Using electric storage batteries safely
Health and Safety Executive Most batteries produce quite low voltages, and so there is little risk of electric shock. However, some large batteries produce more than 120 volts DC. To protect people from the real danger of electric shock,1 you should: Ensure that live conductors are effectively insulated or protected.
Electromotive Force: Terminal Voltage
The voltage across the terminals of a battery, for example, is less than the emf when the battery supplies current, and it declines further as the battery is depleted or loaded down. However, if the device''s output voltage can be measured without drawing current, then output voltage will equal emf (even for a very depleted battery).

How to make a simple negative power supply
Another solution would be to use an isolated DC-DC converter - connect its positive output to the negative terminal of your main supply, then its negative terminal is your negative supply. Some DC-DC converters are not isolated (their input and output ground terminals are connected) so cannot be used here.

How a battery works
When we connect an almost flat battery to an external electricity source, and send energy back in to the battery, it reverses the chemical reaction that occurred during discharge. This sends the positive ions released from the anode into the electrolyte back to the anode, and the electrons that the cathode took in also back to the anode.
