We’ve tried to cover most of the popular models of the ace brand in order to equip you with the relevant information in a condensed form so that you can take an informed decision.

In the present article, you’ll find answers to the most common questions that arise when there’s a dip in the performance of a Goal Zero Solar Generator.


Can You Replace the Goal Zero Solar Generator Battery?

There’s not much doubt in the fact that Goal Zero is the market leader in the production of solar generators. They manufacture various types and capacities of solar generators to meet the requirements of different users.

With continued usage, the power proficiency of these generators is found to decline. The most common cause of this reduction is the lowering of the battery’s ability to store power due to various reasons.

One question that the users of these generators have is whether the batteries of the generator can be replaced or not. If you have a similar question in your mind, you’ve come to the right place. The one-word answer to the query is “Yes”. The Goal Zero Generators are manufactured keeping these future requirements of users in mind. The lithium batteries of the generators are replaceable.

There are many batteries available in the market claiming to be replacement batteries for Goal Zero  Yeti Solar Generators. However, you’ll need to be careful in selecting the right battery as apart from the volt, amperage and other technical specifications, the size of the battery and the connections should be checked for perfect match. The following are the critical factors to check before purchasing a battery for your solar generator .


 (a) Compatibility  The battery’s specifications should be compared to those of the generator to ascertain that the two of them are congruous with each other. The dimensions of the battery need to be checked to confirm that it’ll perfectly fit into the space available. The connecting lugs of the battery must be such that the joints are well matched.


 (b) Leak Proof  The chemicals inside the battery’s body are dangerous as are the fumes and gases produced due to the chemical reactions. If these leak out of the battery, it’ll not only reduce the battery’s capacity, but also pose health hazards for the users. Therefore, it’s of utmost importance that your battery should be completely leak-proof.


 (c) Ease of Installation  This may seem like a trivial point to many, but it’s an important point. An incorrect installation may not only damage the battery and the generator, but may even prove to be dangerous for you. If the installation process is complicated, there are more chances of mistakes. Hence, battery manufacturers also make it a point to provide batteries which are easy to install.

Why to Replace the Lithium Ion Battery of a Goal Zero Solar Generator?


 1. Normal Life:  The lithium-ion batteries store energy in the atomic bonds of lithium. Although they’re rechargeable, the life of a normal Li-ion battery is only two to three years or 500 full usage cycles, whichever occurs early. A full cycle is from full charge to complete discharge and then full charge again. It works best when it’s taken to only incomplete discharge rather than deep or full discharge. As it doesn’t have any charging memory, there’s no harm using it up-to partial discharge.


The life of a Li-ion battery diminishes even when it’s not in use, so the battery needs to be replaced after a maximum of 3 years, irrespective of its usage. Apart from the normal reasons mentioned above, the life of the Li-ion battery also reduces every time you accidentally discharge it completely. Overheating due to external heat or excessive charging also reduces the battery’s life. Once the power storage capacity of the battery starts dropping, it’s best to replace it to get the optimum output from your Goal Zero Generator.


 2. Enhance Power Capacity.  Sometimes there may be a requirement to increase the capacity of the battery to meet additional power needs of users. The Goal Zero Solar Generators generally have higher power generation capability than the battery provided with them. This extra power potential can be tapped by using a higher capacity battery. Hence, the battery might have to be replaced to achieve a higher power capacity.


Why Change the Generator, When Only Battery Needs Replacement?


The solar generator consists of different components including solar panels, charge control device, battery etc. The battery is the most vulnerable part of the system that leads to majority of problems.


The other elements of the generator will rarely go bad and have much longer service lives. However, the users are generally not aware of this. In case of some issues with the generator, due to their ignorance, the users tend to go for replacing the entire generator, even when it’s just the battery that needs to be changed.


This unnecessary expenditure can be easily avoided if you check the battery’s efficacy. This can be easily done by keeping a track of the power capacity of the generator. Therefore, with simple monitoring of the generator’s power capacity, you can avoid spending extra on the purchase of a new generator.

  1. Hi Chad. Will the VMAX SLR 125 chain to a standard Yeti 1250? I bought one to chain to it through the GZ ring terminal adaptor. I’m not sure if it’s charging up or not. There are some small 4-8 v bursts of input registering- would that indicate a slow float charge? Thank you!

  2. I have a zero 500 that has 432 cycles. And is over 3 years old. What type of replacement battery can I get and still use the 100 watt solar panel?
