BetaGauge 330 – Rechargeable Battery Pack

Wow! It’s one new thing after another…

Most of our calibrators use replaceable and convenient Alkaline batteries either AA or 9V types. They’re readily available in all markets. But, for reasons of economy or ecology, some people prefer rechargeable batteries. We’ve sold these as an option for everything we make.

Now, we have a new purpose designed and made battery pack for the BetaGauge 330 Pressure Calibrator. Because of its built-in electric pump, the 330 uses (8) AA cells. Previously, to use rechargeable batteries, you had to take out all 8 cells, put them in one or more chargers and then reinstall them. That’s a bit user unfriendly. Being the smart and friendly people we are, we decided to create a sealed battery pack with external charger to make this quick and easy.

Our new battery pack also offers a bit better performance with a total of 2.7 Ah available energy against 2.0 Ah from the Alkaline cells. Since the Nickel Metal Hydride (NiMH) batteries have a lower internal resistance than Alkalines, they are able to squeeze more out of each charge, too.

A fully depleted pack can be recharged in about 2 hours and can be expected to provide up to 400 complete pump cycles from 0 to 150 PSI.

The charger is a universal type (100-240 VAC, 50/60 Hz input) that comes with a set of snap in adapters for use with any type of mains connection outlet.
