Description Got a used internal Focus 378mwh battery from my Jam2 for Shimano E8000.
It’s had about 950 miles use over 2 years and has now got some dead cells. So only charges to 4 bars won’t charge beyond. As can see from pictures, freemax software shows 77% battery charge, and that is the max it goes to.
Just had a new battery installed by local focus dealer. And so this now spare.
As seems to be the normfor these batteries the case has some cracks, but dealer told me most he sees are the same. A design flaw perhaps. But as above battery was working fine except for the reduced charge capacity and therefore range.
May be of use to someome looking for a cheaper option to replace a completely dead battery, or who can’t wait for stock (I was 4 months waiting for the new battery).
