Costco Depp Cycle Battery: Everything You Need to Know.

By Mark on May 28, 2018

What is Costco Depp Cycle Battery?

These are lead-acid batteries whose chemical reaction produces the voltage that generates electricity. The battery has the capacity to last longer when compared to other battery types under the same conditions.

The capacity of the energy storage can discharge 45% and higher and can also function steadily when the energy storage remains 20%. These energy features make the deep cycle battery the best for a steady power rate when traveling a long distance. Furthermore, another great advantage of the RV batteries is in their ability to recharge many times through several cycles after they have been discharged.

Measuring the capacity of these batteries is in Amps-Hours (AH). There’s another medium of measuring the capacity of this type of batteries, it’s done with the Reserve Capacity (RC). This is the battery length of time that it can sustain 25 amps load, measured in minutes.

You can determine if the battery is in good condition or not by checking its AH or RC ratings. Better and reliable battery is known by its higher ratings. It is advice that you compare the ratings very well when choosing a battery, so you can get a value for your money. More so, purchasing a deep-cycle battery at a lesser price when compared to other batteries in the store can only be achieved with Costco.

STRUCTURE OF DEEP CYCLE RV BATTERY COSTCO

The categories of the deep-cycle batteries are mainly two which are: Valve-Regulated Lead-Acid Batteries and Flooded Batteries. These two main categories are further classified into another two sub-categories, these are:

VALVE-REGULATED BATTERIES

#A: Gel Batteries
#B: Absorbed Glass Mat Batteries

FLOODED BATTERIES (FLA)

#A: Flat Plated Batteries
#B: Tubular-Plated Opzs

Despite the fact that Costco deep cycle batteries have different types that are supplied, yet the internal structure of the batteries are the same. Let’s check them out:

#1: PLATES (BOTH NEGATIVE AND POSITIVE)

The materials used to manufacture these plates are lead, alloy, and calcium. The function of these plates is to make sure that the release of electric gas is increased.

2. ELECTROLYTE

The electrolyte is the material stimulant between the battery’s negative and positive terminals that conduct electricity. It constitutes of special additives mixed with pure sulphuric acid and pure water.

3. DUMMY PLATE

The manufacturing of the dummy plate is done by the experts; fabricating it out of glass fiber of high quality. It’s solely meant to absorb the whole reserved electrolyte and stops short circuit from taking place between the negative and positive plates.

4. TERMINAL

It improves on how durable and reliable the battery is, through the increase of discharge magnification. Aluminum alloy is the material used in making the terminal and it easily makes contact with the battery’s pin.

5. POLE CONFINEMENT

It works mainly to disallow the leakage of the battery’s acid. Thus, two colored seals are used; red which symbolizes the positive pole and black which shows the negative pole.

6. SHELL AND ITS COVER

This component maintains a sufficient mechanical strength to hold together the pole clusters that consists of different plates. This component is made from Propenyl cyanide or vinyl, butadiene styrene and inter-polymer synthetic resin.

7. EMERGENCY VALVE

It prevents the acid mist from escaping and the entry of oxygen into the battery, in order to maintain the adequate pressure in the storage battery. When the atmospheric pressure inside the storage battery exceeds normal level, the valve will automatically open to let out the excess gas in the storage unit. The emergency valve is made with a high-quality and excellent rubber, which makes the battery life elongated.

APPLICATION OF COSTCO DEEP CYCLE BATTERY

Because of the undeniable great features that Costco Deep Cycle Battery possessed, it is therefore useful in many ways. Its application includes its use in the recreational vehicles, motorized wheelchairs, sailboat, traffic signals, etc.

This 100 AH battery is a perfect fit for those requiring Off-Grid Power i.e. Solar, UPS, Telecommunications and so on. It has a reserve capacity of up to 240 minutes and does not require any maintenance.
Using this battery is safe as it does not emit any dangerous fumes and is an AGM lead-acid battery. The floating life of this item (life-expectancy under continuous charge) is considered to be 10-12 years meaning it is very efficient coupled with the fact that almost 100% pure lead results in a low discharge rate which works well with lead-acid batteries.

Although it costs more than some of the others on this list, this battery also has a 30-day money back guarantee with a warranty for a year. It is rechargeable and can be placed in any position. A unique aspect of this battery is the resistance to shocks and vibrations coupled with consistency in performance regardless of whether the temperature is low or high. It has deep discharge recovery that is essential for any deep cycle battery, along with a long service life. It is an SLA and AGM battery ensuring that there will be no spelling issues.

What this beauty lacks in affordability, it makes up for in power. It is a heavy-duty battery equipped with military-grade custom-made plates. For a heavy-duty battery, it still has a floating life of about 8-10 years which is amazing.
Safety of usage is assured as it emits no harmful gases or fumes. Best of all, it has 99% re-combination capabilities meaning the output voltage and current is relatively higher than in other batteries which can also assist in functioning in very cold weathers. Furthermore, recharging can be done much faster and gassing is virtually removed
