I have a D battery that's dead and I don't have a dumb charger to bring the charge up enough for this to recognize and charge it. How can I charge it?

Smart chargers need to sense voltage to start charging. Get a battery that is fully charged and hold a small wire to each end of it with your fingers. Now put the "dead" battery in the charger and touch the ends of the wire to it from the good battery. The unit will sense power and start charging the battery you thought was dead. This happens if you let them sit dead too long but the batteries are usually still good.

Smart chargers need a trickle of power left in the battery to charge it. It's simple enough to jump start them. Why smart chargers never have a "jump start" button is beyond me. To jump start a dead dead battery that won't charge, get another charged battery of the same size. Hold the batteries together so that both of their negative (flat) ends are touching. Then take a wire, or some other conductive device such as metal tongs, and make a connection between the two positive ends. Keep the positive ends connected for 5-10 seconds. That will add enough juice to the dead dead battery for a smart charger to recognize and charge it. Smart chargers need a trickle of power left in the battery to charge it.

I didn't know that could happen unless the battery had reached its maximum number of re-charges. If the battery is too old, replace it with a new rechargeable. I have found that Radio Shack batteries are not very reliable, but have good luck with other brands.

Try this. It gets the charge up so your smart charger will recognize it. www.youtube.com/watch?v=ICne0ZyZ3IA

As most have already mentioned jumping the battery is ideal, using the trick in the youtube video that a user posted here is the ideal option. However if you find this is happening chances are that cell is giving out. I had one cell that wouldn't jump probably because it's at the end of it's life. Most good cells will recover enough voltage, i never seen a healthy cell resting at 0 volts, maybe unless it was in storage for too long.

I have had this charger for a couple of years now and have never put a battery in it that it didn't recognize. My guess is that your D battery is broken inside and doesn't make a complete circuit. This is a very good charger and keeps my 12 (AA), 12 (AAA), 8 (C), and 4 (D) batteries fully charged. Rechargeable batteries are a little expensive, but this charger saves a lot of money in the long run. I live full time in an RV and can't run to the store for batteries all the time from the middle of the Arizona Desert. Rechargeable batteries don't last forever.

I have never tried it with a fully dead battery. My understanding is that if you have a fully dead battery with dead cells, no charger would help. This unit should bring back a mostly discharged batter, although it will take a considerable time because of the low amperage. A higher amp manual charger would get the battery charged faster.

You can charge it with the USB connection for its original AAA rechargable battery. Of course, you can charge or replace the battery at your convenience.

Take the battery out for five minutes. Pres and hold the power button for 30seconds and but the battery back in. Turn the device back on and it should began to power up and charge.

You stick the charging part of the cord onto the battery stick and put the bigger part of the cord on the computer or you can buy a cube and connect it on a plug and a red light should show up when its charging hope this helps!

I also have DC9700 charger and the battery charged without any difficulty. Also no idea what the difference would be with an A model charger.

There is a small hole on the side of the flashlight and should be a smallRubber plug in the hole just pull it out and plug in the charger. I was so surprisedat how little time it took to charge it.Hope this helps.

I bought a charger and additional batteries from Battery Junction. Here is a link their website: http://www.batteryjunction.com/

Nope. This might be a knock off styled battery charger, or the batter itself might be broke.Do you have any other batteries to try out to see if it's the charger itself or the battery? Someone you can borrow from?Do some testing to pin down what it is that isn't working here.Good luck.

You don't. It's a recharging unit. When it no longer charges you throw it away and get a new one. My last one lasted two years.

Buying a battery might be a cheap fix. Make sure the charging unit is plugged in and it lights up when the unit is placed in the charger. If the unit is new, send it back.

you put the negative end on the lower connector on the charger, line it up with the positive connector and push down gently. The battery doesnt lay down totally flat but it will make the connection you need to charge it

I'm afraid I can't help you as this was purchased for a friend who's battery died. The charger was used over night then unplugged.

There is a little rectangular battery charger that exactly fits the battery. I also was able to find a universal one at a Sears store that fit it when I had forgotten the charger on vacation

There are no instructions. You simply place the battery (with the metal ends)in the charger against the metal prongs. Pull out the plus on the charger and plug it in.

My girlfriends did the same thing, and what I did was drain the battery down using the led light. Once it was almost dead I charged it for 2 days, and now it seems to be working fine.
