High-capacity D-size NiMH cell with solder tabs delivers 10000 mAh at 1.2 V and up to 1000 recharge cycles
This D-size nickel-metal hydride battery delivers 10000 mAh at 1.2 V and is built for devices that draw steady current over long periods. The chemistry avoids memory effect so partial recharges do not reduce usable capacity. Tabs on both ends allow direct soldering or spot-welding into custom packs. Rated for up to 1000 recharge cycles under normal use.
Unlike high-rate cells that sag quickly, this pack maintains stable voltage through extended runtime in portable lighting, medical instruments or backup modules. The 161 g mass and 59 mm by 32 mm cylindrical form factor store enough active material to support multi-hour operation without voltage collapse. Low self-discharge keeps the cell ready after weeks in storage.
Soldering directly to the tabs requires a temperature-controlled iron and flux to avoid overheating the seal; excessive heat is the most common cause of early failure. Spot-welding is preferred for production builds. Polarity is marked on the wrapper — reversing it damages the cell and the load. No charger is included; use a NiMH-specific charger matched to the 1.2 V chemistry.

No published specifications for this item yet.
NiMH chemistry generates modest heat under load; the 161 g mass helps absorb it, so the cell remains warm rather than hot during extended discharge.
The 59 mm length and 32 mm diameter require a D-size battery holder with spring or solder-tab contacts that accept flat terminals on each end.
Yes — most D-cell devices tolerate the lower 1.2 V nominal voltage, though runtime per charge may differ from alkaline equivalents.
