Can you imagine paying upwards of $20 for a AAA battery pack for a cordless phone? I couldn't so I bought 6 of these and rebuilt the battery packs. I recommend charging them up and letting them sit for a day or so before starting the process. Scrape the positive and negative terminals and with a good soldering iron, you apply heat for less than 3 seconds to attach the tinned leads. In less than 5 minutes you can make yourself a battery pack with over 2x the capacity of a $15 replacement pack for less than $2!

Works fine, too soon to tell about life span.

I have a handful of these and have been using them for years, great price and great use out of them.

We've had 3 Panasonic home phones for many years, the batteries were getting weak, I was able to order the exact number I needed, they were a great price, went from 630mAh to 1000mAh so phones should last longer off charger. Worked great for us!

This is my first time using Tenergy batteries in my electronic devices and I am very happy. They charge up to the rated specification and hold a charge for a very reasonable time period. I will definitely buy Tenergy batteries in the future. Highly recommended.
