AA Physics Labs Stackable Series/Parallel Battery Holder

AA Physics Labs Stackable Series/Parallel Battery Holder is an educational modular 1×AA (1.5V) cell holder designed with side interlocking dovetail slots and top screw/banana-clip binding posts for school and college physics electricity laboratories. Multiple holders snap together either end-to-end (in series for 3.0V, 4.5V, 6.0V) or side-by-side (in parallel for increased current capacity), allowing students to visually construct and measure series and parallel battery circuits on the lab bench.

Key Features:

• Interlocking Modular Dovetail Slots: Side and end tongue-and-groove slots allow multiple AA holders to lock together physically into custom series or parallel battery banks.
• Dual Screw / Banana Binding Posts: Equipped with red (+) and black (-) knurled thumb-screw binding posts that accept 4mm banana plugs, alligator clips, spade lugs, or bare hookup wires.
• Clear Polarity & Circuit Visibility: Open-top pedagogical layout lets students trace positive-to-negative current flow and verify Kirchhoff’s and Ohm’s laws directly.
• Heavy-Duty Nickel-Plated Spring Contacts: Holds standard 1.5V AA (LR6) dry cells or 1.2V NiMH AA rechargeable cells firmly with low contact resistance.
• Rugged Classroom ABS Base: Thick impact-resistant plastic base withstands daily handling in school STEM and physics labs.

Technical Specifications:

• Compatible Cell Size: 1 × Standard AA Cell (1.5V Alkaline/Zinc-Carbon or 1.2V NiMH, 14.5mm × 50.5mm)
• Nominal Voltage per Unit: 1.5V DC (Alkaline) / 1.2V DC (NiMH)
• Terminal Type: Knurled Thumb-Screw Binding Posts + Slotted Metal Jumper Strips
• Interconnection Modes: Series ($V_{total} = N times 1.5text{V}$) or Parallel ($I_{total} = N times I_{cell}$)

Mechanical Specifications:

• Base Material: High-Impact Molded ABS Plastic
• Contacts: Nickel-Plated Spring Steel & Brass Binding Posts
• Mounting: Flat Benchtop Base with Interlocking Edge Dovetails

Dimensions:

• Weight: ~22 g

Pinout and Wiring:

• Red Binding Post (+): Positive terminal of the installed AA cell.
• Black Binding Post (-): Negative spring terminal of the installed AA cell.
• Series / Parallel Linking: Use the included slotted metal bridge plate or alligator jumper leads between adjacent binding posts to configure series or parallel connections.

Datasheet Reference:

• Educational Standard: Physics Electricity Lab Modular Cell Holder Apparatus

Commonly Used in:

• School & University Physics Electricity Laboratories
• Ohm’s Law, Kirchhoff’s Law, and Internal Resistance Experiments
• STEM Science Fair Kits and Breadboard Trainers
• Series vs. Parallel Battery Bank Demonstrations

Applications:

• Teaches students how connecting cells in series increases voltage while connecting cells in parallel increases current capacity.
• Provides tool-free thumb-screw terminals for quick hookup to analog voltmeters, ammeters, rheostats, and incandescent test bulbs.
• Eliminates fragile soldered wires that frequently break during classroom lab sessions.
