OmniCel ER14250 3.6V 1/2AA Lithium Standard Battery Button Top, 4 pack

Great batteries! I use them in my Pyle PTHDL170 USB weather logger at our remote cabin and they work very well. I try to never do a full drain on my batteries to the logger, that way it will always record data without any lapses, so I am not sure of their total life. I usually can get a little more than 4 months out of one of these 1/2AA batteries and I have nearly 4 months on one of these XENO batteries now, so they seem to be high quality with fresh dates. Can't beat the price, these 1/2AA can be expensive in battery stores.

I like the fact that each battery is stamped with the month and year of manufacture. Having the date code on the battery is a nice feature. In my experience, most of these 14250 batteries don't do that. All the batteries tested good when I received them.

Great product

Batteries arrived quickly and work great in our oxygen/heart rate monitor! The longevity of the batteries is still undetermined, but I will post an update on the battery life if it is less than standard (or greater).

When the security system alerts that it's time to replace any of the motion detector batteries every other year or so, we replace them all at the same time. These work great and the price is right.Update 10/22/2021 - a few years later, batteries need to be replaced, purchased a new set.

Bought to replace alarm remote pad battery. Works very well and inexpensive compared to buying from alarm company. I have now bought multiple sets of these and so far I have not had any issues with the batteries that I got. I have bought all of mine from either MYBATTERYSUPPLIER or from BD Supply.Am using these on an older ADT security system -- replacing batteries in both the wireless sensors and the wireless keypads.

Have a hard time finding him here in town and seeing you guys had it so I ordered it they were great. Thanks.

I've tried ordering this brand/model of batteries twice with the same result, DOA. The first batch I didn't get around to using before the 30 day time frame, so I thought maybe it was a fluke. The 2nd batch I checked right away, and the same result all less then 20% life. I then tested them in the device and they lasted a few minutes, no surprise there. I then reached out to the supplier, who claims this shouldn't be (just take a look at the reviews!) They tell me I can get a refund if I ship their junk batteries back to them on my dime! So the bottom line is I would be out the shipping return cost, which is close to the cost of the batteries, just to get my original money back for the junk batteries they sent me. What a scam!These batteries are mailed in a generic little box, not a factory sealed package. They were obviously repacked from another OEM package, they can and should have been tested before shipping out. Save your money and buy somewhere else!
