Review on 💾 Enhance Performance & Preserve Data with Powerbuilt 648539 Computer Memory Keeper by Brandon Havlicek

Didn't work for me. I have read the instructions as well as most of the comments on Revain on how to do it properly. I used a brand new 9v battery and made sure the keys are turned to accessory mode and anything that can draw current is off. So that the actual battery change takes as little time as possible, I even removed the anchors from the battery beforehand. In general, replacing the old battery with a new one took less than 3 minutes. When I was done, I took a deep breath, turned on the radio, and cursed loudly as the radio's LCD read "CODE." $5.99 spent for next day shipping.
