what charger is needed for these batterys......can i use the ni cad charger?

Asked by: hallze
NO, NO and NO. The older NiCad chargers will destroy your LiON batteries. Thankfully they won't even try to charge the batteries. Get the new 6 battery charger system. It is way smarter and will help your batteries live a long time.

Customer Reviews

18-Volt ONE+ Compact Lithium-Ion Battery (4-Pack) is rated 4.5 out of 5 by 101.
Rated 1 out of 5 by from Poor Battery Life I have bought two packs in 2 years. Total of 8 batteries 7 are dead will not charge. Batteries stored inside and limited DIY usage. Use to rave about Ryobi and the One+ system. Went with One+ for compatibility across tools. Now regretting my decision/investment in my tools.

Rated 5 out of 5 by from Superior to their NiCad 18 volt versiion These ion batteries for Ryobi tools are far superior to their terrible Ni Cad version. Ryobi should offer an exchange program with an incentive special price and take back all their ni cad batteries so they can properly recycle or destroy them. Not sure how long a life span these will last but I have used them and they work terrific. I can trust the use of my tools without their dying on me in the middle of a job.

Rated 1 out of 5 by from Not a review... a complaint... Without amp hour rating, it is impossible to assess this product. If Home Depot wants to mislead customers, fine. That's what happens when you omit critical information. Comparing Li Ion batteries to nicads is insufficient. Lame.

Rated 1 out of 5 by from Battery won`t charge I bought 2 of these batteries about 5 months ago. When winter was over and I went to use them they were both dead. I also bought another base to charge them and it won`t work. Instead of complaining to the company I just ordered the 4 pack. Well only 3 of them work. I don`t know what to do. I`m so disappointed in Ryobi. I might just have to take them back. Now I have 3 that work and 3 that don`t. I hope you have better luck than me.

Rated 1 out of 5 by from Don't waste your time with these batteries Ryobi offers these compact Lithium-ion batteries but they also offer the high capacity lithium+ batteries. I have had 3 of these batteries die and won't charge. If you have a tool (such as the Ryobi bluetooth radio) that drains the battery completely, it destroys the battery. Also these batteries last about 20 - 25 minutes in my jigsaw before having to be recharges. That's why I bought the 4 pack but then when 3 of them die, it you are working for 20 minutes and charging for a couple of hours so not a good fit for me. I did upgrade to the high capacity and have had much better performance. So my advice is to not buy this junk go for the better ones you will be happier.
