September 17, 201510 yr comment_7941 Sirs, are you able to tell me, if i have my property regularly checked by a fire alarm engineer, do i have to replace the 3.4a 12v fire panel batteries on a routine / aged basis, or are they simply checked regularly until they no longer pass a 'fitness test'? Regards - Nigel Report
September 17, 201510 yr comment_7944 It depends on the brand of the battery and its age. Some brands will last around 5 years some only 3 years. But which ever brand of battery you have they should be tested. If they pass the test there is no need to change them, however if they pass the test but are close to the end of their expected life it would be a good idea to change them. Obviously if they fail the test / show signs of corrosion / other defect they should be changed immediately. Report
