Those getting replacements, how many batteries did you try out before you warrantied? my housing door was very tight, I couldn’t open it without using a ruler to get purchase on the little flap. Not sure how many replacements it will last….
Original lasted several weeks and so did the replacement, after that battery life got worse and worse (my guess would be down to water ingress). Eventually a battery would not last 24 hours!
My battery door was very tight and I needed to push the tab with the tip of a screwdriver to rotate it. The door was quite dog eared by the time the thing finally gave up the ghost.
There is some good thinking on other threads that extra covers might actually make the problem worse as it will be harder for tiny amounts of moisture or condensation to escape again. Similarly, we noticed that people with generally no problems keep their bikes indoors while the majority with moisture issues tend to keep the bikes in a shed or garage, again where it may be harder for small amounts of moisture/ condensation to escape again. Far from conclusive and I’m sure it doesn’t apply for everyone but an interesting thought I hadn’t considered before
I would have thought that condensation would have been more of an issue on the bikes that are taken indoors particularly during the winter.
