Older types may have ‘NiCd’ printed on them but this has now been replaced by NiMH. Making sure the voltage of your replacement cordless phone batteries is the same is also important. Most AAA cordless phone batteries are 1.2V; never use non-rechargeable 1.5V batteries as this is dangerous.
How long does a cordless phone last
about 1 to 2 years
Is it bad to leave rechargeable batteries in the charger
One of the most important things you can do to extend battery life is to avoid overcharging. Disconnect chargers and devices with rechargeable batteries after the battery reaches full charge. Battery University recommends that nickel- and lithium-based batteries be stored with a 40 percent state-of-charge.
Do cordless phones work in power outages
Most folks will rely on cell phones if the power goes out, so make sure they are fully charged. If you have a landline phone from the phone company, you should still have phone service when you lose electricity. But if you only have cordless phones connected, those won’t work during a power outage.

What kind of batteries do cordless phones use
There are three kinds of battery chemistries used in cordless phones – Nickel Metal Hydride (NiMH), Nickel Cadmium (NiCad), and Lithium Ion (Li-ion), and there are a few major differences between them.
Do rechargeable phone batteries wear out
All rechargeable batteries wear out. The reason is that every time you charge the batteries you will lose a tiny amount of capacity and you don’t have any spare capacity to lose. In fact after a year of use, the batteries will probably only run the transmitter for 3 hours.

What happens if you leave a battery charger on too long
A: If you leave the charger connected continuously, even at a mere 2 amps, the battery eventually will die. Overcharging a battery causes excessive gassing — the electrolyte gets hot and both hydrogen and oxygen gas are generated. On sealed batteries, the buildup of gases could cause the battery to burst.
Why do batteries lose charge when not in use
Self-discharge is a phenomenon in batteries in which internal chemical reactions reduce the stored charge of the battery without any connection between the electrodes. Self-discharge decreases the shelf life of batteries and causes them to initially have less than a full charge when actually put to use.
