FAQ about Rechargeable 6V Battery

In what way can you charge a 4v Rechargeable battery fast using a 6v source? In what way can you charge a 4v Rechargeable battery fast using a 6v source? I mean if we add a resistor here or there or any other device in the circuit will we able to improve the charging speed. please do suggest any ways...... This depends on the chemistry of the battery. Nickel-based batteries can tolerate a lot of abuse; you could just connect the + to the + and the - to the -... It will likely charge VERY fast. If your 6-volt source is limited (such as a wall transformer), it may take a little longer to try. Heat will damage a nickel-based battery, so if any is detectable, stop the charge! A nickel-based battery is usually fully charged by the time it starts producing heat.
For a safer, less exciting, but still fast charge, you need to know the capacity of the battery. Assuming your six-volt source can keep up, the resistor formula for the desired resistor is approximately this:
ohms = (chargeTimeInHours * voltageDrop) / batteryCapacity
So, if you have a 1Ah battery, a 2-volt voltage drop between source and battery (6 - 4 = 2), and want to charge it in 1 hour: (1 * 2) / 1 = a 1-ohm resistor, assuming the battery is fully dead.
The above applies to all battery chemistries, BUT, if the battery is a lithium battery, I would strongly recommend against any kind of charging without a proper charging circuit. If the battery becomes overcharged, it will likely violently catch fire.

How can you tell when a rechargeable battery pack (9.6v) is fully charged with a standard wall charger? How do you tell when the battery is fully Charged. Do you have to wait until it gets warm or very hot. How hot or warm should it get after taking it off charge? Some chargers have a red light on the charger, when the light turns off the battery is charged.

What's the highest mAh Li-ion 3.6V rechargeable battery available in AAA? Im looking for a Li-ion battery in AAA size (diameter only, it can be up to 65mm long) with the highest mAh. Must be rechargeable. Thanks! Due to the chemistry involved Li-ion batteries aren't available in conventional battery sizes.Li-ion are also always 3.6V, would be too high a voltage.
The highest capacity AAA size (Nimh) available are 1,000mA.

Can you use a rechargeable 9.6v battery in a rc car that uses 7.2v? I have 9.6v rechargable battery and i want to use it in a rc car but on the box it says that it needs a 7.2v recharable. If i use a 9.6v in this car will it over heat or will it work without damaging the car. Both batteries are roughly same size. Will a higher voltage battery make the car go faster. thanks. The voltage is close so that if it fits, you can try it. Most small RC motors have a wide range of voltage that is acceptable. Give it a short test and the check for excessive heat or smells.

Does anyone know how long a 3.6v, 900Mah cordless rechargeable battery suppose to last? ? I have had my Uniden CLX465 for three years now and I had to change out the battery probably 3+ times. The battery life just gets shorter and shorter(maybe after 1 year of use, it just depletes after 10 mins of talk time). Is this normal? I am buying replacement batteries from Ebay and they are not the original. Can someone tell me how to increase the battery's life span. Thanks in advance, -Ling Original batteries or not, it doesn't matter. Batteries are all the same the only difference is that the "name" brand batteries have just that, a name brand sticker slapped on them. Other then that .. That is the only difference. You can get the same batteries for cheap by going here:
http://www.needbattery.com/Cordless-Phone/Uniden/CLX465.html To make a long story short, a 900 Mah battery should last about 6-7 hours of talk time.

is a 3.6v AA rechargeable battery good, decent, or really good? i was going to get these.. http://cgi.ebay.com/Ultrafire-Rechargeable-14500-AA-Lithium-3-6v-Battery-x4_W0QQitemZ370321791321QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item5638e61959 and this.. http://cgi.ebay.com/UltraFire-Charger-for-Lithium-AA-AAA-batteries_W0QQitemZ390032239724QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item5acfbbac6c what i want is rechargeable batteries that will last really long in my camera/ xbox controller/ anything AA thanks alot.. that earns you best answer.. as soon as i can do it the v isn't what you want to look at what you want to look at is the mAh.
those are 900 mAh which is just terrible.
Good ones are in the 2000-3000 mAh range
I have these and they last a long time

this charger will probably do (comes with some more batteries)

Do I need the spyder rechargeable battery for my spyder rocking trigger or can i just use any 9.6v battery? I bought my spyder rocking trigger and it didn't come with the rechargeable battery so i put a regular 9.6v battery in it and it says it has a low battery and automatically turns on safety if you shoot too fast... It was a brand new battery so I know it wasn't a low battery... If thats not the problem ten cam you tell me what you think it is??? Thank you for your help... The Spyder RT should work with a 9.6v battery and you don't neccesarily need a spyder rechargeable battery. If it doesn't work with a regular battery try a different one or try a different brand. If it didn't come with a rechargeable battery, that means you don't have to buy one. Just in case, try checking the manual and see what it says. Is the gun used?

How can i fix a AAA rechargeable (AA 500mah 3.6V) battery that doesn't hold a charge? I had a rechargeable battery which i was using in my remote controlled car. it was working pretty well but not it has stop working! :( i wont hold any charge! they were three combined with each other in a circuit, but when it stopped working i broke the circuit and uncombined them. Is there any way i can make it work again? Nothing lasts forever. Time to "BUCK-UP"! & buy a new one

How do I charge my phone battery (input 100-240v) with a lead-acid rechargeable battery? (6v each)? and how do i convert direct current to AC?? I don't know. How do you do these things?

would i fry my virtue board on my spyder if i used the rechargeable 9.6v battery? this is for paintball gun.? alright, so, I'm ordering my virtue board, and i was thinking about using my spyder rechargeable battery, which is a 9.6v, and the battery that the virtue uses is a 9v, does this mean i have to go buy a 9v rechargeable battery? cus i wanna get a battery thats rechargeable please help! the 9.6 volt battery in a spyder is $13 other rechargable batteries are cheaper so no it wont hurt the board the spyder batteries are no different from the others
