3.2 Battery Maintenance
It is recommended that the starting battery and ignition batteries be fully charged before starting any
diagnostic work on the generator.
3.2.1 12V 10Ah AGM Starting Battery
This generator comes equipped with 12V, 10Ah, AGM starting battery located behind the
maintenance door. This battery is charged by the generator during periods of frequent usage; if
the battery is not holding a charge refer to (section 4.12). During periods of infrequent use it is
recommended that the battery be charged monthly. A TC2-P plug-in trickle battery charger or
equivalent is recommended. The battery will be damaged by improper charging or overcharging.
If this battery appears swollen or damaged, replace it. Do not replace this battery with one that
has less than 10Ah capacity. It is recommended that the battery be replaced with the exact OEM
replacement battery.
3.2.2 3.6V Li-ion Ignition Batteries
This generator comes equipped with two Panasonic NCR18650B 3.6V Li-ion ignition batteries
which have a 3350mAh capacity and protective circuitry (Fig. 2). They are located in a tray,
mounted on the air cleaner cover. They can be accessed by removing the control panel and
carefully letting it hang from its connections (Fig. 3). These batteries provide power for pre-start
throttle location, and auxiliary ignition power. They are charged while the generator is running.
Inspect them periodically, or as part of a troubleshooting procedure.
Remove the batteries from their tray for inspection; their voltage should be 3.2-4.0V depending
on the temperature.
If the voltage is ≤2.7V, replace both of the Li-ion batteries. If the Li-ion
batteries are not maintaining their charge during frequent generator usage, then check the
charging voltage between the red and black wires of the Li-ion battery connector (Fig. 3) while
the generator is running. The charging voltage can be checked with the batteries in, or out, of the
tray. It should be 3.7-4.2V. If the voltage is within this range but the batteries are not maintaining
their charge, replace the batteries. If the charging voltage is not in this range then test the voltage
regulator refer to (section 4.13).
Check the Li-
ion batteries’ voltage and inspect the terminals monthly during long term storage. If
the voltage ≤2.7V or the terminals are corroded, replace the Li-ion batteries.
This battery must be
replaced with the OEM replacement battery or the exact equivalent (this battery is typically listed
as 3.7V and 3400mAh by most retailers).
