Last night I hear a noise like a sharp crack from the kitchen. Then my 2nd CO2 alarm beeped indicating battery change required.
The 9V Asda battery was due to expire Dec 2016. But 3/4 of the top (with the silver parts)which affixes to the device was cracked open. I was anxious but could see no white bits nor fluid. It seemed dry. I wrapped it up & reinspected it this morning - no change. Scellotaped battery up & disposed of it responsibily. The device recommended using Duracell battery - did the battery crack because it was a supermarket one or has this happened to anyone else. I get nervous with dodgy batteries. Any ideas/advice. Thanks
