Review: The Fire Alarm Battery - If like me you were fed up of the frequent ‘bleep’ from your fire alarm, then this is more than likely the battery you are going to need. Upon looking inside, this was the type required and whilst it can seem expensive for one battery, it boasts a good battery life and you won’t need to buy another for years to come.
