High-Energy-Density
Each Synergy Digital Cordless phone battery has the capacity to provide long-lasting, continual use. Boasting a high-energy density and high-power capability at a more constant rate, these batteries are made of Nickel Metal Hydride to provide long-lasting, reliable power. In fact, the high hydrogen content of Nickel Metal Hydride is double the battery capacity compared to nickel-cadmium batteries.
Long-Lasting Power
Using these powerful Synergy Digital Ultra Hi-Capacity Cordless Phone Batteries, you can keep your cordless phone consistently powered for longer periods of time. A Ni-MH battery delivers substantially more current than any other battery in its class, boosting performance when servicing high-drain devices. In addition, each Synergy Digital battery is made with high-quality Japanese cells to ensure long-lasting use, so you never have to worry about draining off the battery the moment you really need it.
Long-Term Value with Less Waste
These Synergy Digital cordless phone rechargeable ultra-high capacity batteries can be charged over and over thousands of times, so there is less waste. Simply charge your cordless phone with the battery inside – and enjoy ultra-strong power for your device time and time again. Not only do you get more bang for your buck, but Nickel Metal Hydride is also free of toxic heavy metals. As such, these batteries are recyclable and safer to use.
Compatible with your OEM Battery
Synergy Digital Batteries are compatible with the original OEM battery. Its ultra-high-capacity provides longer-lasting use than the original OEM battery. Therefore, you can rest assured that your cordless phone will perform at its highest standard possible.

I was attracted to these batteries because the Amazon page clearly states, "Made with high quality Japanese cells." The manufacturer's detail page emphasizes that, in similar words.But the labels on the batteries say "Made in China." I thought I was getting top-quality Japanese batteries, not slave-labor polluting Chinese batteries, and I'm irritated at the seller's misrepresentation.

Perfect fit my for 14-year AT&T landline phone system model: TL’s 74108, 74208, 74308, 74408. Only bought 2 batteries as the other cordless handsets had become inoperable (it’s 14 years old). It initially took about 24 hours to fully charge but they are now perfectly fine and I’m very satisfied with them.

I ordered from this provider because my former source was no longer available on Amazon. I can’t say anything about longevity at this point, because I have not had the batteries that long. But other than that, it all seems very good and has performed completely well as expected.

These battery packs fit our cordless phones that we have had for years. I did not want to purchase a new cordless phone system so we searched for the battery packs to see if that was our problem and it was. Phones are working like new. Very glad we were able to find and purchase these battery packs.

I received the batteries in good packaging and everything in order. I installed them with no problem in my phones and they now work beautifully, the charge is longer, no interruptions in reception, a big improvement from old worn out batteries.
