# CR1620 battery

**What replaces a CR1620: DL1620, ECR1620, BR1620, KCR1620, 5009LC**

3 V lithium (primary), 16 × 2 mm (diameter × height)

The CR1620 is a single-use 3 V lithium (primary) coin cell. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** CR1620
- **ANSI / NEDA:** 5009LC
- **Nominal voltage:** 3 V
- **Chemistry:** Lithium (primary)
- **Size:** 16 × 2 mm (diameter × height)
- **Typical capacity:** 81 mAh
- **Rechargeable:** No — never charge it

## Codes that mean the same battery

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

| Code | Fits? |
| --- | --- |
| DL1620 | Yes — same cell |
| ECR1620 | Yes — same cell |
| BR1620 | Yes — same cell |
| KCR1620 | Yes — same cell |
| 5009LC | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| CR1632 | Same 16 mm diameter, 3.2 mm tall. Nearly twice the capacity and too thick for a CR1620 slot. |
| CR2016 | The digits are easy to transpose. CR2016 is 20 mm across and 1.6 mm thick — a different cell entirely. |

> The CR1620 is a primary cell and must never be put in a charger. Charging a sealed primary battery builds gas pressure inside a can with no vent designed for it, which is how they rupture or catch fire. Rechargeable look-alikes exist for several sizes and carry different codes — check the code, not the shape.

## Where it turns up

- Car key fobs, notably Nissan, Mazda and Subaru
- Tyre pressure monitoring sensors
- Heart rate monitor chest straps
- Small digital calipers

## Common questions

### What is equivalent to a CR1620?

DL1620, ECR1620, BR1620, KCR1620, 5009LC — all the same 3 V cell under different manufacturer codes.

### Can I use a CR1632 instead of a CR1620?

Same 16 mm diameter, 3.2 mm tall. Nearly twice the capacity and too thick for a CR1620 slot.

### Is the CR1620 rechargeable?

No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
