Black and decker older batteries don't keep a charge. Very poor quality. You can't get them to work any better than they do. You need to replace will the new ones they sell, made better. But cheaper to buy new tool with batteries included.

    If yours are less than a year old, they are still under warranty. Call Black and Decker and tell them. They should replace them being under a year old. My batteries where around 1-2 years old. A battery will charge on the charger till it thinks it is charged. The charger light will change color. You can leave on the charger all the time, when a battery is charged and you remove it, it starts to loose power even when not using it. Try leaving one on the charger, see if this helps, when you remove to use put the other one on charge.

How long to recharge a 18v dewalt drill battery


A fully working 18v Dewalt Battery will only take 90 minutes to just over an hour to fully charge from going flat. This fully charged battery should last about 4 hours of use (depending on the load). So the answer is 1 hour.

My makita batteries nolonger charge


Lithium batteries do have a life span determined by how many times the battery is discharged and recharged and how hard it is worked on the tool. Batteries get hot while charging and discharging and heat is what ages batteries. Lithium batteries, depending on usage, will last from one to three years. I've seen some last five years but that's rare. They also have numerous cells and a circuit board that can go bad and kill the battery. Chargers are designed to check the battery's condition and won't charge a battery if it detects something wrong. If your battery is under one year old, it's covered by the warranty. If it's over, you'll have to buy a new battery.

Rechargeable batteries do have a lifespan, they won't recharge forever. If you have fully discharged the batteries then fully recharged them and they still don't have full power or they only last a couple minutes then they are done. If they won't charge or the charger shows them as defective, the only fix is to replace them.

My dewalt 18v xrp battery wont take a charge


Depending on how old or more to the point how many times you have already charged the battery, it may be worn out. All rechargeable batteries do reach a point where they won't charge up anymore. If you have fully discharged the battery and tried to fully charge it up again and it won't take a charge or only lasts a few minutes on a charge it may be time to recycle it and buy a new one.

The battery will power your equipment for 30 to 45 minutes, that is normal. What you're thinking of is the lifespan of a lithium battery. It with your battery will last 10 times longer than a regular NiCad battery. So you will be able to charge the battery and use it Hundreds of times before the Battery Life is depleted. Sounds like it's working as designed

Battery will "fully" charge and then only run for 20 - 30 minutes of use then be discharged. Have fully discharged and re-charged to no avail. My other battery will run for 2-3 hours of use.


Hi Fred,

I have several 18v tool sets and for the most part I'm quite satisfied with their performance. I currently use Bosch and Ryobi.

When used with the drill, a battery can last me the whole day. On the other hand, the sawzall will eat them up pretty quick.

The thing I've found common to all brands is that it is absolutely crucial to make sure the batteries are fully charged before they get used for the first time. That first full charge seems to set the bar for subsequent charges for the rest of the batteries life.

I too, have tried the discharge/recharge thing. No help. I can only suggest a new battery and letting get all it can take from the charger the first time out of the box.

Since I've been doing that, I rarely even think to bring my charger to job sites, there's that much of a difference in performance.

Hope this helps you out.

Best regards,
Mike

Battery doesn't charge


When you connect the charger, if the light goes to red to green within a few minutes and the battery power does not last more than 1-2 hours or less, it may indicate that that the batteries will not take a charge anymore and need to be replaced. This can happen if the power chair has not been charged in a while or has been stored. Having the chair on or off while charging will not affect the charging process, but you ususally want it to be OFF.
Good luck!

Both green and yellow light stay on and batteries will not charge 18v


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.

Solution is two fold. Will try the freeze and re charge approach today and do this a few times. The long term soluiton is to purchase two Lithium batteries and a duel chemical charger. Expensive solution but seems it will work.
