will these BT1021 DC2.4V 300mAh work with the 800 mAh as shown or is it too much for the phone ?

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.

I am not sure but it did not work in my phones and I did not know who to return them to.

It should. The 800mah indicates that the charge will last longer. The larger the number the longer the charge lasts.

These work in my UNIDEN handsets which ask for a BT 1015 or BT 1007 battery. They also have a much longer talk life.

The batteries I received measured 2.5 by 1.75 by .125 inches. The charger specs indicate it will work for 220 volts. You will need an adapter for European style wall plugs.I have a HTC incredible 2 and cannot address the suitability for other models.

Hi Carla, the answer would be no, the voltages need to match. There should be a 2.4 volt battery version available. The ability of the battery to hold a larger charge (mAH) would be okay, as long as it still is designed for your device or phone. It needs to be an acceptable replacement for the model number of your battery and device/phone. In addition, if it is a different kind of battery, that is made up of different materials, for example Li-Ion/Lithium Ion or Ni-MH/Nickel Metal Hydride, make sure that the new battery has been approved for your device. Hope this helps Carla! If you're not sure, ask more questions.

My original batteries did not have mAh (milliamps per hour) rating, but the higher number just means they will last a lot longer without being charged. My old batteries had to be on the charger every day (even when new). These batteries last me 3-5 days before they even start to go down. I bought these batteries for replacements in my Uniden model # DECT1580 phones and am extremely happy with their performance - much better than the originals. Hope this helps.

The Google preview of this item shows "AmazonBasics AA High-Capacity Rechargeable Batteries (8-Pack) ... Ni-MH Pre-Charged Rechargeable Batteries provide the extra power you need . .... of about 2500 mAh, but two of the batteries are only 54-70% of the rating." but you are correct. When I click the link, that spec is nowhere to be found. I use these for wireless microphones at my church. They work great. The nubs are slightly short so I do have to seat them in really good but they are excellent.

We bought this battery for a Uniden cordless phone and it works very well. The model number BT-1008 is 2.4V 800mAH and the replaced battery was 2.4V 300mAH and the new one holds a charge longer then the factory standard model and I can give this replacement a big thumbs up. EW

I ordered two. They work perfectly. The higher 2400ma means they have more capacity - last longer. However, be careful when ordering. There are two different models with the same part number. Insure that the contacts in the picture looks exactly like the contacts on your current battery.

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

I have been using them on a 1000mA and a 1300mA charger for my Android Incredible. I have the original 1300mAh battery and also have a heavier 2150mAh battery. Both have charged with no problem so far, using a 1000mAh 115VAC to 5VDC Usb charger.

Lynda, I did a quick search and found that a Uniden Battery BT-1021-BBTG0798001 is advertised on Amazon as an alternate for the BT-1021. However, if I were you, I would contact Amazon for more help, because there are just too many unknowns for us consumers to decide which alternate is the proper one. BTW, check your specs.; I think the 300 amps is really 300 milliamps. If I'm correct, then this battery may be just what you need. Copy the following link and past it into your browser NEW!

I don't know as I have a ATT phone and the battery model is BT8000/8100. Good luck.

It should. mAh stands for milliAmp hours, it is a measure of capacity. BT1021 are 2.4 V

I purchased mine on April 11th and it says on the battery it is 7800 mah. I'll post pics.

Can't say for certain. Best bet is to match the Volts rating and connector head. "mah" I believe just means how long it can last. A real electrician can comment on that. You can also google the original battery model to see if this one will work with it. Multiple Uniden handsets used the same model of battery from what I remember when I looked it up. Best of luck.
