Cell types in this size
SR716SW
Low drain (SW): for plain analog watches · Silver Oxide2
12 codes in our sources name this cell type.
LR716
Alkaline cell of the same size: the IEC digits are the size, the L is the chemistry. LR716 lands on this page by that rule; our sources hold no alkaline datasheet for it, so no figures are shown.

Can I use another cell instead of 315?
Verdicts follow our swap rules from the datasheet size, voltage and cell type.
Use instead of SR716SW
LR716
Fits, with a catchFits, but LR716 is alkaline and runs shorter.
Same 7.9 mm × 1.65 mm size. LR716 is an alkaline (L) cell; the watch is made for silver oxide (S). Use it to get the watch going, then fit SR716SW.
Draw both cells in the swap checkerNo: SR714SW is 0.2 mm thinner than SR716SW.
Same 7.9 mm diameter, but SR714SW is 1.45 mm against 1.65 mm: the contact spring may not reach it.
SR714SW: 7.9 mm1 × 1.45 mm1, 1.55 V1
Draw both cells in the swap checkerNo: SR721SW is 0.45 mm taller than SR716SW.
Same 7.9 mm diameter, but SR721SW stands 2.1 mm against 1.65 mm: the case back presses on it or does not close.
SR721SW: 7.9 mm1 × 2.1 mm1, 1.55 V1

Questions
What is the 315 battery equivalent?
SR716SW, V315, B-315L, 614, 280-56, 9937, 080-D54, SB-AT, SR716, SR67 name the same 7.9 × 1.65 mm silver oxide cell as 315. Any maker's cell under one of these codes fits.
Is 341 the same as 315?
No. SR714SW is 0.2 mm thinner than SR716SW. Same 7.9 mm diameter, but SR714SW is 1.45 mm against 1.65 mm: the contact spring may not reach it.
Is LR716 the same as SR716SW?
No: LR716 is an alkaline cell of the same size, SR716SW is silver oxide. Fits, but LR716 is alkaline and runs shorter. Same 7.9 mm × 1.65 mm size. LR716 is an alkaline (L) cell; the watch is made for silver oxide (S). Use it to get the watch going, then fit SR716SW.
What watches use the 315 battery?
In our base: 27 Seiko calibres (5E20, 5E21, 5E29, 5E30…). The full lists are on this page, with the brand tables they come from.
How long does a 315 battery last in a watch?
Seiko's battery chart gives 2 to 3 years for its 27 calibres on this cell, 3 years most often. Life depends on the calibre's current draw, not on the cell alone.
