Durable and reliable over 40 years of service
I have used these batteries as ignition source for model aircraft for over 40 years. They are durable, hold charge for years. I recently dug up a 40 year old Cyclon and it took a charge and held it.

Long lasting if treated well
I have a few marine LED lanterns that after 15 years of daily charge and discharge cycles are still working fine with the original batteries.

Stable and great deep discharge capability. CAUTION. USE EYE PROTECTION AND PREFER USING FEMALE SPADE
Used in some vintage tv battery packs by Sony. In my experience, will tolerate placement of battery tabs, if you use high powered guns sand apply heat for short duration. You must wear eye protection. Will accept standard .250 female insulated spade connectors. Sealed lead acid

Still working!
I got it for a battery replacement for a solar rechargeable LED table lamp and it works better that the batteries that were in the lamp when new. We are now at about 2 years and the battery still works as when we put it in.

They will leak
These batteries will do the job for which they are intended. However I have found in my application that they leak severely after 2-3 years. This could damage sensitive electronic components.
