What I Look for in a 9V Intelligent Battery Charger
When I review a 9V intelligent battery charger, I first look at how well it charges without overcharging. I want a charger that can detect battery type, stop automatically when full, and protect the battery from heat or damage. I also pay attention to whether it works with both rechargeable NiMH and NiCd 9V batteries, since that gives me more flexibility.
Charging Speed and Efficiency
