To fully enjoy these benefits that come with owning a cordless phone and prevent infuriating instances like a missed call or your call getting cut short from occurring, you will need to invest in the best battery to power your cordless phone.
Types of Batteries used in Cordless Phones
Initially, the manufacturers used Nickel Cadmium (NiCd) batteries in cordless phones. However, the use of Nickel Metal Hydride (NiMH) to power cordless phones has recently gained favor due to their reliability and durability instead of nickel-cadmium, which tends to lose capacity over shorter periods. NiMH has been credited for the longevity that is crucial for cordless phones’ operators. There are also Lithium-ion and Lead-acid batteries on the market. These batteries you can find at amazon.com, for instance, the 2 Pack Panasonic NiMH AAA Rechargeable Battery for Cordless Phones shown below.
Nickel Metal Hydride batteries (NiMH) are the best choice for your cordless phones as they have a high energy density and long durability. The NiMH batteries have approximately 25% more capacity than Nickel-Cadmium batteries, and they hardly require exercise cycles. Furthermore, the Nickel-Metal Hydride batteries are less prone to memory effects, unlike Nickel-Cadmium batteries. The Nickel Metal Hydride (NiMH) batteries for cordless phones are also environmentally sound.

When replacing the batteries for your cordless phone, ensure that they are of Nickel Metal Hydride type and are AAA rechargeable batteries. Please note the replacement battery’s voltage as it should be the same as that of the original battery’s voltage. The voltage should ideally be 1.2V; a battery with a higher or lower voltage may damage your cordless phone.
It would be best if you withstood the temptation to replace the original battery with a higher capacity, as this may cost you in the long run. The charger that comes with the cordless phone has an inbuilt charging current that can’t change; hence when you use a battery with a different capacity on your cordless phone, it may not charge the battery appropriately.

The batteries will practically work over a range of 50mAh to 100mAh below or above the nominal capacity.
It is recommended that the batteries used in cordless phones are changed annually (after 12 months). Given a proper maintenance, the batteries can last longer than that. However, you should immediately replace the batteries when you notice a reduction in talk time.

Frequently Asked Questions
What can I do with the old batteries of a cordless phone?
Instead of throwing them away, you can take them to the nearest supermarkets with battery recycling bins and do away with them in those bins; this is a very environmentally friendly way of getting rid of worn-out batteries.
Is it okay if I keep my cordless phone on the charging device after being fully charged?
No harm can be experienced to the battery when you leave the cordless phone connected to the charging unit after it is complete. However, just because you can leave it connected to the charging unit doesn’t mean you should. Leaving cordless phone batteries connected to the charging system after being fully charged can result in overcharging, shortening the battery’s lifespan, and damaging it.
What signs do you look for to see whether your cordless phone battery is running low?
A higher percentage of cordless phones will send a unique beep through the handset at regular intervals to alert the user that the battery is running low. This warning is intended to alert the user that the battery’s performance may be deteriorating and that the quality of calls may suffer. The cordless phone battery may only sustain a call for a few minutes after the beeping starts.

Phones also have a battery-life indicator, commonly a series of bars or bands that fade out one by one as the battery life diminishes. The words “low battery” or a flashing icon will appear on cordless phone screens as a visual confirmation of the low-battery chirp indication. Because they aren’t visible unless the phone is held away from the user’s ear, these visual indications are secondary to the chirp signals.
