Many standard Surface Pens use one replaceable AAAA alkaline cell for inking, but the Surface Slim Pen and Slim Pen 2 have internal rechargeable batteries and must not be opened for a AAAA replacement. Some older cap-button designs also use separate 319 coin cells for Bluetooth functions; those are not AAAA cells. Confirm the pen model first, then buy a sealed 1.5V AAAA/LR61 cell or pack from a reputable source.

Buying tips
- Microsoft identifies several regular, clip and classroom/business pens as AAAA-replaceable, while Slim Pen and Slim Pen 2 are rechargeable and have no replaceable AAAA cell.
- Install a fresh AAAA with the positive end toward the pen’s tail as Microsoft specifies, and do not try to recharge an alkaline AAAA cell.
- A Surface Pen with an older Bluetooth cap may separately use 319 coin cells; replace only the battery type specified for that function.
