fnb-58li and fnb-80li battery screw

Karin Johnson #25 Hello Group: Does anyone know what type of screw on the outside of the fnb-58li or fnb-80li battery is called??? What type of tool can be used to open the battery case? I recently obtained a replacement battery for my HT, and would like to experiment with replacing the Lithium cells in the old case. Karin Anne Johnson? K3UU Palm Harbor, FL

Clyde Lambert All Messages By This Member #100 There are No screws holding the case together. The three contacts that appear to be screws are not holding the case. They are battery charge contacts only. The case halves are bonded together by either glue or ultrasonic welding. I use either a x-acto knife or scalpo to cut the seams apart. I have also used a "hot knife" but desided the x-acto or scalpo worked best. Easier to control. After replacing the batteries, I use a UV cured bonding agent to reassemble the case. You have to take your time when separating the case. That is if you want a usable battery pack after you're done. Above all, do not rush the project, it will take some time to do a proper job. Anyway, good luck and ha e fun. Clyde KC7BJE Retired Electronics Manufacturing Engineer ?
Tobias KK7BCO/2M0TFF All Messages By This Member #101 Thank you very much! excellent documentation.I had no idea these packs used round cells. I have been doing ok with an Amazon or eBay battery, and using the original old battery as backup for now. toggle quoted message Show quoted text On Fri, 4 Oct 2024 at 20:20, Clyde Lambert via <clyde.lambert=[email protected]> wrote: There are No screws holding the case together.
