Will this work on Ridgid 24v tools?

Asked by: Medfly
It is true that the Ryobi 24v battery will not fit the Ridgid 24v tools even though at first glance they look compatible. Let me be clear; tinkering with a lithium-ion battery is EXTREMELY DANGEROUS and should be avoided !! These batteries are not the same as NiCad or NiMH - they are much more volatile. A better solution than attempting modifications would be to use a RIDGID 18 volt L-ion in the 24v tool or pony up the $100 or so to get a Ridgid 24v battery. Most of the Ridgid 24v tools state on the label 18v/24v. Your life and your health are worth much more than the money spent to buy the correct battery.

how long to charge battery,

I have left in all night and its only half charged??? so it looks like battery defective, and or charger defective.
Asked by: FRANKLIN
The 24 volt battery is very quick charge -- the average is 2 - 3 hours. You are correct if the battery takes this long to charge it is now a bad battery --- the reason I have to have several batteries on hand. They don't last more than a few years.

Lithium 24-Volt Cordless Battery for 24-Volt Cordless Tools is rated 3.2 out of 5 by 50.
Rated 1 out of 5 by from Not a good value. Costs more than a comparable DeWalt, but only lasts 1 or 2 seasons. I'm sorry... Not a good value. Costs more than a comparable DeWalt, but only lasts 1 or 2 seasons. I'm sorry I bought 24 volt tools. I certainly won't "upgrade." I guess I wasted my money on 24 volt, but who knows where HD is headed with their gardening and battery operated tools.

Rated 2 out of 5 by from Ryobi 24v Battery After 2 years the original battery died ! I went looking in several Home Depots for another one , they don't sell them in any stores. You have to order them online! I paid 129.99 for 1 battery pack only because I really like the weed wacker .. What really bothers me is how expensive the batteries are to replace I could have bought another weed wacker for less money but decided against that because mine was only 2 years old!!

Rated 5 out of 5 by from You MUST keep this charged over the winter! OK. Here's the deal, people. I'm not saying it's fair or that you necessarily should have known or anything like that. But this is the way that it is: if you have this 24V battery and associated tool(s) and charger, you MUST occasionally re-charge the battery over the winter or whenever it is sitting idle. The protection circuitry constantly draws a small charge from the battery, and will, over a couple months, drain it down to nothing. You can not let it sit at nothing for a long time. If you do, you WILL KILL IT. So, over the winter, every so often, I push the button to check the charge. When it gets down to one or two bars, I give it a recharge. I've had my 24V string trimmer for two years now, and the battery is just as powerful and long lasting as when I first got it. And it's because I have made sure to keep it from sitting totally discharged. Li-ion chemistry has issues when the voltage between anode and cathode gets too high (it explodes!) and when it gets too low (it reacts and ruins the battery and can vent when recharged after this). This is why all Li-ion batteries sold to consumers have protection circuitry to guard against over-voltage and short-circuit. Unfortunately, it can't guard against under-voltage besides preventing power-draw from the terminals. So if it gets drained down, then sits, the protection circuitry will continue to draw power. And will ruin the battery. So keep these things charged during off-times if you want them to last!

Rated 5 out of 5 by from Folks Battery has a 3 yr warranty! Simple keep your receipt. Call 1-800-HomeDepot, they will refer you to a local tool repair shop. Take battery & charger in & viola! Walk out with new battery or charger. On top of that the edger trimmer combo comes with a 2 yr warraty & for $10 I opted to purchase a 2 yr Home Depot replacement plan. Yes keep battery in charger during winter if you have 2 batteries alternate then monthly. Mine is workin like a charm. I was told that RYOBI was discontinuing their 24volt tools. So I opted to call Home Depot which in turn they transfered the call to RYOBI customer service. Folks keep your receipts & since they dont use ink on their receipts make a copy & fold in the receipt.

Rated 5 out of 5 by from Great Discontinued Battery This rechargeable battery charged up quickly - 1 hour. It runs my hedge clippers and string trimmer from Ryobi just fine. However, you cannot leave this battery out of the charger for any length of time as the battery will discharge and not recharge again. Charger reports battery defective. This was an expensive lesson to learn. You also must order this battery online as it's not available in the stores. I believe Ryobi has discontinued these batteries and devices. But for using this battery and devices for its first season, they work great. Thanks.

Rated 3 out of 5 by from product not found in stores This product is not found in stores making it very inconvenient when a new battery is needed. The product is very over priced and there is no substitute. Unfortunately the weed eater requires this product and we are forced to pay the high price. The weed eater and the battery are excellent just wish the price was reasonable and available in stores.
