I have craftmans19.2 volt battery and it wont recharge and charger is working find. can you resurect the battery so it can be recharge and how and what tool i need to use

Most charger systems for recharging batteries will not recharge a dead battery. But you may be able to bring the battery back to a voltage high enough to get the charger to work. Find a battery drill with the same voltage. Take small alligator clips and hook the battery up positive to positive, negative to negative to your same voltage dead battery. Leave it several hours till the voltage grows in your dead battery. Then try the recharger that came with the bike battery. Don’t leave the batteries inside while you are doing this.

HI,

If your phone is still under warranty the best solution is to get it replaced.The problem is actually with the port of the charger.I mean the hole in which you plug in your charger isn't working properly.Where as your USB port is different and works properly so it charges the battery.So you will have to get this repaired.

MetroKane E RABBIT portable rechargeable battery wine bottle cork screw. I need a replacement battery. Present battery in it is recharable group of three batteries spot welded together with bridges recharged by a 8.5 volt charger. Each of the batteries are the size of a AA standard, with no raised end to designate polarity. Using my VTRr, with no load I get 8.5 volts. Each cell alone reads 3 volts.

The present batteries will no longer hold a charge strong enough to run the Cork screw.

Thanks for your assistance.

take it to a yamaha service center and have them check the voltage output of the charger system
if it chargers more than the 14.5 volts for a 12 volt battery or more than 8 volts for a 6 volt battery , that will explain the causes of rapid battery failure

You need two 12 volt batteries in series for your charger to work. If the batteries are both flat then use an automotive 12 battery charger to recharge them individually. It may take several days to get them back up enough for the 24 volt battery charher to start working again.

if it is a digical if so the batteries have to be rechargeable and be over 1000 because the rest just arnt good enough . because of the technolgy in the camara , and because of what it can do do . the batteries have to be the best . their will be more power comeing out of the camara and excceds the battereis. its like a mobile phone , the phone is a 16 volt batteri and you plug a 5 voult charger in the phone . it gets realy hot because their is insufficaint charger for the volt . we wiill have almost blew the charge on the batteris aswell as the connection on the camara or ie [phone]. leave for 24 hours and then try the rechargeable energizer 2000 plus is one of the best .replace the old for new and try the enegizers

check tha battery and charger with a multimeter and make sure they are showing at least 12 volts

it could be a fuw thigs doing this
to many start ups and no running time to recharge the battery up,,,

dud battery ,,wont hold charge,

bike charger not charging the battery up,,,

voltage regulator leaking battery volts back into charger when motor is not running

burnt out or dud rectifier,,,not charging battery or leaking volts back into charger,,

also too many lights fitted for charger to keep up with the extra load needed,

or matbe even that new "**** warming seat" is killing the battery??? hmm?
not an easy thing to answer

yep check it with a multimeter and it should show between 12-14.6 volts

jpierre's solution (in another thread) was right on the money. Touch the positive (+)end of the 9v battery to the positive (+) end of the camera battery.Leave them touching for a few seconds (10 seconds should be more thansufficient). Seems these lithium-ion batteries are subject to a'digital memory.' Subjecting it to a volt surge almost three timeshigher seems to clear it.

In short, it works like a charm.
