Ryobi battery getting old/weak?

Have a ryobi drill with one batery , 18v (see picture here):

Its maybe 3-4 years old. How long do they last? Mine now, after charging, is only good for about 5 minutes of drilling small drill bit holes. Is it time to buy new as shown in the ad on ebay? Or, buy a whole new drill/battery?

Yeah, sounds like you are ready for a new battery. 3 or 4 years of use is not bad for any NiCad battery.

Unless you have some reason why you want a new drill, or you want to change to one that has battery compatibility with other cordless tools you own, then "if it ain't broke, don't fix it." Just keep buying new batteries every few years until you find some reason to upgrade your drill.

If you buy a battery from eBay make sure you test it as soon as you get it.

In my profession, we deal with uninterruptable power supplies (UPS) that have very large, expensive arrays of batteries. Buying a used UPS is a pretty normal thing but you have to be a LOT more careful about buying used batteries. People will rip you off.

I'm sure the same is true with consumer rechargeable batteries. Buyer beware.

Just go to Home Depot and buy the two pack.

If the batterys bad the charger should of had a blinking light.

You are at the end of it's life---$59 for two batteries at the Depot----or look for a special for about $100 that includes a tool you want.

I just picked up an impact gun and a drill--charger and two batteries for less than $100---

Really?? Man, I didnt know! When I put in in to the charger, I dont get a blinking light! So, does that mean the battery's still "good"? What color is that blinking light? (just thought- I have the owners manual saved. Should maybe puull it out and study it....)

I have two differant style Ryobi chargers, both have red and green lights.

Red for charging, green for fully charged. When the battery goes bad it blinks from red to green.
A few things that can give you a faulse reading is trying to chage a hot battery. If you using it and it goes dead your suppost to let it sit a few mon. to cool off before charging. If the charger is sitting in the sun while it's charging it will since heat and not charge the battery.
The contacts get dirty on the charger and the battery, I just use a pencil eraser to clean them off.
But batterys that old most likely are shot.

I get it now, Joe..

I have the same batteries.....I get 4-6 years of use......depending on what I'm doing.

Leaving the battery on the charger for extended periods is not good for it....

If you plan on useing more Ryobi tools....go buy the tool of your liking with the Li battery.....those batteries work in your exting drill
