    These are worth the money, August 11, 2012

    HereInCA “RetInCA” (California) –

    These batteries are a tight fit for some uses, but they were intended to be used in smoke detectors where they fit just fine. The expiration date is not a fixed “drop dead” date for those of you that complained about an 8 year expiration. Also, these are not made or intended to be recharged as one person complained they only got two recharges out of them – and last, to the tech guy who tried to solder the contacts – then complained the contact plate was plastic – what did you have in mind: metal? The contacts are soldered from the bottom – you probabaly unsoldered them when you soldered your wires to them. Gold clips would have worked just as well for any audio application. I am puzzled that a person would give 4 stars because of the perception that the battery lasts longer.

    I’ve used these in smoke detectors that wore alkaline batteries out in a year and these lasted 12 years. I have 10 smoke detectors and they all have these batteries. I’m buying more now to prevent a worn out battery from failing when I need it – but i think 12 years was very fair for the price. People – don’t ruin it for others with negative reviews because the battery didn’t work as it was never intended. I might have passed on these if I hadn’t already used them – because of what some of you wrote. Be fair.

    I posted this on another packaging, but there seems to be a lack of understanding on battery life.
    The shelf life of this battery is rated at 10 years. The shelf life of a standard alkaline is rated at 5 years. So it’s twice a long lived if you don’t draw any current.
    The mah capacity of this device (at low current drain) is 750. For the alkaline, 600. So it lasts just a little longer in use.

    There are 2 types of smoke detectors. One is wired into the house, and only uses the battery for backup when the power is off. For this application, the lithium should last about twice as long. Well worth the trouble of getting out a ladder.
    The other kind of detector runs off of the battery. This is the detector you added to a room without doing any wiring. For this case, you might as well use a alkaline. It’s going to last about the same.
    This is a great battery for backup applications. Especially where hard to get to. Don’t confuse loaded and unloaded life.

    Fits in the smoke alarm, March 11, 2012

    Others commented that the battery seemed too large to fit in some items. It fit into the 3 different smoke alarms we have in the house without difficulty. Still all working after 3 years.
