Maxell 346 SR712SW Coin Cell Battery

Primarily used in watches, the Maxell 346 Coin Cell Battery is a potent power source for its size, holding a charge of 10 mAh and providing 1.55 Volts of current. Thanks to the battery's Silver Oxide chemistry, the 346 possesses a particularly high energy density and discharges at a slow and stable rate, giving it increased longevity compared to other alkaline batteries. The 346 also features Maxell's original leak-resistant processing, which suppresses the electrolytes of the battery from unintentionally leaking out, a fairly common tendency of alkaline electrolytes. In addition to powering watches, the 335 can function in a variety of small electronics including certain calculators, film cameras, medical instruments.

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.
