• What is the best state of charge to keep the batteries on my etap groupset whilst the bike is in winter hibernation? I took it out for a brief spin and noticed the batteries had drained whilst being sat still on my rack.

  • best state is in the charger :)

  • Leave them disconnected on the shelf at around 50% charge at room temp. Dont store them with zero charge.

    Leaving batterys on charge in the chargers for long periods of time is probabaly the worst way to store them.
