QBLPOWER BT18433 BT28433 BT184342 BT284342 BT-1011 Cordless Phone Battery Compatible with AT&T Vtech CL80109 CS6209 TL90078 BT-8300 BATT-6010 Uniden BT-1018 BT-1022 CS6219 (8 Pack BT18433 Batteries)

Well... Purchased these a year ago, for which each and everyone of the has failed. At first they were great replacements. Shortly thereafter, though the standby time (per the phone battery indicator) was holding, their usage time began to drop-off (decrease). Finally, they began to exhibit an inability to fully charge. At their final stage, they indicate being half charged, at best, and immediately when the phone is answered they would fail. The original batteries had lasted 4 to 5 years. Go figure?

Got these for our Uniden cordless phones - we have the set with a master and 3 satellites. They fit well, come partially charged so you don't have to worry about your phone being dead while the new battery charges. And you certainly can't beat the price.
