Frequently Asked Questions (FAQs)

1. What batteries do you use for cordless phones?

Nickel Metal Hydride (NiMH) Batteries: Nickel metal hydride batteries are a better choice to power up your cordless phones as they have a high energy density. They can offer up to 25% more capacity than NiCad batteries which means you can talk on the phone for a longer duration, if you equip them with NiMH batteries.

2. Can I replace the battery in my cordless phone?

Most cordless phones will take rechargeable AAA batteries, but it's important that you buy rechargeable batteries that have been recommended for cordless phones. A genuine AAA cordless phone battery has a slightly longer positive terminal to connect inside the battery compartment.
