BATTERIES 101: Goal Zero utilizes the latest and greatest in battery technology to accompany
you on all life's adventures. From the versatile and lightweight Lithium-ion, to the robust and
powerful Lead Acid, we've compiled some helpful tips to keep your Goal Zero batteries working their
best.
i. Batteries need exercise.
The best thing for any battery is to use it. Don't leave the battery sitting without being charged for
extended periods of time. If you will be storing the Goal Zero Yeti without a charger, make sure it's
fully charged before you put it away.
ii. The "Battery Memory" myth.
Thanks to old Nickel-Cadmium (NiCd) batteries, there's a myth running around that you should
completely drain your batteries before plugging them in for a recharge, called "deep cycling". Although
true with NiCd batteries, the typical batteries you'll find in most of your gear today, including the
advanced lithium and lead-acid batteries used in your GOAL ZERO PowerStation, require no such draining.
In fact, you should avoid deep cycling your batteries – it does more harm than good in most cases.
iii. The "Stadium Effect".
The stadium effect occurs when recharging your batteries. You'll notice your battery quickly
beginning, then slowing down noticeably when trying to charge up the last several percentages. Think of
how quickly a stadium fills up when the doors first open – there are hundreds of open seats so it's easy to
find the one you want. Eventually there are only
a few open seats here and there and people have to maneuver around to find the spot they want and
filling those seats takes longer. The same theory applies to recharging batteries. It's easy for energy to
flow in and take up empty space in the beginning, and as time goes on and there is less space available, it
takes longer for the energy to fill in the holes.
iv. Read the manual.
It might be a long read, but the manual is the best place to find the do's and don'ts for the battery in
your specific device. Reading your manual will ensure you're taking steps to keep your batteries happy
and healthy.

SOLAR 101: GOAL ZERO makes it easy to recharge your gear from the sun – we didn't invent
solar power, we perfected it. Some things to keep in mind when recharging your gear with solar
power:
i. Solar panels don't store power from the sun, they collect it.
We teach you to COLLECT– STORE – USE, which is the best way to utilize solar power to recharge your
gear. COLLECTthe sun's energy with a solar panel. STORE the power in a Power Station. USE the Power
Station to power your gear, day or night. If you're really
the junction box located on the back of our NOMAD Solar Panels to recharge from the sun.
ii. Not all solar charge times are created equal.
Most solar panel manufacturers calculate their recharge times with the following equation: Device Watt
Hours/Solar Panel Watts = Solar Recharge Times. So theoretically, a 13 watt solar panel would recharge
a 50 watt-hour recharger in 3.84 hours (50/13 = 3.84) – and this is the number you could find in
marketing material for a solar panel. However, in order to standardize results across all manufacturers,
these tests are completed in laboratory
settings. The truth is, on a good, sunny day, you'll receive about 50-75% of your solar panel's rated
wattage, and this is how the engineers at GOAL ZERO calculate the solar recharge times you see on our
packaging.

iii. Solar works, even in overcast conditions.
Solar panels utilize IR, UV, and visible rays from the sun that can penetrate through clouds. Although the
efficiency of the solar panel will decrease in cloudy conditions, you'll still be collecting valuable power
from the sun.
iv. Proper alignment works wonders.
Keeping your solar panel angled toward the sun can dramatically increase solar efficiency.
