I've replaced all the backup batteries in the smoke alarms in the house. The system runs off the mains to the 9v batteries are just there in case of a power cut and they're good for a couple of years yet and I've used as many as I can in my active basses. If you want a pack of 2 PM me and I'll give the first two to get in touch my address, just post me a stamped addressed envelope and I'll post them off to you.
