10 Pack for Saft LS14250 1/2AA 3.6v Battery 14250 Can Use for Dogwatch R9 Leash 1200mAh High Capacity

These batteries are great, we use them for machines at our shop with 60-80 hours off spin time per week and they last about 2-3 months. Great choice for needed batteries.

Great price for the style you get. Probably knock offset but hard to pass up the price.

I have a few devices that require the 14250 sized batteries and I have found that these Saft LS14250 batteries are perfect for the job. I prefer the Li-SOCI2 chemistry over the Li-Ion formulation due to its superior temperature handling and the stability. There is no fire hazard with these and they don't need special labeling or handling like Li-Ion. They last a long time (they have a higher energy density as well).One caution. Do not try to use 2 of these batteries in place of a 14500 battery as each of these batteries has a nominal voltage of 3.6V and putting 2 in series boosts the voltage to 7.2V and could do serious damage to the device you are powering.

I ordered a ten pack. Only 2 of the 10 batteries were any good. I've purchased this brand before and don't recall having this problem (maybe just one). But this was ridiculous.

The batteries were defective because it didn't power on the device.

The whole package I ordered was broken by the time I used it. I think they are useful at first. Borrowed some of the same brand of products, the effect is not bad. Choose different sellers. Batteries of the same brand have been good in the past.
