windynation 12v deep battery

If you’re looking for a cheap yet powerful deep-cycle battery, you have come to the right place.

In this article, we will discuss the WindyNation 100AH 12V battery. We will look at the various features it provides in detail and then we will try to determine if this is indeed the perfect battery for your applications. 

One of the best features of this battery is its size. This is probably one of the smallest 100AH batteries in the market that provides great quality, all packed in a small yet durable casing. The battery comes with a 1-year warranty too which is quite reassuring.

The battery exhibits an AGM technology, very popular these days and thus has an extra long battery life.

Let us now discuss and understand some of the features of this battery in detail.

10 Best AGM Battery Of 2024

Deep Cycle Capacity

One of the key features and the reason you’re considering buying this battery is probably its deep cycling power. For those who do not understand what deep cycling means, it is basically the capacity of the battery to provide a steady amount of current for a long period of time.

Car batteries do not have this functionality. They are meant to provide high currents instantaneously and thus get discharged very quickly. Such batteries are called cranking batteries or starting batteries. 

Deep cycle batteries such as the battery in consideration, do not have such features, however, is excellent for other purposes such as use as a UPS battery, inverter battery, etc.

Deep cycle batteries are also used in electric vehicles such as electric bikes, marine vehicles, etc. They also find applications in solar units and RVs. 

Technically, the property that gives deep cycle batteries this ability is the internal chemistry.

Deep cycle batteries, unlike starting batteries, can discharge upto 80% and still provide power. This also makes them unfit for starting engines and other such load-intensive functions.

AGM Technology

With time, all brands are slowly moving on from traditional to AGM batteries. AGM or Absorbent Glass Mat technology eradicates the need for any maintenance as there is no liquid electrolyte inside the cell and hence no need to refill.

The batteries are completely sealed and there is no emission of harmful gases which makes the battery a lot safer and greener to use.

AGM batteries are also vibration resistant and can be used for rough lands. They also have a longer lifespan than traditional batteries.

AGM batteries are composed of lead plates surrounded by glass fiber containing the electrolyte. AGM  batteries can have a lot more cycles than regular batteries and are really easy and safe to use.

For that reason, these batteries are used in all areas from transport to telecommunication and everything in between.

WindyNation 100AH 12V AGM Drawbacks

One of the few drawbacks of the battery is that it is really a bad battery if you need it as your starting battery for your vehicle.

It can probably work just fine with most simple engines but it is recommended to use a better battery if that’s your requirement. 

Secondly, the battery has mixed reviews from users and that is one thing to think about. Other than these tiny setbacks, the battery seems like a pretty good investment.

If you want to use this battery for your home inverter system, you may need multiple of these batteries to cope with a load of all the appliances.

In that case, it is a better idea to compare and understand your budget as you may have to spend quite a lot.

Also, the battery does not feature any fast charging feature which can be a problem for some consumers.

WindyNation 100AH 12V AGM FAQ

How many amps can you draw from a deep-cycle battery?

This depends on the Amp-Hour rating of the battery. For example, if you have a 100Ah battery, it means 1 amp for 100 hours or 10 amps for 10 hours and so forth.

Appliances that usually do not draw a lot of power can last for a long time using deep-cycle batteries. For example, with a 100Ah battery, a bulb that draws 60W at 12V, would last for
20 hours.

How many solar panels does it take to charge a 100-ah battery?

This will depend on the solar panel. If your solar panel is rated at say 120W at 12V, it will take 10 hours to fully recharge a 100Ah battery.
However, it could be unsafe to use high currents to charge a battery. Moreover, solar panels having standardized values only are available in the market and you may have to use a combination of batteries and panels for a smooth result.

Can I run a deep cycle battery and a starting battery in parallel?

Technically, it is not impossible. However, you must make sure that the batteries are of the same type otherwise you may have to face issues in the long run.

Final Words

This is an excellent 12v battery if you need deep cycle functions however the battery is unfit for starting or cranking functions. 

The battery can be ideally used in solar power units, inverters, UPSs, and as a secondary battery for RVs for the best result.
