Frequently Asked Questions
What type of battery is in my Goal Zero Yeti?
Your Goal Zero Yeti uses custom designed Lithium Ion. Here are some basic facts about
Lithium Ion batteries:
1. Lithium Ion batteries can store and release a lot of energy in a short period of time.
The batteries in your Goal Zero Yeti are in a protective enclosure with a sophisticated
battery management and protection system controlling its terminals to the outside
world.
2. It is critical that your battery does not get wet as moisture and water can get into the
battery cells behind the protection circuitry and bypass that protection.
Can I replace the battery in my Goal Zero Yeti?
Yes, the battery inside the Goal Zero Yeti is designed to be easy to replace.
1. Turn your Goal Zero Yeti upside-down and place its top surface on towel or blanket
over a hard surface.
2. Remove the 10 screws on the bottom plate.
3. Unscrew the 2 bolts that connect to the battery terminals.
4. Pull on and disconnect the data connector to the battery.
5. Remove the 8 screws holding the battery pack to the Goal Zero Yeti.
6. Lift the old battery out of the body of the Goal Zero Yeti
**This battery is HEAVY. Use caution and proper technique when lifting.
7. Insert replacement battery and reassemble in reverse order of steps above.
8. Replaceable batteries will be available from GoalZero.com. Call us at 888-794-
6250 for assistance.
How do I know if my Goal Zero Yeti is charged?
To check the charge level of your Goal Zero Yeti, refer to the LCD Battery Display. When lit
up, you'll see a battery outline with 5 segments, indicating the current charge level. It is OK
to use your Goal Zero Yeti even when it's not fully charged.
Why is the light on the AC button blinking?
A blinking light on the AC button indicates that at the current load, the AC inverter will
12
be shutting off soon; you should also see RESERVE MODE blinking on the display.
Recharge your Goal Zero Yeti as soon as possible to continue powering your device.
Once the AC inverter has shut off, the Yeti will attempt to reset itself three times. After
three attempts, the AC inverter will remain off until you physically reset it by pushing the
AC button or by recharging the battery a small amount.
How do I know if my device will work with the Goal Zero Yeti?
First, you'll need to determine the amount of power your device requires. This may require
some research on your end, a good internet search or examining the user guide for your
device should suffice.
Second, you will need to check the capacity for the individual output ports. For example,
the Goal Zero Yeti's AC port is powered by an inverter that allows for 1500W of power.
This means if your device is pulling more than 1500W for an extended period of time, the
Goal Zero Yeti's inverter will shut off. Another number to watch for is the surge rating of
your device as compared to that of the port. The Goal Zero Yeti inverter has an advanced
surge management system that will maximize its compatibility with various devices, but
there will still be items that will surge at a higher rate, and for a longer time, than the
Goal Zero Yeti can manage, in which case the port will turn itself off.
Finally, once you know your device is compatible, you'll want to determine how long you'll be
able to power your gear from the Goal Zero Yeti. Here's a quick and dirty lesson in power.
All GOAL ZERO power packs and solar generators have a number in their name, ex.
Guide10 Plus Power Pack, Goal Zero Yeti 1400. These numbers refer to the Watt Hours
(Wh), or the amount of energy that can be stored in each recharger, and how you'll know if
your gear is compatible with each recharger. For example, a 200Wh recharger should run
a 100W light for 2 hours (200/100=2). If your gear falls within the 1400Wh capacity of
the Goal Zero Yeti, you'll want to check the restrictions on each of the output ports.
Another factor in the math is how much power is being converted going from the Goal
Zero Yeti battery to the device you are powering/charging. In some situations, like when
running a 12V device, such as the LAL 350, directly off the 12V port, there will be no
conversion and so no additional losses. In using the USB ports to charge a phone, you
add a layer of conversion (12V battery in the Goal Zero Yeti is being converted to a 5V
