DUSLAN AA NiMH 800 mAh rechargeable batteries with tabs 12-pack

12-pack AA NiMH 800 mAh with tabs

These twelve rechargeable AA cells deliver 800 mAh at 1.2 volts using nickel metal hydride chemistry. Spot-welded tabs on both ends make them suitable for direct soldering into battery packs or devices that require tabbed connections. They are intended for hobbyists, repair technicians and anyone building custom power packs who needs a tabbed format rather than standard button tops.

Practical limits of NiMH and tabbed terminals

The chemistry exhibits no memory effect and supports recharging up to 1000 cycles, so capacity remains stable through repeated use. Tabbed terminals require soldering equipment or spot-welding gear for secure installation; they cannot be inserted into ordinary spring-loaded battery compartments. The 800 mAh rating replaces lower-capacity cells such as 300, 400, 450, 500, 600 or 700 mAh versions, but runtime will still be limited by the modest capacity compared with higher-rated AA cells.

Build quality and daily implications

Each cell carries spot-welded tabs on both ends, providing a durable mechanical and electrical joint that resists vibration better than pressure contacts. The nickel metal hydride construction offers reliable service life and long-lasting performance across many charge cycles. Because the tabs are permanent, the pack is not suited for devices that need quick battery swaps or standard flat-top AA dimensions; it is built for semi-permanent installation in custom assemblies.
