SO... after more years than I can remember (maybe never??), had to buy new batteries for Panasonic cordless base unit phone plus 2 more handsets. That means SIX.
Of COURSE they only come in packs of FOUR... so now am sitting with two useless batteries that will probably outlive me/ any use for them.🤣 IF anyone is the same boat of four not being enough, happy to sell you two since 4 (Steren) were $140 pesos
