Cordless Drill Battery Question


Hello - new forum member here. Great info - I look forward to spending more time here.

My question is probably common but I couldn't find the specific question in search anywhere. I have a Ryobi drill/saw combo kit that I got about five years ago. As a non-professional but frequent DIYer it has been a great set. Earlier this year the batteries seem to no longer charge so I bought a new set (nicad). Recently, I have been noticing that I don't even get 5 minutes of use out of each battery.

When I first take them off the charger, I get a lot of power. But it doesn't last long. Put a few wood screws into a 2x4 and the drill is done. Could this be due to the age of tools? Perhaps the charger is bad? Anyway to determine which? I can't imagine both batteries are already dead after 6 months.

Honestly, for the $100 I paid for the kit, it doesn't owe me a dime, even if I figure in the $60 for new batteries. I have used these tools to renovate my old condo and my downstairs of new house. But before I buy a new drill (don't really need a cordless saw anymore since I now have a corded one) I want to see if there is an easy fix here

Thanks.

Cordless Drill Battery Question


were your origanal batteries NiMh or NiCad? is your charger a Rapid charger or overnight trickle charger. Most of the time you can charge NiCads in a charger designed for NiMh, but it's possible you are having compatability issue with the batteries and charger if you've changed the battery type

Cordless Drill Battery Question


You know, I'm honestly not sure which battery it is. I just looked at it but it doesn't say anywhere on the battery or the charger.

I know that when I charge them, I get the red light for a while and then eventually it goes to green. When I take the battery off, its a full charge but both of them die really quick.

If you want some help, post your Ryobi model number (as well as the saw's model number) and we'll search along with ya.

FWIW, I replaced my DeWalt originals with a couple of Lenmar equivalents. Works like new.
What benefit do the Lenmar batteries have over a new Dewalt battery?

Cordless Drill Battery Question


Here is what I have:

Battery charger model # G0452
Battery model # CS0928

The model number on the drill is wearing off, so I am attaching two photos.

Any thoughts would be helpful - is there any way to test the batteries vs. charger? Or could it just be that the drill is past its useful life and draining batteries quicker than it should?

Thanks.

I can tell you that I have had them for a year or more now, and have been very satisfied with their performance. Visually, there's no difference, other than the missing yellow "DeWalt" branding sticker.
If you find the source of these batteries, I'd be interested in trying them. I've sent some of my old ones to be re worked with new cells. Results have been good. I think it ran about $38.00 per battery.

Cordless Drill Battery Question


I think you are looking a serial numbers, not model #'s

Your drill is a P200, and I am assuming the battery is a P101 which should be right. I have heard a lot of complaints about the batteries not holding a charge, but really don't have any firsthand experience with these tools

I'll do a search for suppliers on the internet. That should come up with some choices.

Cordless Drill Battery Question


Thanks guys. I don't have the old batteries - I recycled them when I got the replacement ones. I guess I should look into new batteries. Maybe I'll try a rebuild if it would be cheaper.

Cordless Drill Battery Question


i recently brought a bunch of batteries to Interstate Battery to get new cells put in. I brought them 8 batteries and it cost a little over 400. I had 19v and 14.4's. None of these batteries hold a long charge long. They also have noticeably less power and speed.Not just one or two of them, but all of them. Maybe about a dozen screws and they lose their power. I should have bought new ones...they would have been about the same price. Anybody else have this problem?

Cordless Drill Battery Question


Disclaimer: I do not work for, nor am I associated with the following company.
I own nine (9) DeWalt 18 v batteries. Over the past five (5) years they have done like so many other OEM batteries, died. I found a company called "PrimeCell" that rebuilds power tool batteries for approximately 1/2 the cost of a new unit. They also upgrade the cells from (I hope I have this correct) 1200 mAh to 2400 mAh. This gives me more power and longer battery life. As I stated, I do now work for them but have had all nine (9) of my batteries rebuilt by them now and am happy with what I got. David

Cordless Drill Battery Question


The P200 Ryobi is a decent DIY drill and the 18V batteries are NiCad. I like my "blue" Ryobi powertools and have rejuvenated them with lithium batteries. Ryobi has a 2 year warranty and since you purchased them recently you should check it out. HD occasionally clearances out last years model of drill + Li batteries + Li charger that I puchase for the battery/charger (can't stand the lime-green tools)
