Batteries as Shipped
Your PSA-37XP includes one Li-Ion battery pack, with the option of one additional battery packs.
These battery packs have been installed in the rear battery chamber, but have been unplugged for
shipping. Upon receipt of your PSA-37XP, please remove the rear battery chamber cover and plug in
each battery pack.
Charging
A single battery pack will charge in approximately 2 hours per cell with the power of the PSA -37XP off
but plugged in, and 4 hours per cell with the power on. When you first receive the PSA -37XP, the bat-
teries should arrive partially charged. These batteries do not have the “memory” problems that inferior
batteries have, and do not need to be charged fully before use, and do not need to be fully discharged
before a recharge cycle. In other words, use them, and forget they are there helping you get the job
done.
