Long Life Gel Battery

BLG2 battery is long life Gel electrolyte battery with designed 12 years life in standby service, or more than 400 cycle life at 50% DOD in deep cycle service.

NPL series batteries are highly efficient and long life gel cell VRLA, AGM (Absorbent Glass Mat) separator maintenance free battery with lead-calcium alloy plate, 

which provides longer standby life performance, extra durability and lifespan.

Voltage : 2V

Capacity : 200AH ~ 3000AH

Application : UPS / Telecom / Base station

Maintenance free

When battery is charging, hydrogen would be absorbed and reversed to electrolyte by plates. It doesn't need to refill water and balanced charge, 

which makes maintenance free.

Flexible installation

AGM separator keep electrolyte absorbed in glass mat and still. Battery can be used or positioned in any orientation.

Longer lifespan in extreme weather

Gel cell electrolyte prevent electrolyte being evaporated in high temperature or being frozen in low temperature, which keep battery in high performance 

in extreme weather.

Extremely safe

When excessive gas production by inappropriate charging occurs, safety valves will automatically emit the gas to prevent battery cracked.

Long standby life, Better cycle performance

Anti-corrosion lead-calcium alloy plate provides longer float charging life. AGM separator can trap electrolyte and prevent active materials on positive plate 

dropping at the same time. Moreover, it gives better deep discharge cycle performance.

Longer shelf life

Special lead-calcium alloy plates make lower self-discharge for longer shelf life.

High rate performance

Low inner resistance allows higher discharging and charging current for better performance in high rate application

Deep-Cycle GEL Battery 

BRAVA's deep-cycle gel batteries are sealed, maintenance-free batteries that deliver superior power in demanding renewable

energy applications. Engineered for rugged durability, outstanding performance and long battery life, BRAVA's deep-cycle

gel batteries feature a number of important design characteristics that provide significant advantages over competing

gel products. The gelled electrolyte is a proprietary formulation that delivers consistent performance and dramatically

extends the battery’s cycle life. Lead alloy grids provide longer shelf life and superior corrosion resistance as well as deliver more concentrated energy to the terminals. 

Its premium grade, double-insulated separators allow maximum charge flow

between the plates for optimum performance.

With a long service life and durable design, gel batteries are at the top end of battery design. The standard gel battery shares many properties

 with AGM deep cycle batteries while the 'tubular' gel battery is more commonly used in large scale, non-portable battery banks.

Both types of gel battery consist of a ‘gelified’ electrolyte that sits between lead plates, making them non-spilling and safe to place on their side. 

This sealed design also reduces the risk of electrolyte evaporation often encountered in traditional wet cell batteries and makes gel batteries highly resistant

 to vibration. It also decreases internal resistance, giving the battery higher charge and discharge capabilities.

Front Terminal GEL Battery

Front Terminal GEL batteries are designed to meet the requirements of heavy duty applications in high temperature. This series is highly suited 

for telecommunications and renewable energy systems where reliability and performance are the priority.

These batteries benefit from an optimized gelled electrolyte which offers a long float life and deep cycle life. These batteries offer easy & fast installation 

and are maintenance free.

The features and advantages are as follows:

Floating charge design life is 15 years

Wide range of service temperature:-15°C ~ 60°C

Nanometer colloid electrolyte is adopted, without electrolyte stratification

Longer cycle life

The front terminal colloidal battery is 30% lower than AGM battery, which is more suitable for high temperature floating charging applications 

and is less likely to lose control of heat

High tin alloy and thick plate design

Lower self-discharge (service life up to 9 months at 20°C)

Long Life AGM Battery

Stationary 2V AGM Batteries Serials are mainly big capacity batteries with voltage of 2V. It use advanced micro porous absorbed glass matt 

separator – minimizes diffusion of oxygen into the separator, reducing float charge current which suppressed the corrosion rate of 

the positive grid and extends the life of the battery.

Battery Features

long life AGM VRLA battery is specially designed on the base of European dwarf form standard structure. It features streamline design and elegant appearance;

Thicker and extended plate can ensure self absorption, thus effectively prolonging service life of the storage battery;

The valve regulated lead acid battery comes with special design that allows almost no reduction of electrolyte volume in use and no addition of water in service life;

AGM Battery / AGM Deep Cycle Battery

Starting, Lighting, Ignition (SLI) - Starter Batteries

These batteries deliver a large burst of power for a short time as needed for normal engine starting. The battery is then recharged by the alternator. Unlike a deep-cycle battery, starting batteries are not designed to withstand multiple discharge/recharge cycles, and draining it can significantly shorten its life.


Deep-Cycle Batteries

These batteries are designed to provide a steady amount of current over a long period of time. Deep-cycle batteries can be repeatedly discharged and recharged without causing damage or shortening their life. They are well suited to powering numerous electronics and plug-in accessories, or other applications that place high demands on them such as marine.

Some deep-cycle batteries can be used for engine starting as well (these are sometimes referred to as dual-purpose), but be sure to check the CCA rating to ensure the battery has sufficient starting power.



Deep cycle batteries provide sustained energy, making them ideal for certain applications that require more than a quick start. Some of the most common uses for deep cycle batteries include:

Marine applications
Recreational vehicles
Materials handling, including forklifts
Golf carts
Off-grid renewable energy

For some applications, particularly marine uses, hybrid batteries are another solution. A hybrid marine battery can offer both a starter burst and sustained power for marine applications, but tends to have a shorter lifespan than a battery with a dedicated role



Even among deep cycle batteries with similar functionality, there are different types. The two most common types of deep cycle batteries are flooded deep cycle batteries and sealed or “maintenance-free” deep cycle batteries.


Flooded deep cycle batteries require regular monitoring. When the electrolyte levels are low in this type of battery, the user must refill the battery appropriately to maintain performance.


“Maintenance-free” batteries, which are also called “Sealed” or “Valve Regulated Lead Acid” batteries are sealed and do not require watering, although regular inspection is still recommended. 

As a consumer or a battery dealer, it is essential to understand the different functions of battery types. While the deep cycle battery distinction may not mean much to the average person, the more you know the better you can make effective power storage choices for all your needs.


A deep cycle battery is a battery that is designed to produce steady power output over an extended period of time, discharging the battery significantly, at which point it must be recharged to complete the cycle. By contrast, a regular car battery is designed to provide a momentary burst of energy, typically enough to get your car started, before handing off power production to the alternator. In this case, the battery is not designed to be cycled because it should be kept fully charged at all times.



A deep cycle battery is rated by the number of complete cycles that it will provide, as well as the depth of discharge that is allowable, and the amount of amperage that it will produce steadily. For instance, a deep cycle battery listing will tell you that it produces 75 Amp-Hours for a period of 20 hours, and is rated for 1000 full cycles at 80% depth of discharge. These numbers tell you how long the battery will last, how far you should be discharging the battery, how long you can expect to go before you need a battery replacement, and what kind of power you can expect in the meantime. With an ignition lead acid battery, the rating that matters most is the cold cranking amps (CCA), which only tells you how much power the battery can produce in a single burst at 32 degrees.
