Revive Three Segways! Dying batteries

[sanfairyanne]

I have been asked to explore the possibility of reviving the batteries from three Segways which have been left for one year. They were stored with full batteries but have not had top ups.
I found some info' for a company in Australia that specializes in reviving Segway batteries but we are in Holland and unable to surface mail our lithium batteries.

We our getting this light sequence:

Segway one: solid red light, flashing green light
Segway two: single flashing green light
Segway three: single flashing green light

I wondered if anyone knows of a company in Europe that can revive (or attempt to revive Segway Lithium batteries.

Many thanks in advance.
