# Pouch cell (no size designation) battery

**What replaces a Pouch cell (no size designation): Li-poly, Li-Po, lithium polymer, pouch cell, LiPo**

3.7 V lithium-ion (rechargeable)

The Pouch cell (no size designation) is a rechargeable 3.7 V lithium-ion (rechargeable) pack. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** Pouch cell (no size designation)
- **Nominal voltage:** 3.7 V
- **Chemistry:** Lithium-ion (rechargeable)
- **Rechargeable:** Yes

## Codes that mean the same battery

*Different manufacturers, one physical battery. Voltage, chemistry and dimensions all match.*

| Code | Fits? |
| --- | --- |
| Li-poly | Yes — same cell |
| Li-Po | Yes — same cell |
| lithium polymer | Yes — same cell |
| pouch cell | Yes — same cell |
| LiPo | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| Any cylindrical Li-ion | A pouch cell has no standard size at all — the dimension code on the label, such as 603048, is simply thickness, width and length in tenths of a millimetre and millimetres. Two cells with different codes are different cells, and a pouch has no metal can to contain a failure. |
| NiMH packs | Same connector styles are sold for both. A NiMH charger applied to a LiPo will overcharge it, and an overcharged LiPo swells and can ignite. |

## Where it turns up

- Phones, tablets and laptops
- Bluetooth earbuds and their cases
- Drones and RC models
- Smartwatches and fitness bands

> The chemistry is lithium-ion; "polymer" describes the gelled electrolyte and the soft foil pouch, not a different cell reaction. 3.7 V nominal, 4.2 V charged, and a hard floor around 3.0 V. A swollen pouch is a failed cell — stop charging it, do not puncture it, and dispose of it at a battery collection point rather than in household waste.

## Common questions

### What is equivalent to a Pouch cell (no size designation)?

Li-poly, Li-Po, lithium polymer, pouch cell, LiPo — all the same 3.7 V cell under different manufacturer codes.

### Can I use a Any cylindrical Li-ion instead of a Pouch cell (no size designation)?

A pouch cell has no standard size at all — the dimension code on the label, such as 603048, is simply thickness, width and length in tenths of a millimetre and millimetres. Two cells with different codes are different cells, and a pouch has no metal can to contain a failure.

### Is the Pouch cell (no size designation) rechargeable?

Yes. Use a charger made for its chemistry and never substitute a primary cell of the same size.
