Practical Operational Examples
Small Handheld Devices
Standard AAA cells are ideal for small remotes. Lookup displays a 10.5 mm diameter and 13 grams weight under NiMH chemistry.
High Capacity Hand Tools
Cordless power tool battery packs historically used Sub C (SC) cells, weighing roughly 52 grams under NiCad chemistry.
Flashlight Cells
Heavy duty outdoor flashlights utilize large D-size battery modules, weighting up to 160 grams under high capacity NiMH formats.
Compact Electronic Layouts
Flat prismatic cells like F3 or F8 are optimized for flat device configurations, displaying slim rectangular thickness profiles.
Formulas & Mathematical Logic
Physical volume estimations of cylindrical cell packages rely on standard cylinder math models.
Package Volume: V = π × (Diameter / 2)^2 × Length
Chemical density: Weight = Volume × Material Packing Density
Because Alkaline, NiCad, and NiMH systems use different core materials and binding elements, their physical density varies, resulting in distinct weights for identical outer package dimensions.

About This Calculator
Compare physical dimensions and chemical weights of all standard battery cells.
The CalcBoy Battery Size & Weight Comparison Tool displays physical and chemical statistics across standard cell form factors.
Selecting the correct battery form factor is crucial for both portable device design and equipment repair. Different applications require specific voltage limits, discharge currents, and weight profiles. Cylinder and prismatic battery formats have standardized sizing standards to guarantee structural and mechanical compatibility.
Battery weight also depends heavily on the internal storage chemistry. Alkaline cells are heavy but standard for consumer devices. Rechargeable Nickel-Cadmium (NiCad) and Nickel-Metal Hydride (NiMH) cells offer higher power capacities, but their chemical formulations result in different weight profiles even for identical package sizes (like AA or AAA).
This interactive tool simplifies the lookup process by letting users filter standard cells, showing diameter, length, and specific chemical weights instantly. It acts as a helpful reference guide for custom battery pack builds, consumer electronics design, and vintage device repair.
Main BenefitProvides quick sizing and weight checks without manual catalog checks.
Formats CoveredSupports consumer cylindrical sizes, sub-C (SC) packages, and slim prismatic cells.
Units DisplayedOutputs physical boundaries in millimeters (mm) and weight metrics in grams (g).
Key DifferenceNiMH cells are generally heavier but offer greater capacity than NiCad cells.
Note: Standard specifications can vary slightly between battery manufacturers depending on terminal cap designs and external casing thickness.

Frequently Asked Questions
1. Why do NiMH and NiCad rechargeable batteries weigh different amounts?
Nickel-Metal Hydride (NiMH) and Nickel-Cadmium (NiCad) utilize different metal compounds in their electrodes. NiMH chemistry uses denser active elements, making them slightly heavier but providing significantly higher capacity than NiCad cells of the same package size.
2. Is there a standard weight for AAA alkaline batteries?
Yes. A standard AAA alkaline cell has a physical package diameter of 10.5 mm, a length of 44.5 mm, and typically weighs exactly 12 grams.
3. What are flat top and button top batteries?
Flat top cells are optimized for building custom spot-welded battery packs, while standard button top batteries have an extended metal tip on the positive terminal to connect securely in consumer battery holders.
4. Why do some cells have '---' listed for alkaline weight?
Many specialty cells (like Sub-C, 4/3 AA, or Prismatic models) are exclusively manufactured as rechargeable Nickel-Cadmium (NiCad) or Nickel-Metal Hydride (NiMH) units. They are not available in disposable alkaline formats.
5. What is a prismatic battery cell?
Prismatic batteries are rectangular, box-shaped cells (e.g. F3, F6, F8). Unlike cylindrical cells, they maximize space usage, making them ideal for flat, compact devices like thin MP3 players and modern smartphones.
6. Can I replace a standard AA battery with a 14500 lithium cell?
No. Although a 14500 lithium cell shares identical physical dimensions with a standard AA cell (14.2 mm x 50 mm), it operates at a much higher voltage (3.7V vs 1.5V) and can damage standard consumer electronics.
