Without the proper charger you could damaged the phoneand or the battery, attempting to charge it with out the proper regulated charger is not advised. you can find an aftermarket charger for alot less money than it would cost you to replace the phone because of damage. incidently because most batteries are either nickel-cadium or lithium ion you could potentially explode a battery by not using a proper charger this would result in a painful injury.

Battery went dead put charger on battery and charger shuts off.


the reason for this may be the way you have attached the battery charger leads
charging batteries require the positive lead of the charger to be clipped to the positive terminal of the battery
likewise the negative lead of the charger goes to the negative terminal of the battery
I suspect that you are hooking positive to negative in which the charger will go into overload protection and shut down.

My nokia 6288 is alway getting hot why? And what do i do


Any history of water damage? is the battery already deform or blowing? the phone might turn into some kind of shortage that is why it is getting hot, or the battery voltage is already open and needs replacement.

By the use of multi-tester, you can testify if the phone is shorted or some short circuit board,please follow this steps

* on your phone,locate the positive and negative terminal of the battery connector,usually both ends is the given polarity(facing at the back of your phone,positive is in the left terminal and negative would be the right terminal)

* on your multi-tester,switch the selector to Rx1 (resistance)

* using the red pin (positive) of the tester,hit the negative terminal of the phone.
* using the black pin (negative) of the tester, hit the postive terminal of the phone.
* if the tester meter don't respond,it means the phone is normal and that's the time you need to replace a new battery.
* but if the tester meter raise high or even a little,that means the phone is in short circuit problem,again,if the phone is water damage,dismantle the 4 screws at the back of your phone and release the back cover,carefully remove the flex connector attach,now lift up the pcb or motherboard,clean it pcb using any rust solution and toothbrush,dry it after,now assemble the phone and make a test again.

* if the phone still got meter rating on the tester,better bring the phone to a mobile service center for a complete diagnosis and troubleshooting.

Thank you for using Fixya...

When I swtch on my nokia 6303 classic it say battry low and it beacome off I want hole formate code


p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 5.5px Helvetica} p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 8.0px Helvetica}

I found this information in the manual, I I think it should address your problem:


The battery can be charged and discharged hundreds of times, but it will eventually wear out. When the talk and standby times are noticeably shorter than normal, replace the battery. Use only Nokia approved batteries, and recharge your battery only with Nokia approved chargers designated for this device. Use of an unapproved battery or charger may present a risk of fire, explosion, leakage, or other hazard.

If a battery is being used for the first time or if the battery has not been used for a prolonged period, it may be necessary to connect the charger, then disconnect and reconnect it to begin charging the battery. If the battery is completely discharged, it may take several minutes before the charging indicator appears on the display or before any calls can be made.

Always switch the device off and disconnect the charger before removing the battery.

Unplug the charger from the electrical plug and the device when not in use. Do not leave a fully charged battery connected to a charger, since overcharging may shorten its lifetime. If left unused, a fully charged battery will lose its charge over time.

Always try to keep the battery between 15°C and 25°C (59°F and 77°F). Extreme temperatures reduce the capacity and lifetime of the battery. A device with a hot or cold battery may not work temporarily. Battery performance is particularly limited in temperatures well below freezing.

Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object such as a coin, clip, or pen causes direct connection of the positive (+) and negative (-) terminals of the battery. (These look like metal strips on the

battery.) This might happen, for example, when you carry a spare battery in your pocket or purse. Short-circuiting the terminals may damage the battery or the connecting object.


So, essentially, you probably need a new battery.


Good Luck!

By blackberry flip turned off in the middle of a call and I have not been able to to turn it on since. I changed the battery and that did not work. Any ideas?


it may be that battery is faulty, and is not charging.

A standard cellphone battery can support a charge from near empty to full about 300-500 times. after that, the charge is not 'filling' the battery, and it is drained quicker.

You can test the ability of the battery to hold a charge.


1. Plug the cell phone into its charger and plug the other end in to an electrical outlet. Allow the battery charge to full capacity.

2. Press and hold the power button on the cell phone to turn it off. Let the phone power down and remove the back cover to access the battery.

3. Remove the battery and observe the label for the voltage. Most cell phone batteries are 3.4 to 4.5 volts.

4. Turn on a multimeter. A multimeter tests current flow in voltage and amps and also resistance in a circuit. Place the black test probe on the negative battery contact and the red test probe on the positive battery contact. The contacts are on the edge or bottom of the battery and should be marked negative (-) and positive (+).

5. Place one test probe on the left terminal and one on the right, if the battery terminals are not marked. These are usually the correct terminals and the meter will show a positive reading. If the meter shows a negative reading, move the left or right probe to the middle terminal until one pair shows a positive reading.

6. Read the display on the multimeter. The voltage should be the same or a little higher than the battery label due to the fact that batteries hold an additional charge above the full charge mark when they have just been charged.


You can go to your local mobile store, and ask them to try another battery in your phone. if it works, great, you just need a new battery.
If not, well, the phone might have water damage, could have a circuit shorted out or something unusual. eitherway, if the phone doesnt turn on, you need to take it to the vendor, who has resources to test the equipment.

make a friend with someone who also has a Blackberry 8220, maybe you can try their battery for free, and if they arent looking, pull a switcheroo!

Battery cannot charge


hi,

here's what you can do...

Check the charging terminal of your unit and look for dirt accumulation and the like that maybe blocking the metal part or the terminal, remove it if any.

If there is none and surface is clean, chances are that you have a defective charger or your unit has a defective charging circuit and will not charge your battery. aslo try on charging on other outlet.

To check your charger, you must have a multi-tester and set it to 10 Volts dc. connect the red probe of the tester to the positive terminal of the charger and the black to the negative. it must have a reading between 4V to 8V if it is OK. if it has a negative reading, reverse the connection.

if charger is OK, most probably that the charging circuit has problem.

I recommend to have it fix to a repair shop to avoid further damage on the unit.

Hope i helped you...
Don't forget to rate me OK... Thanks...

Phone was working, when the battery was very low, i switched it off to get the sim out of it and when I put back the battery to switch it on.. it doesnt want to start. Its been dead ever since, any chances...


Hi!... I think your battery is very drained. Try to "shock" the battery first. If you have a DC supply at home, set the supply at 6-10V then Put the negative terminal wire to the negative terminal of the battery and in a snap put the Positive wire to the Positive Terminal of the Battery. Then put your battery back to your phone and charge it. It will probably be ok.

Cant get phone started


You may have let your battery fully drained before you recharge it. If that is the case, it will never charge and turn on the unit. Using a voltmeter, check the voltage. Any voltage lower than 3 volts will not allow your battery to be charged no matter how. You need to "shock" it before you charge it. To do so, use a 9 volt battery and connect its terminals to the battery terminals with same polarity. That is, positive to positive and negative to negative. Do this for one minute or until the battery gets warm. Insert the battery then charge. If it successfully charged but dies early, you need to replace the battery. You may opt to borrow a friend's battery to directly check if it's really the battery.
