DUSLAN 12-Pack Sub C 2200 mAh NiCd Paper Wrapped Batteries with Tabs

Pack Size and Chemistry

This pack contains twelve Sub C nickel-cadmium cells rated at 2200 mAh and 1.2 volts each. They are intended for builders assembling custom packs or repairing cordless tools and emergency lighting that require tabbed terminals. The paper-wrapped sleeves and solder tabs make them suited for permanent installation rather than casual swapping. Buyers expecting a direct replacement for standard alkaline C cells will find these shorter and narrower.

Physical Limits of the Sub C Format

Each cell measures 43 mm long by 22 mm in diameter, so any holder or compartment must accommodate that exact envelope. The paper sleeve offers minimal insulation compared with heat-shrink alternatives, so adjacent cells need careful spacing to avoid shorting through the wrap. Tabs are designed for spot welding or soldering; they are not compatible with spring-loaded battery doors found on consumer devices. The chemistry delivers a nominal 1.2 volts, lower than the 1.5 volts of alkaline primaries.

Cycle Life Determines Suitability

The manufacturer rates the cells for up to 500 recharge cycles under appropriate charge management. That figure defines whether the pack meets the longevity needs of a given application; high-drain or deep-discharge use will reduce the practical count. No built-in protection circuit is present, so the charger or device must handle voltage termination and temperature monitoring. Users needing longer cycle life or maintenance-free chemistry should evaluate nickel-metal hydride or lithium alternatives instead.
