ER34615 3.6V 19Ah LS33600 Size D Lithium Button Top Battery

The Batteries were fully charged when I received them, that's a plus, and their longevity will determine the quality of this product. I have installed several of them in a few wireless sensors/Transmitters and they are functioning fine without an issue.

Used these batteries with other components to replicate a proprietary battery pack costing $80. Batteries are not pre-tabbed, so had to figure out how to solder wires onto posts. Soldering iron must be on hottest setting (~450 °F). Use rosin/flux for cleaning and bonding dissimilar metals. Scuff small area on posts, apply flux, then pool small amount of solder being careful to do it quickly so heat does not ruin battery. Allow to cool for a few moments. Tinned wires quickly sink into hardened solder- done.

Thought these were rechargeable. Had to return them.

This part is just what he needed. Thank you.

This long-lasting battery is perfect for wristwatch rotating machines. My last one last over 3 years.
