DUSLAN 1/2 D NiMH Flat Top Battery 3500 mAh

Purpose-built cell

This 1/2 D NiMH flat-top battery delivers 3500 mAh at 1.2 volts for devices that require this specific form factor. It suits equipment manufacturers, maintenance technicians and hobbyists who need a direct replacement for legacy 1/2 D compartments. The flat terminals on both ends ensure a solid mechanical and electrical connection without solder tabs. Buyers who need a larger D cell or a smaller sub-C size should select the matching chemistry instead.

Thermal and electrical behaviour

Nickel-metal-hydride chemistry exhibits minimal self-heating during typical charge and discharge cycles, so the cell remains close to ambient temperature in normal use. No audible noise is produced because there are no moving parts or forced-air cooling. Internal resistance stays low across the 1000-cycle rated lifespan, keeping voltage sag modest under moderate loads. The 82 gram mass and compact 35 mm by 32 mm profile add negligible thermal mass to the host device.

Ready-to-use benefits

The pack arrives pre-charged and free of memory effect, so it can be topped up at any state of charge without capacity penalty. Flat-top terminals allow immediate insertion into spring-loaded holders or battery trays, eliminating the need for spot-welding or adapter sleeves. Rated cycle life of 1000 recharges reduces replacement frequency in high-duty applications such as emergency lighting, portable instrumentation or RC transmitter packs. No charger or software is bundled, so users select a compatible NiMH charger that matches their workflow.
