About Rechargeable Power Supplies
All of our dataloggers can be powered by a rechargeable power supply that consists of a rechargeable battery, regulator, and charging source. The charging source powers the system while float-charging the batteries. The batteries then provide back-up power if the charging source is interrupted.
A regulator must be used to connect rechargeable batteries with a charging source. The regulator controls the current flowing to the battery and prevents the battery current from flowing to the charging source.
