Safety Information


CAUTION: Use of charge algorithms with batteries that were not designed for them, is done at your own risk, Delta-Q is continuously testing and updating charge algorithms for various batteries. Though many algorithms will work with a range of batteries, variations in manufacturing, chemical composition, health, and other properties may cause unacceptable charging performance.

This document is only for the use of Authorized OEMs and Distributors. Use by any other parties may void the battery and/or charger warranty.


Always closely monitor a suggested battery/algorithm combination for at least three cycles to ensure the batteries are being properly charged. If you are not sure of how to monitor a battery charge, contact Delta-Q Technical Support for advice.
