Can I use a rechargeable 9V battery in a Divesoft analyzer?
A rechargeable 9V battery can power the analyzer but will not charge in the 9V compartment; version 4 supports a separate internal Li-ion battery option.
Yes, it is, but it will not be recharged, 9V supply is for primary cell only. Starting with version 4, the analyzer is prepared to use LiIon rechargeable cell, but it has to be installed inside the device. This built-in battery can be recharged using external power supply or USB cable. The battery kit is not available yet at this moment, please check our News section on main page.
