the batteries in my phone are labeled 300 mAh. Will it be ok to use these at 400?

Dear, if the battery can be installed into your phone well, so you can use the battery with no problem. Please contact us freely if you have any questions. Thanks a lot.

Obviously a 1900 mah has about 10 per cent more power stored in it, but this battery will not rit into a Galaxy Rush, so forget it, if that is the phone you have.

I agree with Samantha. They are 900 mAh and 2.4 volt capacity so they should work fine.

Depends on your charger, and how much capacity the batteries actually have (most Ultrafire batteries have false mAh markings). I wouldn't buy these, all except for one I've ever heard of were bad batteries, and even that purchaser found the capacity was 2000 some mAh. I'd find some Panasonic 3100 or 3400mAh protected batteries instead, these Ultrafires are not worth it.

Either will work fine. I leave mine on 500 since I'm usually not in a hurry for my batteries. Add a guideline you generally charge lithium ion batteries at one half capacity per hour, unless otherwise specified by the battery manufacturer.

If your phone takes AAA batteries these should work perfectly. My phones (model KX-TGA641) told me to charge for 7 hours after I installed them. These batteries brought my phones to "like new" again!

Assuming that either battery will physically fit the phone, the critical specification for working on the phone is the DC2.4V voltage rating. The 300mAh or 800mAh rating gives the storage capacity of how long it will work until the voltage level drops to the point that it needs to be recharged again. Of course, the higher capacity rating means that it will work longer before needing to be recharged again.

You would have to check with B&D.; I looked on the battery and the box it came in and could not find anywhere what the mah rating is (which is kinda strange). I can report that they do last a long time.

Yes, as long as the voltage is 1.2V the 800 MAh. fully charge last longer than the 400 MAh hope that information helps.

Yes absolutely, they will last 3 times as long in use. mah is mili-amp - hour. it means the amount of current available in 1 hour, if the phone needs only say 200 ma to operate, it will last 9 hours with a 1800 mah battery or 2.5 hours with a 500 mah battery

Maybe, but it depends on the voltage requirement of the device. The battery is a 33Ah battery that can produce 15-20V depending on the settings. They claim 125 Wh. The formula to convert Wh to mAh is mAh = (Wh 1000) / V. So, we have 33,600 = (125 x 1000) / V. This gives us a V of about 3.72 V if their 125 Wh number is correct. On the other hand, if the 125 Wh number is the correct value at say 15V, that would mean that mAh = (125 x 1000)/15 or 8,333 mAh. So, as you can see, there's something screwy with their measurements.

In the batteries, under + and size AA you can read 2300 mAh. It's true ??? I don't know exactly

Depends on whether you buy a reputable brand battery with accurate current rating at this drain rate. Most 4000mAH cells are not rated correctly and will be a disappointment.

These are HHR 75AAAB. I assume they are the same voltage, but hold a different amount of energy. If you use them, make sure all the batteries in a stack are the same kind.
950846
as far as I know , you can.. The more mAh increases the time the phone will last before needing recharged... Voltage must be the same
1588798
Yes! I will work just fine. My experience with these Batteries is excelent. They last as long as the originals

The batteries are 18V and rated at 54 Watt Hours. So in terms of mAh this would be 3000mAh or 3.0 Ah. However, comparing this to a AA battery that has 2800 mAh (a common size) at 1.5 volts is not very meaningful. Be sure to compare batteries that have the same voltage output.
