Yepp, you can replace it..BUT...its more expensiv to buy a new battery then it is to buy a new hand drill...almost.
If you want to replace it i sugest you go to the store where you bought your hand drill and buy one there.

Good luck to you

Sometimes, the charger will overheat and fail. Try unplugging the charger overnight, plug it back in the next morning, then place the battery in the charger after waiting a few moments. Normally, this will correct the charging discrepancy.

My battery does not hold the charge, i will charge it for 24/hour and it only last 5 minute, why is that, iI buy this product for wife when went to Iraq, and when i talked ton her on the phone three months...


NiCad batteries have this problem when they are recharged frequently after being only partially discharged. This is also the case when the batteries are left in the charger continuously - even if the charger is described as being "automatic". I have old 12v batteries that I have been using for 20 years, but I only charge them for a few hours, and only when they have run down enough to be useless. I prevent leaving them too long in the charger by using a timer that cuts the power to the charger after a couple of hours. A couple of years ago I bought new drills and chargers, and believed that the chargers would be automatic and so could be left plugged in. Those batteries only lasted a couple of years, while the old ones are still going strong. I now use the timer for any of these chargers, automatic or not - but I had to buy new batteries first. good luck, Al K

I have a B&D Cordless Grass Hog. It suddenly won't charge. When I plug in the charger, the light won't come on. Is it just getting too old or is there anything I can do to fix this one?


Black and Decker has had numerous complaints from consumers. Most of them are over a failed batttery or batttery charger. There have been reports that their service centers refuse to repair them, stating that it is not cost effective. so, if a unit is still under their warranty, they probably just replace it. In your case, if it is an older unit; consider yourself one of the lucky ones that had one to work for an extended period of time. If you choose, the charger and the batteries for it can have their electrical capacities checked with a simple volt-meter tool. The tool doesn't lie and would let you know if the charger's output is correct and if the batteries are holding their charge.

It does not turn on even if it was charged for 24 hrs


When it charges, does the red light come on on the charger? Some of the CST2000 chargers make bad connections, and they don't actually charge.

Make sure the red light is coming on when you're charging the battery. If the light is coming on and you still can't use the trimmer after charging, you'll need either a new battery or a whole new battery pack (the black handle of the trimmer).

Hope that helps!

How long should trimmer run on a charge.


How large is your yard? On a small yard (like a townhouse front & back yard) the trimmer should last long enough to do the yard a couple of times before needing to be recharged, but it depends on the individual yard, how many weeds you have, and whether you keep it running a long time.

If the trimmer charges at all but not for a very long time, it's either the charger or the battery. Check the charger when it's charging to make sure the red light stays on -- if it goes off or blinks, you need a new charger. If the charger light stays on but the battery doesn't hold a charge, you need a new battery.

Hope that helps!

CST2000 can't get the battery off when pushing the two release buttons.


Black & Decker didn't make it easy to remove the battery pack. You have to push both buttons in at the same time, while pushing the battery pack forward. It takes a little while to get good at it -- you have to hold onto the trimmer with the same hand that's pushing the buttons in, while pushing the head forward with the other hand.

If you're only taking the head off to charge the battery, you can charge it while it's still attached. The hole for the adapter is on the back of the head, so you can plug it in while it's attached to the trimmer.

Hope that helps!
