Why is WEIZE one of the best-selling deep cycle batteries?

Well, at 12.09 x 6.65 x 9.17-inch size, Weize brings high performance, long service life, and deep discharge recovery. 

It’s best suited for power wheelchairs, solar marine and off-grid applications, boats, solar wind deep cycle, and more.  The Weize 55ah battery is somewhat smaller than the average car battery; hence it fits in more places.

For example, a wheelchair that needs a 12 volt 35 ah battery would work with a 100ah instead?  That brings us to the size of the battery you need.  At 12v 100ah sealed lead acid rechargeable AGM, deep cycle; the Weize will increase your ampere-hours.

What are past users saying?

Its bolt-on battery terminal (using it on boa trolling motor) lasted longer than any other deep cycle battery.

The battery works perfectly and offers a good power/weight/cost ratio when built with a solar generator for camping—besides, the user-powered electronic devices, lights in camp for the weekend before needing to recharge.

It brings good runtime depending on the power equipment speed setting. But with its size, it’s suited better for smaller trolling motors. Weighing at 34.2 pounds, 12V, and 660.00 watt fits in Universal for most purposes and is maintenance-free.

What To Look For When Buying A Deep Cycle Battery?

Deep cycle batteries are intended for powering an application for an extended period.   Lithium-ion tech has become a trendy deep cycle battery choice for marine watercraft, RV, golf cart, lighting, and similar. But what are the main factors to consider when buying a deep cycle battery?

Weight and size

Deep cycle battery weight is quite important; it should be lightweight and energy-dense.  A smaller, lighter battery gives you more flexibility when considering your application’s total weight and balance. Yet, lithium-ion has high energy efficiency for better performance despite being small and light.

Charging time

The battery choice must charge faster, nearly because charge time is critical for us.  Fast charge time is best to get you back on the move as quickly as possible– think all-terrain vehicles (ATV), marine power, and other recreational vehicles.  Deep batteries fully charge in one session, which makes the charging process more comfortable and reliable.

Electrical usage

What is the amount of energy you will be consuming per day?  This will be determined by the number of appliances or electronics in your RV.  Usage determines the size required and the dimension of the deep cycle battery.

Depth of discharge

The DoD of the deep cycle battery bank is the limit of energy withdrawal to subject the battery.  It is expressed in percent of the total capacity. The further you discharge a battery, the fewer cycles the battery will be capable of completing. Deeper discharge shortens battery life and also influences the deep cycle battery amp-hours.

Deep cycle battery ratings

You need to understand in-depth cycle battery ratings for the best deep cycle battery amp hours and volts. Amp-hours (Ah) is the capacity available in chemical energy inside the battery converted into electrical energy.  The amount of energy the battery can store affects the discharge rate.  A good deep cycle battery can discharge C100, which is quite impressive.

Amp-hours means that the battery can provide 1 amp for an hour. It is inversely related, so a 1 amp-hour battery can provide 20 amps for 3 minutes (which is 1/20th of an hour). This comes in handy when you’re trying to see how long you can power your appliances for. 

For example, if an appliance pulls 10 amps, and you have a 100 amp-hour battery, you can run the appliance on the battery for 10 hours. Most deep cycle batteries come with real ratings, which specify whether your deep cycle battery would last for 20 or 24 hours.

What are the Different Deep Cycle Battery Types?

Sealed lead-acid batteries

Sealed lead-acid batteries are also known as maintenance-free batteries.  They have no liquid that spills from the inside if the battery breaks. It has enough liquid that allows the electrolytes to flow.  The easiest way to tell if your battery is sealed vs. not sealed is to lightly shake it and listen for liquid. If nothing is sloshing around, it’s a sealed battery.

Flooded lead-acid batteries

It’s a type of deep cycle battery that contains liquid in an unsealed container.  A flooded lead-acid battery must remain upright and in an area with adequate ventilation. The battery requires monitoring and topped with distilled water.  A flooded lead-acid battery is best because it’s more affordable, easier to troubleshoot, and it deals with high surge current.

Flooded lead acid batteries are also known as wet cell batteries. The cap at the top of the battery is used to add water, which is the reason these batteries need to be kept the right way up. Although flooded lead acid batteries are more affordable, the maintenance required is a lot more than sealed lead acid batteries.

AGM batteries

It is the best deep cycle battery with an absorbent glass mat that absorbs the fiberglass mate’s electrolyte. This allows it to handle higher temperatures and self-discharge more slowly.

For the most effective use of the glass mat, it is placed between the two plates inside the battery. AGM batteries are not filled with electrolytes until the brim. 

There are several advantages of using AGM batteries. Unlike flooded lead acid batteries, AGM models can be placed upright as well as on their sides. If your work involves extreme weather conditions, AGM batteries will even work underwater and are completely immune to leakage.

Gel batteries

A gel battery (gel cell) is a sealed valve-regulated lead-acid deep cycle battery that uses gel electrolyte. It doesn’t need to be positioned upright.  A gel cell eliminates evaporation of the electrolyte, spillage, and corrosion issue and boasts a more excellent resistance to vibration, shock, and temperature.

They take longer to charge than an AGM battery, which can be a disadvantage if you’re in a time crunch. Overcharging these batteries might also cause them to lose battery capacity in the long run.

Lithium-ion Batteries

Lithium-ion is quite different from the conventional deep cycle battery above, featuring grid-connected residential energy storage. These types of batteries can be found in most of your electronic devices, including phones and laptops. Li-ion batteries feature a high energy density and low self discharge rate, making them a perfect fit for electronic devices. 

The reason Li-ion batteries are named this way is because they provide electricity with the help of moving lithium ions through an electrolyte. The ions move from the negative to the positive electrode when the battery is being discharged and from the positive to the negative electrode while it’s being charged.

What is the Difference Between a Starting vs. Deep Cycle Battery?

A starting battery is made to crank an engine with a momentary high power burst to get it started like your automobile.  A deep cycle battery is designed to produce continuous power for a wheelchair, sump pump, or golf cart.

Another difference between a starting battery and a deep cycle battery is that the former will give you a higher amount of peak power. If you want a lower power output for a longer time, you should pick a deep cycle battery. 

A number of vehicles like trucks and buses come with a combination of starter and deep cycle batteries to provide both peak output while starting the vehicle as well as continuous power for powering up the onboard electronics.

What is the Difference Between Deep Cycle vs. a Cranking Battery?

A deep cycle battery is made differently than a cracking battery with thicker and more sizable plates. A cracking battery has more, yet thinner, plates that produce a fast voltage spike to crack an engine and maintain high power output for long periods.

What is the Difference Between Deep Cycles vs. a Marine Battery?

You can’t use a starting battery for trolling motors or powering appliances. The marine cycle batteries are built to discharge slowly over a long period of time while withstanding several hundred charging and discharging cycles. On the other hand, a deep cycle battery cannot be used for starting a motor or a sump pump.

Deep Cycle Battery Reviews

The best deep cycle battery should meet your specifications and heavy-duty.  You need one that can service a solar panel system, an RV, or any other related application.
