Initial Charging of the Battery CellsTo charge the Magmeter-2 batteries, connect the mains charger and switch on the mains supply(if appropriate). The charging LED (item 8, Front Panel Controls) will begin to flash indicatingthat “fast charging” is taking place. Once the fast charge cycle has completed, the LED will stopflashing and be lit (ON) continuously, to indicate that “trickle charging” is continuing.Note: When battery cells are inserted for the first time, they should be continuouslycharged for 16 hours to ensure full capacity.Note: The Magmeter-2 can be used whilst charging the battery cells or used directly frommains power without any battery cells being installed. However, the outputs may carrysome charger noise.Note: If the Magmeter-2 is powered by the mains charger with no battery cells installed,the charging LED may flash. This is normal and can be ignored.Note: To prepare for long periods away from a charging source, battery cells may be pre-charged and used to replace discharged cells in the field.Note: Battery capacity will decrease over time, depending on age and use.6.3.
