Well, at least they are used "in" the home.
I've had mixed results with these. Some cells last a long time. Others go dead faster. For example, the amplified speaker for my PC, I just changed the batteries. Two were stone cold dead, two were well charged.
The one email I got from them, the fellow wrote that if they dropped below 1.1 volts, the cell would be damaged. So, the two ones which came out dead, are likely damaged.
I'm thinking that it would be wise to charge them on schedule (every week?) rather than waiting for them to go dead. Has anyone else got experience with these batteries?
