Prostar GPT50-12 front terminal sealed vrla agm battery 12v 50ah

SKU: GPT50-12 Categories: ,

Prostar GPT50-12 front terminal sealed vrla agm battery 12v 50ah uses exclusive IPF technology optimizing power capacity, cell consistancy and long term reliability. Spcae saving Absorbed Glass Mat (AGM) construction allows a -48VDC string to fit in standard 23″ telecom rack systems. The quality standard for long term reliability in all wireleine and wireless carrier application, Prostar has the best reputation in the industry as the design life battery technology leader.

Front Terminal series batteries are designed with a narrow profile and front mounted terminals allowing them to fit into compact spaces that standard batteries cannot.In addition, Prostar front terminal batteries can be layed flat and placed in non ventilated areas, providing an even greater amount of options for fitting your batteries.

Features of Front Terminal Battery

1. Sealed/Maintenance-free

Absorbent Glass Mat (AGM) technology ensures efficient gas recombination up to 99% and freedom from electrolyte maintenance. During the expected float service life of Prostar batteries, no need to check the specific gravity of the electrolyte or add water.

Prostar sealed lead acid battery 12v 50ah can be operated in virtually any orientation without the loss of capacity or electrolyte leakage. However, upside down operation is not recommended.

2. Long Float Service Life

Front terminal battery can be used over 8 years in float using at 25C temperature with a unique corrosion-resistant grid alloy.

3. High Energy Density

Front terminal telecom battery 12v 50ah offers high reliability and delivers superior performance while occupying less space and increasing energy density.

4. Deep Discharge Recovery

Special separators, advanced plate composition and a carefully balanced electrolyte system ensure that the battery has the ability to recover from excessively deep discharge.

5. Economical

The high watt-hour per dollar value is made possible by the materials used in a sealed lead-acid battery; they are readily available and low in cost.

6. Easy Handling

No special handling precautions or shipping containers, surface or air, are required due to the leak-proof construction.

7. Compact

Prostar batteries utilize state of the art design, high grade materials, and a carefully controlled plate-making process to provide excellent output per cell. The high energy density results in superior power/volume and power/weight ratios.

8. Low Pressure Valve Regulators

All batteries feature a series of low pressure one-way relief valves. These valves safely release any excessive accumulation of gas inside the battery and then reseal.

9. High Discharge Rate

Low internal resistance allows discharge currents of up to 10 times the rated capacity of the battery. Relatively small batteries may thus be specified in applications requiring high peak currents.

10. Rugged Construction

The high impact resistant battery case is made of nonconductive ABS plastic. The case materials impart great resistance to shock, vibration, chemicals and heat.

Battery Construction

Battery Construction


Depending on the model, batteries come either with AMP Faston type terminals made of tin plated brass, post type terminals of the same composition with threaded nut and bolt hardware, or heavy duty flag terminals made of lead alloy.


Immobilized dilute sulfuric acid: H2S04.

Leakproof Design & Operational Safety

The leak proof construction of Prostar batteries has ensured that our batteries have been approved for shipment by air.

Plates (electrodes)

Prostar utilizes the latest technology and equipment to cast grids from a lead-calcium alloy free of antimony. The small amount of calcium and tin in the grid alloy imparts strength to the plate and guarantees durability even in extensive cycle service. Lead dioxide paste is added to the grid to form the electrically active material.

Relief valve

In case of excessive gas pressure build-up inside the battery, the relief valve will open and relieve the pressure. The one-way valve

not only ensures that no air gets into the battery where the oxygen would react with the plates causing internal discharge, but also represents an important safety device in the event of excessive overcharge.

Vent release pressure is between 2-6 psi; the seal ring material is neoprene rubber.

Leakproof Design & Operational Safety

The leak proof construction of Prostar batteries has ensured that our batteries have been approved for shipment by air.


Case and lid material is ABS, high impact, resin with high resistance to chemicals and flammability. Case and cover are made of non-conductive ABS plastic.

This case has molded-in dividers for each 2 volt cell.


Prostar battery separators are made of non-woven glass fiber cloth with high heat and oxidation resistance. The material further offers superior electrolyte absorption and retaining ability, as well as excellent ion conductivity.

Case Sealing

Depending on the model the case sealing is ultrasonic, epoxy or heat seal.
