Battery Care
Make sure the battery is fully charged before you use the PPP-18i for
the first time. When fully discharged, it takes approximately nine
hours to recharge the battery. Under ordinary operating conditions, the
battery will run your unit with the backlight on for several hours be-
fore it needs recharging. Battery capacity will vary depending on air
temperature, water depth, backlight settings and the size of the sonar
or GPS you are using.
