Maxell 315 Watch Battery - 5 Pack

Mercury-Free Formula

The Maxell 315 watch battery is part of the company's SR collection of silver oxide button-type batteries. This particular button cell battery, also known as the SR716SW, is designed to power low-drain electronics.

We recommend using this non-rechargeable battery within your analog watch or calculator. The Maxell 315 features a silver oxide chemistry, which provides a stable discharge current that won't vary in voltage.


In fact, the flat discharge rate of a silver oxide battery is designed to provide the same voltage level until the end of the battery's life. Alkaline batteries, on the other hand, offer a more slopped discharge characteristic that lowers the voltage over time, therefore lowering your electronics' performance as well.

This is why it is important to replace silver oxide button cell with batteries of the same chemistry so that your devices' maintain optimal efficiency.

Maxell is a leading manufacturer of specialty button cell batteries industry, including the 315 watch battery. These non-rechargeable batteries offer a stable operating voltage in a safe package that won't leak or damage your devices.

In addition to being safe and reliable, Maxell button cell batteries are free of mercury and therefore have less of a detrimental impact on the environment. Please note that the Maxell 315 watch battery is sold by the piece; however, the button cells are packaged in tear strips of five units. 

The Maxell 315 watch battery is the solid choice for powering your low-drain, personal electronics.

I have been using this pump all summer to keep my boat, lawn tractor and a whole bunch of other stuff filled up around here. I still use 5 gallon containers for their portability and even with 10 of those I'll have to fill them twice to get through the summer. This pump has been great for my needs. If you are sick and tired of having to hold a 5 gallon container of fuel in the air while attempting to get those funky nozzles to work, buy this pump.


I have two of these and found them really useful. No more spillled gas and pumps fast!

So far it’s working as well as I had hoped. Nothing is perfect when trying to transfer gas, but this does a very decent job. You need to make sure to lift the nozzle and hose up at the end of the fuel transfer to allow any residual fuel to run back into the tank or it will dribble out all over. It empties most of a five gallon gas can in a couple minutes without having to lift and hold the can up which is exactly what I wanted.
