This means three things:
-
It is hard to estimate level of charge.
The battery shows a steady 3.6V for most of its life - there is no
slow battery voltage decrease that can inform your KAON about the amount of power that has been
used and the amount of power left.
-
It is hard to estimate the amount of time left.
Even if your KAON knew exactly how much battery
power is left, it is still hard for your unit to judge how much dive time is left. Dive time will be greatly
affected by user settings such as
screen brightness
and
colors
.
-
Once the battery voltage starts to drop, it drops fast.
Your KAON will stop functioning entirely once
the voltage drops below 2.90V.
For all of these reasons, it is important to pay attention to the
Yellow
battery indication - it means there
is really very little time left.
Basic Rules For Optimizing Battery Life
You can extend/optimize your battery life in several ways:
-
Always choose the lowest screen brightness setting you need for your dive. The KAON has an
"Auto-Dim" feature, where the unit uses your chosen brightness setting on the surface, and slowly
reduces brightness to Low as you descend to a selected depth.
-
Keep battery life in mind when setting screen colors. The OLED screen is an RGB screen, which
means it has red, green and blue pixels. To display the color green, for example, it only needs to light
up one pixel - the green one. To display any other colors, the screen must light up a combination of
pixels. To display white, it must light up three pixels, full-force. Therefore, the most economical
display colors would be red, green and blue. The least economical display color is white. The standard
Liquivision display color scheme is designed to balance readability with economical battery use.
Detailed Rules For Optimizing Battery Life
1. Brightness
. Brightness has the biggest effect on battery life. As a general rule, HIGH brightness
gives you HALF the battery life compared to MEDIUM brightness. Similarly, MEDIUM gives you
HALF the battery life of LOW. This means that LOW brightness gives you FOUR TIMES more
battery life than HIGH brightness. The best way to optimize battery life is the “Auto Dim” feature.
2. Colors
.
Colors have a dramatic impact as well. Primary colors (pure green, pure red, dark blue)
consume the least battery power. Compound colors such as yellow, orange, and gray burn more battery
power. Compound colors (those that require all three colors), such as light blue and light gray, burn the
most battery power. You should use compound colors with caution.
3. Refresh rate
The Fast refresh rate burns about 20% more battery power than Normal. So battery life on "Fast" is
reduced by about 20%.
.
The refresh rate changes how fast information is updated on the screen. It has two
settings, "Normal" and "Fast". If you can use Normal and you don’t notice anything, that is the best
choice. If you use Normal and you find that you can see the screen flickering when you move the unit,
then select Fast. Also, if you plan on taking any pictures or video of the KAON, select Fast.
