So what makes you think you need to replace a smoke detector every 5
years? I had units in my house that lasted over 20 years.

On the other hand, I have not seen a CO2 detector for near the price of
a smoke detector. Are they really so inexpensive?

But that is what the chap claimed, the sulfating is what is killing
these deep cycles very early. And I will follow your advice very much, I
will never allow
these batteries to fully discharge or to not be topped up monthly. I
will top them up monthly. I always have paid close attention to my
batteries when in storage for winter season, now I will pay closer
attention.

Interesting the chap there at C.T. told me that the new battery will not
desulfate.

Interesting enough also that when I put the two batteries side by side
and the new advanced ultra model was actually the same weight yet
smaller in size.

Just like any other industry, especially marine, they will not make me a
battery to last a lifetime, they need me to replace my batteries
regularly. Their accounting and marketing departments bank on it. Same
as the smoke detectors in the home, our firedepartment is going door to
door in my neighborhood inspecting and if you do not have they will sell
you for $45.00 one for each floor (also a carbon monoxide detector) for
same price, yet if you check ebay they are only $8.00 . But I am sure
smoke detectors and CO2 detectors can last longer than 5 years and
function properly, but if they lasted a lifetime or the lifetime of the
house, the smoke/CO2 detector businesses would hurt. So industry leaders
bribe political leaders and so goes a nanny state.

O well,,

Thanks a lot for all the advice, much appreciated
