Thanks for the feedback. For my needs it is hard to beat at that price with the Yeti 400 going for $460 retail. Hopefully, someone soon with figure out a way to reduce the cost of high density Lithium batteries for expedition applications.


I own two of the 350 no issues yet ?
sorry no idea on battery replacing ? I would think take it apart find the battery type and replace ? or so I hope when it comes time :)

I wold go for best price for sure :)

you can read my early thoughts not enough to run my fridge ? i just went cheap battery box and large 105 trolling battery and simple plug and good to go want a fancy larger box one day but I use my 350 for camera gear computer stuff and lights etc..

yeti 400 seem cool though but if its much more ? its all just looks more so it seems

I was able to order one of the last 350s and look forward to experimenting with it. Worst case I will chain it to a Yeti 400 in the future.

How much are the replacement 350 batteries? I have also heard the 350 and 400 use essentially the same battery?
Also, if the 350 battery is replaceable I can replace it if needed.
Opening up the Goal Zero Extreme 350 is pretty simple.
If you can find a replacement battery changing it out should be easy.
Googling "Ritar RA12-33" shows that a replacement battery is about $70
Here is what it looks like.

Yeah, my battery is kaput.
I could actually fix my 350 with a new one, and have it for a spare project.
Pretty much was not going to use it again though since I have the ArkPac.

FYI Costco is doing goal zero road shows this month. They offer about 25-30% discount based on last years prices, when I purchased an extreme 350 for $299 vs $370 and a 30 watt panel for $179 vs $239. Advantage is longer return policy at costco and satisfaction guaranteed vs 30 days w/Goalzero.

Schedule is here http://www.costco.com/goal-zero-schedule.html

After 3 years of use, my Extreme350 isn't powering my fridge like it used to. But I think this is due to my neglect from not keeping it charged up. I left it in my rover for 2 months with no charge, not a smart thing to do with a lead acid battery. I charged it up before this weekend in Yosemite, but it was out of charge by the morning running the fridge.

I am going to get a replacement battery, thanks for posting the brand.

But I heard GZ upgraded the battery or changed brands between the 350 and Yeti 400. Anyone know about the upgraded battery?

Based on the previous posts, new batteries are under $60. I am definitely keeping the 350 going as it has worked very well for me the past few years. It is a lead acid battery, just like a car battery so don't expect it to last forever. I just replaced my rover battery after 4 years as well. Stayed with the Costco deep cycle, which is now interstate, so I just plugged the fridge into the main battery this weekend and fired the truck up once a day to be sure it was topped off. I didn't bring my solar panels as we were packed with 2 adults and 3 kids and it was just a weekend trip.

After doing some research, found the Yeti400 is the same battery as the Extreme350, Ritar RA12-33. I found a vendor on eBay selling an 'upgrade' sealed AGM battery VMAX857 with 35mah and states a higher quality battery. I will probably buy this upgraded battery. Many good reviews of the battery on amazon from the fishing community who use it for trolling.

I also came across some info on the GZ website stating that you should NOT drain the battery through the Anderson power pole connectors as they are designed for chaining multiple batteries but do not protect the battery from excess drainage. This could be why my battery isn't working properly as I use a Anderson connectors directly to my ARB. I may go back to using the 12v cigarette plug to run the ARB from the Extreme350 while in camp and use the Anderson plugs for running the ARB while on the trails and the Anderson plugs for recharging the GZ while driving.

Will report back.

I talked with GZ customer service. Though the lady didn't sound like an expert, she said I should be able to use the Anderson plugs without issues since they have adapters to power 12v device directly from those ports on the Extreme350. But it looks like that is different for the Yeti.

I ordered this battery from Amazon as it was the same but cheaper than the eBay. http://www.amazon.com/gp/product/B00F8Q0VTQ

Will report back when it arrives and I rip apart my Extreme350. The battery has many good reviews from fisherman using it as a trolling battery.

While not the original intention of this thread, it now seems to be the focal thread for battery replacement advice.
Cool to see the Yeti 400 also uses the RA12-33.

@spikemd created a seperate thread discussing the compatability of the VMAX 857 battery in the Extreme 350.

That battery is listed at $120 right now but it looks like it occasionally dips to $110

I'll be grabbing a 35ah replacement from my local Battery Mart for about $80. Will report back later how it works out.

I just noticed in the much longer thread about the Yeti 400 that you can buy a replacement 33ah battery directly from Goal Zero for $80 + s/h.

I tried three batteries from Battery Mart which were all very closely sized to the original RA12-33 and none of them actually fit.
They were the SLA-12V35, SLA-12V35-INSERT and SLA-UB12350FR.

Ended up ordering a replacement directly from Goal Zero. Using the promocode "FREESHIP5" it got down to $75.99 with free UPS ground shipping.

Sorry I didn't update this thread earlier. Please follow the links above.

DO NOT DISCHARGE THE YETI/EXTREME DIRECTLY FROM THE ANDERSON PLUGS!

The Anderson plugs are for chaining only and do not provide any battery protection for over discharging. I think that is why my battery died in the Extreme. I am making some 6mm to Anderson adapters to utilize the protection built into from GZ. I am also looking into buying another 35ah battery to connect to the Extreme or a new Yeti and chaining it to the Extreme to double my capacity to almost the equivalent of a Group 31 yellow top.

The battery I bought, a direct replacement and small upgrade (35ah vs 33ah), from amazon: http://www.amazon.com/gp/product/B00F8Q0VTQ
