This review is from: Ryobi - Ridgid Replacment Part # 130446001 BATTERY PACK 12V-DC LI-ION (Misc.)
I own one of the 12V LiOn Ridgid drills + charger and have burned through both batteries. Thinking I needed new batteries I read reviews of the charging unit and people indicate that it is the charger that is bad and not the batteries.
If your charger says the batteries are defective and won't charge buying new batteries might not help.
