CO detector choices.

Is there anything wrong with using a AA battery operated CO detector from Wally World verses one that came hardwired in my RV? The manual for the new unit said nothing about not using it in a MH. It has a low battery warning and the batteries are meant to last two years. It's not drawing down the coach batteries and it's 1/3 the price of the OEM unit, which may not be available, anyway.

What say you experts?

TIA,
Eric

    No.
    I called one of the companies that make the battery operated models and they said the only reason they don't recommend it's use in a RV is because they had not tested it in one.
    So I've been using one (two really, the first one got old) for the last ten years and it has been fine.

    Supposedly the ones rated for RV use are more rugged and can handle more extreme temperatures than the house units. When our original alarm crapped out I bought a house unit from Wally World. It failed after one season. I got an RV rated unit from Amazon and it has lasted three seasons so far. As always, YMMV...

    No different than using a battery operated Smoke Alarm.

    Keep it clean, check batteries twice a year
