I have not been able to remove those ryobi battery packs that are in my weedeater, drill, lights, etc. I finally found an easy way to do this! Just WD-40 the end that sticks into the tool, and presto, you can easily take it out to recharge it again! I know guys, this may seem ridiculous, but us gals with small hands can't eject these things! Anyway - problem solved!
