Battery Types
After changing the battery, a screen will prompt for the battery type
to be entered�
The Petrel attempts to guess what type of battery is being used� If
the battery type is incorrect, it should be manually edited�
Having the battery type set correctly is important so that the Petrel
can give low battery warnings at the proper voltage levels�
Supported battery types are:
1�5V Alkaline:
The common AA battery type that can be purchased at
most supermarkets and electronics stores around the world� Not
rechargeable� Inexpensive and reliable, they provide 35 hours of
operation� Recommended�
1�5V Photo Lithium:
Fairly common, but more expensive than alkalines�
They provide about 55 hours of operation� Not rechargeable� Good for
use in very cold water� Recommended�
1�2V NiMH:
Common rechargeable batteries used in digital cameras
and photo flashes. Can have high self discharge. Provide about 30 hours
of operation per charge� Can die quickly, so care should be taken to
ensure sufficient charge prior to diving.
3�6V Saft:
The Saft LS14500 lithium batteries provide very high energy
density� However, their high cost makes other battery types a better
choice for most users� Provide about 100 hours of operation� Can die
quickly, so care should be taken to ensure sufficient charge prior to diving.
3�7V Li-Ion:
Rechargeable14500 Li-Ion batteries provide about 35 hours
of operation per charge� Can be ordered from the internet� Have more
gradual voltage drop as discharged, so easier to determine remaining
capacity than NiMH rechargeables� Good in cold water�
NOTE: Battery operating lifetimes are given with screen on medium
brightness and at room temperature� Higher brightness and lower
temperature can reduce life� Lower brightness can increase life�
