Old Battery Charger for RC Car in Wichita KS - Can it Charge Ni-H Batteries?

Click For Summary
SUMMARY

The discussion centers on the compatibility of an old battery charger, specifically designed for Ni-Cad batteries, with Ni-MH batteries. The charger in question outputs 5.8 volts at 500mA DC and is intended for 2 or 4 AA Ni-Cad cells. Chris definitively states that using this charger on Ni-MH batteries may damage the cells due to their requirement for a constant current supply, which the charger does not provide.

PREREQUISITES
  • Understanding of battery chemistry differences between Ni-Cad and Ni-MH batteries
  • Knowledge of battery charger specifications and functionality
  • Familiarity with charging current requirements for different battery types
  • Basic electrical concepts, including voltage and current ratings
NEXT STEPS
  • Research the charging requirements for Ni-MH batteries
  • Learn about battery charger types and their compatibility with various battery chemistries
  • Explore safe charging practices for RC car batteries
  • Investigate modern battery chargers that support both Ni-Cad and Ni-MH batteries
USEFUL FOR

This discussion is beneficial for hobbyists, RC car enthusiasts, and anyone involved in battery maintenance and charging practices, particularly those transitioning from Ni-Cad to Ni-MH technology.
