it could not be the battery as I just charged it a couple of weeks ago. I checked all the connections to the mech, shifters, charging port and junction block, all seemed ok. I knew the software / firmware will have probably been out of date as it has not been updated since new. I tried charging the battery again but would not hold its charge. I dropped the bike into Evans Cycles at Durham and Dan plugged it into the laptop. He ran the diagnosis and no faults come back. He then updated all the software / firmware but the battery was not even recognised. He did not have a spare one to swap it over to double check it was defo the battery. I did a quick google and there was stock in the uk and best price was just over £140. I checked Infinity Cycles stock and they had one in. With them being bought out by Specialized uk they run Specialized's price match policy so I collected the battery the next day and paid £140, cheers Peter.
The battery is hidden down the top tube on the Creo so gaining access is via the TCU hole, it is very tight and you have to take your time. I swapped over all the zip ties around the battery and put it on charge. After a good few hours the charging light went out on the charger box. I tried the gears and they worked. I tried again the next morning and they were still working. I checked the battery charge status light and it was solid green so the new battery has solved the problem. I then slide the battery back down the top tube, tucked all the other cables down and refixed the TCU display unit. Hopefully this one will last longer than the first battery, especially at Shimano's eye watering rrp!
RRP £159.99 and I paid £140 from Infinity Cycles. Discount 12.5%

I just love using my Silca allen and torq key set, the quality is unreal, well worth every penny I paid for them. I noticed the rrp has gone up yet again on this set.
