Ensuring a Proper Battery and Charger Match

Written by Anton Beck - Battery Product Manager
Posted on May 1, 2015 at 10:48 AM

In today's battery and charger market companies may provide either battery pack assemblies or battery chargers, but few provide both. In the past buying a battery from one source and a charger from another worked just fine when using the older NiCd batteries with overnight chargers. However, with today’s new battery chemistries and the increasing need for faster charge times, careful matching of the charger to the battery is essential. Without proper battery and charger matching, safety, cycle life, or run-time may be greatly affected.
