Twenty-four tabbed AA NiMH cells deliver 1.2 V and 1800 mAh each for up to 1000 recharge cycles
These 24 AA nickel-metal-hydride cells each store 1800 mAh at 1.2 Volt and arrive with solder tabs on both ends. They suit hobbyists and technicians who build custom packs for RC models, emergency lighting, medical devices or DIY electronics projects. The chemistry avoids memory effect so partial recharges do not reduce usable capacity.
Every cell measures 49 mm long by 14 mm in diameter and weighs 29 grams. The welded tabs replace the usual button tops, allowing direct series or parallel connections without extra holders or spring contacts. This tabbed format saves space inside tight enclosures and speeds up pack assembly on the bench.
The manufacturer rates the cells for up to 1000 recharge cycles when charged and discharged within normal current limits. In sustained service the tabs conduct current without the resistance spikes that loose contacts can develop, so voltage sag stays predictable over many months of daily cycling.

Each cell has tabs on both ends rated at 1.2 Volt and 1800 mAh; apply a temperature-controlled iron briefly to avoid overheating the 49 mm by 14 mm Nickel Metal Hydride cell, which can damage the separator and reduce the 1000-cycle rating.
The manufacturer specifies up to 1000 recharge cycles; with daily charging this reaches the limit in roughly three years, so schedule a refresh when capacity drops below 80 % of the original 1800 mAh rating.
Internal resistance in the Nickel Metal Hydride chemistry causes voltage to sag under sustained loads, so the 1.2 Volt output drops toward the device cut-off threshold before the 1800 mAh capacity is fully delivered.
