This 391 (SR1120W) is a popular silver-oxide cell that is typically found in watches. It is high drain and suitable for power hungry devices such as watches with backlights and alarms.
The low drain equivalent of this (SR1120W) cell, the 381, can happily be substituted by the high drain 391.
Four of these 391 (SR1120W) cells are used in Volvo remote control keyfobs. For example the key fob T1215 remote used in the Volvo 850 and the Volvo 940.
These (SR1120W) cells have a shelf life of 5 + years, so why not buy two or more. Take advantage of our reduced price and make sure you are not left without a watch next time your battery runs out.
