    9 volt lithium battery load or capacity tester?

    Is there a simple yet accurate capacity or load tester (i.e. ZTS MTB-1) that will test lithium 9 volt batteries? None of the ZTS models seem to be able to do so. Thanks

    Short lived Duracell AAA non rechargable?

    I have a vacation home with a home automation system that relies heavily upon battery operated devices. All of my door and window sensors use AAA batteries. I started off using alkaline but they were running down after 3-4 months in some of the more heavily utilized devices. I tried switching...

    Rechargeable Battery Questions - non flashlight

    I finally made it to my house in HI. The battery testing results of the batteries stored in my very warm garage with the MBT-1 were surprising. The better brands of alkali, like duracell, tested at 100%. A cheaper brand (GP alkaline) of unused AAA batteries that came with the sensors all tested...

    Why do lithium batts last 2 times longer in one device, but 5-10 longer in another?

    Can you be a little more explicit on how to determine current draw? I understand that if I have a battery with a known capacity (x mah) and it runs for 10 h before dying, my current draw would be x/10 ma. However, in reality I don't know the capacity of my battery at the onset and I don't know...

    My MBT-1 arrived and I tested 3 lithium CR2 batteries from 2 door sensors that I plan to relocate in my other home and 1 from a sensor that I haven't installed yet. The 2 used CR2's tested at 20% while the new CR2 tested at 100%. These batteries don't have a brand label and came with the...

    Rechargeable Battery Questions - non flashlight

    I have just bought a supply of energizer ultimate AA & AAA batteries online as well as a zts mbt-1 tester. I was planning on tossing the batteries stored in my hot garage but now I will test them first. I also plan to test the batteries stored in my cooler lower level closet to see if that makes...

    Rechargeable Battery Questions - non flashlight

    I appreciate all of the advice given so far. Since I first posted I read about the effect of heat (80-90F normal indoor temperature in HI) on batteries and perhaps that is why they are dying so quickly even before I buy them in some cases. I think the reason that some of these batteries were...

    Rechargeable Battery Questions - non flashlight

    I have 12 battery operated door/window sensors (3 AAA each), and 4 battery operated push button door locks (4 AA each) which eat batteries fairly quickly (1-3 mo). Compounding that problem are the battery life that I get when I quiry them remotely is unhelpful. Typically, the battery lifes look...

    Best CR2 battery for zwave door/window sensor?

    I have a number of door/window zwave sensors installed that drain batteries within months. One type that I use has a CR2 battery. Should I pay the premium for a good lithium battery such as the energizer e2 or would most lithium batteries suffice? I am looking for the longest battery life. I am...
