Important Compatibility Note:
- Verify that your equipment specifically requires an AA 1.2V nickel-cadmium rechargeable battery before installation.
- DIMENSIONS: The standard AA battery format measures approximately 14.5mm in diameter and 50.5mm in length. Actual dimensions may vary depending on the terminal construction.
- TERMINAL CONFIGURATION: AA NiCd batteries may be manufactured with button-top terminals, flat-top terminals, or factory-attached solder tabs. Confirm the exact terminal style required by your equipment before purchasing.
- Flat-top and tabbed AA NiCd cells are generally intended for compatible battery pack assemblies and should not be assumed to fit standard consumer AA battery compartments.
- NiCd batteries have a nominal voltage of 1.2V, while standard AA alkaline batteries have a nominal voltage of 1.5V. They are not automatically interchangeable in all equipment.
- Do not confuse this 1.2V NiCd battery with 3.2V LiFePO4 or 3.6V/3.7V 14500 lithium-ion batteries. These chemistries are not interchangeable.
- Use a charger specifically designed for NiCd batteries and compatible with the battery's size, capacity, and charging requirements.
- Do not charge this battery using a charger intended exclusively for lithium-ion, LiFePO4, lead-acid, or other incompatible chemistries.
- Some chargers support both NiCd and NiMH batteries, but compatibility must be confirmed in the charger's specifications.
- For a 900mAh battery, a 0.1C charging current corresponds to approximately 90mA. This is a general reference and does not replace the manufacturer's charging instructions.
- Do not use fast charging unless specifically permitted by the battery manufacturer and supported by the charger.
- When replacing cells in an existing battery pack, confirm the original chemistry, voltage, capacity, dimensions, terminal arrangement, and charging system compatibility.
- Do not mix NiCd batteries with NiMH, alkaline, lithium, or other battery chemistries in the same battery pack.
- When using multiple batteries together, use matched cells of the same chemistry, similar capacity, age, and state of charge.
- Always observe the positive (+) and negative (-) polarity markings during installation.
- Do not short-circuit, crush, puncture, disassemble, overheat, or expose the battery to fire.
- Do not use batteries that are leaking, damaged, swollen, or showing signs of excessive heat.
- Nickel-cadmium batteries contain cadmium, a toxic heavy metal, and must be handled and disposed of responsibly.
- Keep batteries away from children and pets.
- Recycle spent NiCd batteries through an approved rechargeable battery recycling program. Do not dispose of them in household trash.
