Replace The Batteries In Your Goal Zero Yeti Power Station
Batteries are batteries, they don’t last forever. Especially in something like a power station that some might use every day. Goal Zero advertises that their lead-acid AGM battery used in the Yeti 400 has a lifecycle of 4-6 years, or 500-800 cycles before it should be replaced.
But if you travel fulltime in an RV or van and use it every single day, you might go through 300 cycles in a year, and then the battery would only last for about two years before you would notice that the battery won’t hold much of a charge any longer.
An easy way to fix the damaged battery is to replace it with a new one. That would make the Yeti function like new, and you could use it for another couple of years.
Which Goal Zero Yeti Can You Replace The Battery In?
Unfortunately, not all of the Yeti power stations support an easy battery replacement by the user.
You can replace the batteries in the Yeti 150, 400, 400 lithium and 1250.
You can not replace the batteries in any of the other Yeti Lithium power stations.
Replacement batteries available
Goal Zero sells replacement batteries, but you can also buy other brands. Here are a couple of battery replacements that are actually upgrades compared to the original battery, and they have no issues fitting the cases.
Yeti 150 – Replacement battery VMAX 15Ah 12V – 1Ah larger than original
Yeti 400 – Replacement battery VMAX 35Ah 12V – 2Ah larger than original
Yeti 400 Lithium – There is a Mighty Max replacement battery but I can’t find it in stock anywhere.
Yeti 1250 – Replacement battery VMAX 125Ah 12V – 25Ah larger than original
How do you replace a Yeti battery?
Goal Zero has videos about how to replace batteries in each of the Yeti power stations that it’s possible with.
So am I screwed if I have a Yeti Lithium that won’t hold a charge?
If you have a 200X or 500X Lithium there is not much you can do.
If you have a Yeti Lithium power station 1000 or larger you can’t replace the battery right now, but you can add an expansion kit that increases the capacity of your power station.
For some reason, the expansion kit batteries are lead-acid AGM batteries and not lithium, so you would have to take care of them more than with lithium and not discharge it below 50%.
Here is a video from Goal Zero on how their Link expansion kit works.
How do I make the Yeti battery last longer?
While the AGM batteries above are high-quality lead-acid batteries, they will hold a charge longer if you take care of the battery.
One way to do that is to not let it discharge to under 50%. It sounds bad that it can only use half of its capacity, but you can get more cycles out of it by doing so. This is where lithium batteries have a huge advantage since they’re OK to discharge further.
Is Goal Zero going to release replacement batteries to the Yeti Lithium power stations?
That’s a question only Goal Zero can answer. Maybe their future Lithium solar generators will have more user-replaceable builds and batteries, but that’s just an optimistic guess.
