AAA Cordless Phone Batteries

These rechargeable AAA Cordless Phone Batteries are NiMh rechargeable cells designed specifically for cordless phone handsets. They are a high quality replacement for the original cells fitted by the telephone manufacturer. As such they will improve performance including increasing talk time and standby time between charges. Please choose the batteries with a capacity closest to the cells in your handset, see below. If you are not sure please email us and we will be happy to help.

How do I choose my rechargeable phone batteries?

When choosing rechargeable aaa batteries for cordless phones it is important to select the batteries that have a capacity closest to your original batteries. The capacities shown are called nominal capacities, in practice they will work properly over a range of approximately 50mAh to 100mAh above and below the nominal capacity. NiMh stands for Nickel Metal Hydride and describes the chemical makeup of the batteries. It is important to use the same chemistry of rechargeable batteries in your phone.  You can read more on this by clicking on the product and then additional information.

BT recommend that you should change or replace your phone handset batteries every 12 months. In practice in a domestic environment our batteries will last considerably longer than that. When you notice that the talk time is reduced it is time to replace the batteries.

The rechargeable AAA cordless telephone handset batteries that we supply are high performance products. You will find that after several charge discharge cycles you will benefit from longer talk time and standby time between charges.

How do I prolong the lifespan of my batteries.

Your AAA NiMh rechargeable battery is charged during production in order to test it. Your battery will discharge between the end of the production and the moment you receive it. That is why your battery will have to be charged before you use it. You must use your cordless phone to charge your new AAA battery for 12 to 24 hours before using your phone; this will prolong the life of your battery.

Rechargeable aaa batteries for cordless phones will discharge slowly when not in use. The self-discharge rate is about 1% of the battery’s capacity per day at room temperature. The higher the temperature, the faster your battery will discharge. If you intend to leave your battery for a prolonged period without use then a service charge is recommended. Simply take in to account the self-discharge rate and time between use. You can read more about how to maximise the lifespan of your new NiMh rechargeable battery here.

Selecting the Best Batteries

You are in the right place if you need further information please email us and we shall be delighted to help.

NiMh AAA cordless phone handset batteries have a 6 month shelf life (See What Panasonic say). This is why you should only buy batteries that you are going to fit to your phone and use. Or in other words do not buy spares. It is also why you should avoid end of line products or stock found on or in certain non-specialist websites or shops.

In conclusion when you receive the new AAA rechargeable telephone batteries you should follow the guidance and charge them for 24 hours before using your handset to make calls. For full details please refer to the articles page.
