This set includes four stackable Gridfinity battery holders designed to store AA and AAA batteries. The models come in the following variations:

• 2x2 AA (7U height) – Holds up to 10 AA batteries
• 2x2 AAA (6U height) – Holds up to 10 AAA batteries
• 2x3 AA (7U height) – Holds 14 AA batteries when stacked, or 16 if not stacking
• 2x3 AAA (6U height) – Holds 19 AAA batteries when stacked, or 22 if not stacking

All models are fully stackable and designed to fit the standard Gridfinity system. For the 2x3 variants, a fill limit mark is included—do not exceed this mark if you plan to stack the holders, as overfilling may interfere with smooth feeding when stacked.
