I have been a customer of Telephones Online for many years now and have had great experiences with their customer services; I have received sound technical advice in choosing a cordless phone and been the recipient of unwavering support when I have had a problem with a telephone. The first time the unit, as I remember, had been purchased as an additional handset for an existing telephone but turned out to be incompatible, the second was because the phone had arrived without batteries, this caused a problem, but they were swiftly and personally dispatched for delivery the next day.
Cordless phone batteries are extremely important for the overall performance of a DECT phone. they will naturally influence both standby time and talk time, but also have a bearing on the range you can get from a digital phone. Many people would be surprised to know that the standby time of a battery is inversely proportional to its distance from the base station – this being due to its constant need to maintain a connection with the transmitter in the base.
Early digital phones used Ni-Cd (Nickel Cadmium) cells which tended to deteriorate quite quickly, these were often expensive to buy as they were manufacturers own and hence priced accordingly. Many of these early cordless phone batteries had teething problems and were the cause of many a complaint. More recently it has become the norm to supply handsets with generic rechargeable NiMh ( Nickel Metal Hydride ) AA or AAA batteries. These are available in many shops and even newsagents as they are used now in many household goods such as digital cameras and the like. In general the ampage of the battery will determine its length of charge maintenance, though many handsets will not be suitable for higher power batteries.
The more modern batteries supplied with cordless phones do not have a memory, and hence, no longer require such a long initial drip charge on initial use as per the old style, where one was recommended to leave them overnight for full lifetime battery performance.
