Best Budget: Weize 12v 75ah
Why It Made The Cut: Weize has a reputation for producing affordable batteries that offer competitive performance. This 75Ah model offers proven reliability, and the versatility to power a number of small electric vehicles.
Shorter life than premium models Packaging offers minimal protection
The Weize solar battery is another popular AGM model. So it has proven reliability, and is safe to use in any position without risk of spilling acidic electrolyte. It is maintenance free, and works well at low temperatures.
The Weizes compact design, and 75Ah capacity suits a wide variety of functions. It is relatively lightweight at 46 pounds, making it viable for campsite use, and in small boats with trolling motors. It is ideal as a backup for a sump pump in the event of a power failure. It will run a variety of electric vehicles such as golf carts, lawn equipment, and wheelchairs. It can also be used to power emergency lighting.
This batterys lifespan is quoted at around 6 years. While we were unable to find a figure for cycles, it is likely to be around 600 to 700. While these figures are lower than some, the Weize solar battery still represents good value when the low price is taken into account.
That said, we cant speak from direct experience, but we have seen several reports of batteries being damaged on arrival. Most felt this was due to packaging that doesnt provide sufficient protection.
How Long Do Deep Cycle Batteries Last
The lifespan of a deep cycle battery varies by battery types. Normally, AGM batteries lasts about 4-7 years Gel batteries lasts about 2-5 years Flooded Lead Acid batteries lasts 4-8 years, and a high quality Lithium battery can last more than 10 years. The lifespan of a deep cycle battery also effected by battery cycles, maintenance, and the environment in which the battery is kept. For example, a Lead-acid batterys cycle life can range from 500 to 1200, and a lithium battery can range from 2000 to more than 5000. Besides, a battery kept in a hot environment will experience a shorter lifespan than that in a cooler environment. The lifespan of marine batteries, RV batteries and boat batteries also depends on its usage scenario.

How Do I Select A Provider
Here are a few things to consider when choosing a solar professional:
- Experience Be sure to find out how long the installer has been in business. An installer recommended by a national solar company will typically be around for the long haul, while smaller installers may come and go.
- Reference Consider getting recent customer references. Check with the Better Business Bureau to make sure that no complaints have been filed, and look at customer reviews on websites like Angie’s List and Yelp.
- Credentials The installer should be licensed, bonded, and insured. You can also ask about certification through the North American Board of Certified Energy Practitioners, or completion of training programs accredited by the Interstate Renewable Energy Council.
- Partnerships Look for installers who partner with brands you know, like national home improvement chains or warehouse clubs. That’s usually a good sign that the company is a safe bet.
- Warranty Look for an installer that offers warranties for your roof, and other critical parts of your system, like the inverter. Ask if they guarantee system production.

The Solar Lithium Battery Advantage
Lead acid batteries may be a cheap buy now, but theyre costly in the long run. Costly because you have to replace them more often than lithium batteries. Costly because theyre less efficient than lithium. Costly because they can kick the bucket early when you accidentally discharge them past 50%.
Those are some good reasons to call it quits on traditional batteries. But is it time to switch to lithium? Heres why solar lithium batteries are worth triple their weight in gold :

Choosing The Right Battery For Solar Panels
There are two main types of batteries on the market:
Devices that use grid photovoltaic and battery inverters. They redirect the excess electrical energy to the battery as well as have the ability to recharge it from the inverter output.
Devices that use battery inverters and DC charge controllers. They send the excess generated electrical energy directly to the grid.
How We Chose The Best Solar Batteries
We researched the products from more than a dozen manufacturers in order to find a selection of different solar batteries, and offer solutions for a variety of needs. The following were the key criteria:
Performance: All but one of the solar batteries we used produces 12 volts of power, so the Amp hour rating is the major difference. Two batteries of the same Ah will deliver broadly similar performance, so we chose a variety of capacities in order to provide suitability for different tasks.
Chemistry: A number of different chemistries are used within solar batteries. While they all perform very much the same when new, some degrade more quickly than others. We have chosen one solar battery from each of the four main types in order to highlight how this impacts on performance and lifespan.
Brand and Price: Some brands are widely recognized as supplying quality products, and in the main we stuck with those who have a long-established reputation for durability a key facet of any battery. That said, price is always important so we have also tried to highlight value for money. The best solar panels and the best solar generators will help you save more money and energy.

Lifespan Beyond 5000 Cycles
Many see the price tag of lithium batteries and immediately walk away. However, one of the most important aspects to consider is how long they last. Typical lead-acid batteries can last anywhere from 200 to 900 charging cycles. Under ideal conditions with proper maintenance, this ends up being a few years at the most with daily solar charging.
Conversely, lithium batteries are known for lasting 5000+ charge cycles, translating to 10+ years of use. For example, Battle Born designs their batteries to last 3,000 5,000 cycles regardless of the depth of discharge and backs their batteries up with a 10-year warranty. This guarantees that 80 percent of the battery will still be available after 5,000 discharge cycles!
Lithium batteries may come with a hefty initial investment but last years longer. Not needing to replace lithium batteries as often makes them one of the most cost-effective options for building a battery bank.
Backup Power For Grid
Lithium solar batteries are great for providing backup power when grid power fails. For those who live in places where natural disasters are common, storing solar energy for a rainy day is a must! Likewise for areas with unreliable power grids.
Using a hybrid solar power system gives you the best of all worlds. You can rely on solar power when its available, grid power on darker days, and battery storage when all else fails. Not only will you reduce your power bill by utilizing solar energy, but youll always be covered in an emergency.

Best Applications For Lithium Solar Batteries
It should be clear by now that lithium batteries for solar energy storage are superior to lead acid batteries in every way except for the higher upfront cost . Here are some specific applications where lithium solar batteries really excel and why:
- Full-time off-grid homes benefit from the ability to do truly deep, daily cycling with a long cycle life for years and years of reliable power.
- Part-time off-grid residences like vacation homes benefit from the lack of maintenance needed to keep the batteries working well despite infrequent use and the ability to install them inside the house to keep them protected.
- Remote cabins and equipment benefit from their light weight, relative portability, and wide ambient temperature range.
- Emergency backup power for grid tied solar systems benefit from the high DoD, which keeps the number of batteries needed to power critical loads at a minimum.

Gel Vs Lithium Solar Batteries
Gel and AGM batteries are two types of lead-acid batteries.
In a gel battery, the electrolyte takes the form of a gel paste. In an absorbed glass mat battery, the lead acid is absorbed into a fibreglass mat.
Both these battery types are safer than flooded lead-acid batteries. They help ensure that the acid cant spill.
However, lithium-iron solar batteries offer better efficiency, greater capacity and longer lifespan. Theyre also safer, with no toxic acid.
