Do you put your cordless phone back on the charger after every call? I had a phone for several years and it said in the instructions that it was OK to leave it off for a few days before charging so I did and only replaced the battery once. Then the answering maching feature broke so I replaced the phone. Nothing in the instructions about length of time between charges, so I did the same as I was used to. The battery died after a year. I am having quite a time getting a replacement. I got one from Radio Shack, but it won't even hold a charge through a 30 minute call. So I bought another battery today. It's an AT&T battery that is supposed to work in a few different brands. It's charging now so I will try it tomorrow. At $20 a battery, this is expensive. The phone new only cost $40.
