Replacement For The Replacement

Bad news for 2021… Goal Zero is no longer supplying this Yeti 1250 replacement battery.
But, don’t despair! We have another model that fits the Yeti 1250 case, and provides the same performance. Best of all, it’s from a company that’s one of the leading battery manufacturers that we spec for other solar applications.

Want to bring your Yeti 1250 up-to-date?

Consider replacing that worn-out lead-acid battery with a lithium battery instead.
The RELiON RB100 is a drop-in replacement lithium battery for Group 31 AGM SLA batteries.
It has been designed to be comfortable with the same charging system that your Yeti features.
But instead of 600Wh of useable storage, 500+ cycle-life, and a gimpy hip lugging your Yeti 1250 around, you can have over 1,100Wh of storage, 4,000+ cycle-life, and half the weight.
