These lithium coin batteries were used in a dog collar with LED lighting. The original coin cell held only one week, the disappointment was great because the battery change was not intended or written! When a big discounter gave one week deal with the same cell size, and of course have slammed. Laid battery compartment free and exchanged cell also ..hielten only one week (ca.14x half an hour walking the dog).
This contrast Panasonic held at the same condition for 2 weeks, so double as good !!
