Battery won't charge
One battery out of 4 won't charge on any charger. It's junk.

    Excellent, but...
    My last Ryobi batteries died 7 months after the 3 year warranty expired, which sucks, but coincidentally there was a very good sale going on the same day and I am in the middle of a big renovation. Once your batteries start to pass 3 years, monitor Home Depot for sales, which happens often. I love these new ones because they tell you how much battery you have left vs my old ones which always left me hanging unless I always charged them before jobs. I'm upgrading from 1.5 Ah to 4.0s and I got 2 of them! This is a huge upgrade but it'll be heavier. Remember to recycle your old batteries at HD vs just throwing them in the trash!

    Ryobi batteries
    Excellent batteries, price reasonable, no complaint. One battery last me all day running multiple tools. All my tools Ryobi seeing that they are very reliable. However I bought my pair of batteries when they had the deal going which was buy the batteries you get a free tool but I never received my free tool. Not switching though, just bought a circular saw, go ryobi. How do I get my free tool which I think I deserve.?

      While rebuilding our deck, we decided we needed additional batteries so we could stop swapping from drill to saw to impact wrench. This two pack was on sale at a great price. Finished our deck before the first snow day.

      I bought 3 packs last year and I have bought 4 more packs this year. Really great batteries and last a long time with the weedeater, blower, edger, hedge clipper, fans, tire pump, drills, vacuum, radios, saws, and nail gun. Those are just the tools I have. Love that they have the lights to tell you how much charge is left so you know if you need to have another battery with you. I will probably buy 1 or more packs before the season ends at the $79.00 price because it is a great price.
