Lithium cell 4T32 Yellow

Description There is a known family of M4T32 Snaphat lithium battery modules (used for RTC, memory backup) by STMicroelectronics. It’s possible “4T32” is a truncated version of that. I did not find a product listing via standard battery suppliers under “4T32 battery yellow” in product searches. “Electropoint” appears in one source (a document called 4 6 2 1 — Electropoint Distribution SA) in the context of a catalog of components. In that “Electropoint Distribution” catalog, there is a mention of Battery and different color codings (e.g. “Yellow, White, Blue, Green”) under “Battery / Charging” in the table of contents. That implies that Electropoint’s catalog classifies some battery items by color. Thus, “4T32 yellow” could be the “yellow” variant (color-coded) of a “4T32” series item in the Electropoint battery catalog. What “4T32 yellow” might mean (hypothesis) Putting together the clues, here is a possible interpretation: 4T32 is a series or model designation for a small lithium backup battery cell / module. Yellow identifies a variant in that series (maybe the wrapper color, or a color code used by the distributor Electropoint to distinguish voltage, capacity, or chemistry). In the Electropoint catalog, under “Battery / Charging,” they list colors (Yellow, White, Blue, Green) which may correspond to different battery types or categories. So “4T32 (yellow)” might mean: the 4T32 battery, with the yellow-coded variant in that catalog. If it is indeed aligned with the M4T32 Snaphat family or similar, typical specs might include: Spec Approx / Typical Chemistry Lithium (likely small cell for backup) Operating temperature -40 °C to 85 °C (common for RTC backup batteries) Mounting / packaging Snaphat / snap-on style module (so that it is mounted after soldering) Capacity Something like ~120 mAh (for M4T32 in known lines) But these are guesses based on similar known items; they may not exactly match the “4T32 yellow” you have. If you like, I can try to find the exact datasheet for “4T32 yellow Electropoint” using more details (markings, dimensions, context). Would you like me to try that next? If possible, send me any extra markings or the physical dimensions of the battery.
