Synergy Digital Cordless Phone Battery for Panasonic HHR55AAABU Phone, Ni-MH 1.2V 1000mAh - Ultra High-Capacity Battery Review

The Panasonic HHR55AAABU cordless phone battery is not worth the money. Based on my observations, the battery drains too quickly, barely lasting through a full day of moderate use. It also seems to have a shorter lifespan than other batteries I've used in the past.

After a Christmas present and opening I found this is NOT the item described. Instead of 1.2 volts it was 1.25 volts and it was NOT working in my phone. However, the return window has closed leaving me stuck with batteries I can't use. Lesson Learned: Don't Trust East Coast Photo's Product Description!

These are identical (virtually improved) to the rechargeable batteries in my Panasonic handheld phone. When they failed after a few years (I left my phone without a charge for over a month and the old ones didn't charge well), I wanted to make sure the replacement was good quality and couldn't catch fire or otherwise damage my phone . I bought it and am very happy with it.
