What type of battery is in my YETI?
Your YETI uses a Group 31, 12V, 100Ah, sealed lead-acid battery (AGM),
similar to what is found in your car. Here are some basic facts about AGM
batteries:
1. AGM batteries should be kept full at all times.
This means you should leave your YETI plugged into a power sources at
all times, especially during storage.
2. AGM batteries last longer if you do not drain them completely.
This stems from the “battery memory myth” in old rechargeable batteries.
You can read more about this in the Battery 101 section.
Can I replace the battery in my YETI?
Yes, the battery inside the YETI is extremely easy to replace.
1. Remove the four bolts holding down the top of the YETI.

current charge level. You can turn on the Battery Display by pushing the
Master POWER button. It is OK to use your YETI even when it’s not fully
