There are two types of 12-volt batteries used in Honda vehicles today: the conventional flooded lead acid (FLA) battery
and the absorbed glass mat (AGM) battery. Each battery type has its own uniquely tuned charging and battery
management systems, therefore cannot be interchanged.
Vehicles with the auto idle stop system come with AGM batteries. If you get one in for an auto idle stop-related issue
such as intermittent operation or a battery low state-of-charge, it's critical that you select AGM for the battery type
setting on the ED-18 battery tester or GR8 battery diagnostic station.
If you happen to select FLOODED (FLA) for testing, this could let a bad battery pass for good, resulting in performance
issues and a possible comeback. Furthermore, if you need to charge that battery with the GR8, serious battery damage
can result if you select FLOODED (FLA).
