Seen a number of posts about replacing cells inside a proprietary battery case. Anyone have experience obtaining a custom replacement from Cannondale that fits the frame of the bike? Looking ahead. Concept of recelling makes me a little nervous.
 
Replacing the cells is usually a last-ditch effort for when the manufacturer stops making the pack and won't support you by rebuilding it. Or, when the proprietary pack is priced ridiculously high. (Juiced did this)

Careful though, a rebuilt pack is not always done to the highest standards; you have to trust the rebuilder. In NYC, rebuilt packs are specifically outlawed for this reason.

Good information. Thank you. I'm thinking way ahead. Existing battery will probably outlive me.
 
If you haven't yet, read about battery care. Specifically:
  • Try to keep it between 20-80% state of charge. This will double or triple your battery life.
  • It's fine to fully charge it when you need the full charge, but don't leave it more than a day or two fully charged; this kills their lifespan quickly.
  • If you're not going to ride for a couple weeks or more, ride the bike to get the battery down around 50% state of charge, and bring the battery indoors, if possible. Try to cycle the battery at least every few months.

Have read quite a bit, watched videos. This, however, condenses everything down to the basics which is good. Thanks!

What model and year Cannondale do you have? If it's fairly recent, it should have either a Bosch PowerPack (on frame) or Bosch PowerTube (in frame) battery. Both are readily available, and are not Cannondale proprietary. Only the mounting systems are.
