Hi Everyone,
What experiences have been had with how long the lifespan of a Di2 external type battery might be? I've had mine for about 2 years and it seems like it might be needing to be replaced as it appears to be not holding charge for as long as it did previously. Normally I can do about 1500-2000km per charge, though that seems to have dropped to about 200 per charge. Has anyone had a similar experience?
Cheers,
Phil.
