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 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 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 2 out of 5 by from Battery Dead? Try this fix Like everyone else, my battery went dead. Left it off the charger in the winter for a month. Plugged it in and charger indicated battery was defective. So, I took the battery apart - there was no way I was going to spend $119 for a battery. Using a voltmeter, I noticed that the T2 terminal and positive terminal registered small voltage when tested. However, when testing the negative and positive terminals there was no voltage. When I tested the negative wire before it entered the circuit board and positive terminal it registered voltage. My solution was to splice in a wire from the wire going into the center of the circuit board to the wire coming out of the circuit board (circumventing the circuit board). Put the battery back together, plugged it in the charger and it indicated testing for a few minute; then it turned green and started charging. Battery works fine now. I uploaded an simple diagram of my fix. The blue line is the wire I spliced in. As a previous poster indicated, you must keep this battery on the charger. I think what happens as the previous poster indicated, is that the internal circuit board draws a little bit of power constantly. When the power in the battery gets too low (dead), the charger registered it as "defective." Is it a design flaw with the circuit board? Probably. From my understanding, lithium ion batteries have no memory and can be charged many thousands of times without a problem. Hope this helps someone!

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.
