    My unit is now 2 years old, and the battery seems to go down MUCH FASTER than it did when new.

    I am having the same problem, the unit was fine after the first charge. Then after each use the time of use has become shorter and shorter. I thought they fixed the memory problem with these batteries.

    after the first charge, the length of the charge has been getting shorter and shorter. I thought they fixed the memory problem with these batteries?

Battery companies don't want anyone to know this but if you run the terminals over a magnet, the memory will harmlessly be erased. However, a battery may overcharge so keep an eye on it will recharging the next time.

The so called memory effect only effects NiCads,
The older B&D trimmers use a Gel Cell battery (they have a recycle symbol with Pb on them, Pb is the chemical sign for lead)
If you run a Gel Cell down all the way, you will quickly DESTROY it.
Gel Cells should only be run down until you notice it slowing down, and then recharged ASAP. These units should be kept on charge whenever they aren't being used, or recharged at least once a month, whether they are used or not. If they aren't on charge all the time, they should be charged before using.

If this doesn't fix it, you've already ruined the battery, go get a new one.

Most batteries have a memory. So, if you don't let it completly die bofore you recharge it, the life of the battery will shorten to the charge you give it

18v 12 cordless trimmer/edger. Why won't it start?


the trimmers switch may be faulty.

CHARGING THE BATTERY PACK
Battery packs for this tool are shipped in a low charge condition
to prevent possible problems. Therefore, you should
charge them until the green LED on the front of the charger
comes on.
NOTE: Batteries will not reach full charge the first time they
are charged. Allow several cycles (operation followed by
recharging) for them to become fully charged.
CHARGING A COOL BATTERY PACK
See Figure 3.
If battery pack is within normal temperature range, the red
LED on charger will come on.
NOTE: If the charger does not charge the battery pack
under normal circumstances, return both the battery pack and
charger to your nearest Ryobi Authorized Service Center for
electrical check.
n Charge the battery pack only with the charger provided.
n Make sure the power supply is normal household
voltage, 120 volts, 60 Hz, AC only.
n Connect the charger to the power supply.
n Place the battery pack in the charger aligning raised rib
on the battery pack with the groove in the charger.
n Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger.
n Normally the red LED on charger will come on. This
indicates the charger is in fast charging mode.
n Red LED should remain on for approximately 1 hour
then the green LED will come on. Green LED on
indicates battery pack is fully charged and charger is
in maintenance charge mode.
NOTE: The green LED will remain on until the
battery pack is removed from the charger or charger is
disconnected from the power supply.
n If both yellow and green LEDs come on, this indicates
a deeply discharged or defective battery pack.
Allow the battery pack to remain in the charger for 15
to 30 minutes. When the battery pack reaches normal
voltage range, the red LED should come on. If the
red LED does not come on after 30 minutes, this may
indicate a defective battery pack and should be
replaced.
n After normal usage, a minimum of 1 hour of charging time
is required to fully recharge battery pack.
n The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
n Do not place the charger and battery pack in an area of
extreme heat or cold. They will work best at normal room
temperature.
NOTE: The charger and battery pack should be placed
in a location where the temperature is more than 50°F
but less than 100°F.
n When batteries become fully charged, unplug the
charger from power supply and remove the battery
pack.

BLACK AND DECKER CORDLESS POWER PACK FOR 12 VDC SLA BATTERY #243215 for a Grass Hog Cordless Trimmer


Sorry, but I haven't solved any problem. I'm still waiting on the experts to solve my problem from June 16 on my trimmer not operating even with new fully charged battery. As for your replacement, I would suggest retail stores that sell trimmers, such as Home Depot, Lowes, Ace hardware stores or maybe B&D website.

My trimmer wont start. thought it was battery put a new one in worked for a few minutes and then stopped working


your batteries aren't charging fully, check them fully charged with a volt meter,, fully charged they should have a reading of 18.5 volts, if not they are not charging, and either the batteries have used up their life, or your charger is on its way out

My worx will not stay charged... the charger goes green after about 10 minutes and only runs for about 5 minutes...


it sounds like the battery has seen better days. a battery will get a "memory" and after while it could fully charged as far as the charger know but only hold a little charge. with the advices in batteries they shouldn't do this but they all do wear out of time. I would get a new battery, and everything should be just fine. With the any new rechargeable battery you want to make sure that you charge it completely and drain it the whole way before recharging.
Best of luck

My battery will not keep a charge it don't last 10 minutes/ i like the weedeater but it just don't last long enouh


I had one of these a while ago, the batteries are just cheap. Trimmers also use a lot of energy and battery powered ones aren't the best way to go if you want them to run a long time. I highly recommend replacing it with a good gas or plug in model from your local hardware store, they can help you find the right one to fit your budget. If you don't want to get a new trimmer you are going to be fighting dying batteries every year.

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 do I attach the machine to the wall charger when the protective cover prevents it fitting properly to the wall. Sticks out below putting it at an angle to not fit into the charger. Do I have to remove...


If you can't make the charger fit while the battery is attached to the trimmer, you can remove the battery pack (the whole black handle assembly) by pressing in the two orange tabs (one on each side) and sliding the battery pack forward off of the trimmer. Then you can plug the charger in and charge the battery wherever you want. It can be a struggle to remove the battery pack, but it does come off.

Hope that helps.

My weedeater with auto line feed will not stop feeding the line when in use.


Did you ever get an answer to this problem? I'd like to know because I have the same problem with my cordless 14" Black N Decker Gass Hog. I rethread it, but the line continually feeds and is out in about 2 minutes.
