Since purchasing my new 51Ah pack over four years (as per today 4 years, 7 months and 6 days) ago, I’ve been tracking the degradation of the pack’s capacity over time with periodic long-distance full-cycle trips.
With one of the first nice and not freezing days in 2021, I thought it would be nice to see how the battery was doing.
My pack was purchased in March 2016 and installed August 8, 2016. If you’re interested to know more about how this pack was chosen, got its final size and capacity, please head over here to read all about how to choose a TWIKE battery, should yours be depleted and in need of a replacement.
This is how the current pack started its life in TW560:
74723 km (and one low-mileage 2020) later, I’m here:
So, now, without further ado – the number we’ve been waiting for…how many Wh does the pack still hold?
For those interested in some more data – I’ve started to keep a tally of all my capacity tests and will eventually start an own page tracking this pack’s capacity decline.
