Can I use another cell instead of CR1616?

Verdicts follow our swap rules from the datasheet size, voltage and cell type.

Check any other pair

  • Use instead of CR1616

    CR1620

    No

    No: CR1620 is 0.4 mm taller than CR1616.

    Same 16 mm diameter, but CR1620 stands 2 mm against 1.6 mm: the case back presses on it or does not close.

    CR1620: 16 mm3 × 2 mm3, 3 V3

  • Use instead of CR1616

    CTL1616F

    No

    No: CTL1616F is a rechargeable cell.

    CR1616 is a primary lithium battery, 3 V. CTL1616F is cobalt-titanium rechargeable, 2.3 V; a battery-powered watch has no circuit to charge it.

    CTL1616F: 16 mm4 × 1.7 mm4, 2.3 V4

Warnings from the makers

Keep away from children

“(1) KEEP OUT OF REACH OF CHILDREN. Swallowing may lead to”[1]
“serious injury or death in as little as 2 hours due to chemical burns and”[1]
“Keep batteries out of reach of small children. Should a child swallow a battery, consult a physician immediately.”[7]

Questions

Is CR1620 the same as CR1616?

No. CR1620 is 0.4 mm taller than CR1616. Same 16 mm diameter, but CR1620 stands 2 mm against 1.6 mm: the case back presses on it or does not close.

What watches use the CR1616 battery?

In our base: 3 Seiko calibres (A944, G300, W710…); 4 Casio models. The full lists are on this page, with the brand tables they come from.

How long does a CR1616 battery last in a watch?

Seiko's battery chart gives 2 to 7 years for its 3 calibres on this cell, 7 years most often. Life depends on the calibre's current draw, not on the cell alone.
