[QUOTE="ProDave, post: 525281, member: 6969"] I have filled in that contact form and await their response. Honestly, dismantling one was an academic exercise to see just what the issue is, and I am far from convinced it is actually premature failure of the batteries but that does not matter. On the subject of alarm life, I get that with ionisation smoke alarms, but have yet to have an explanation of why a heat alarm that just uses a thermistor as it's sensor, should still have the same short life. Thermistors are not well known for failing after 10 years old. Oh and why does a heat alarm, with a much simpler and cheaper sensor than a smoke alarm, cost more? (off subject rant really does not need a reply) Oh and yes if suggesting a replacement, it would be Aico. [/QUOTE]
