I ordered the Tenergy Propel Sub C 3000mAh NiMH Flat Top Rechargeable Battery (with/ Tabs) 10516-1 on Dec.17,2020. They arrived Dec. 22. I bought them to replace the 5 Ni-cads in my old Black & Decker drill/screw driver model 9020 type 4. Soldered them into a pack and they work great and charge just fine with the original charger.
