FirstPower Gel ( Gelled Electrolyte ) Battery

1. Introduction

The FirstPower gel battery uses the sealed gel technology and is designed for high reliable, maintenance-free power for renewable energy applications. Depending on the advantage gel technology, optimum grid and plate design, the FirstPower gel battery offers highest power and reliability for your equipments.

2. Features & Benefits

  • Gelled electrolyte By the high-tech gelled electrolyte, gel battery is completely leakproof and spillproof for easy installation in virtually any position even under water. It eliminates ultra deep discharge and acid stratification damage.
  • Critical pressure control valve maintains critical internal pressure while safety expelling excess gas generated during overcharging, for longer battery life. 100% tested for highest performance.
  • Brushed plate lugs provide the benefits. Low-resistance straps with outstanding lug-to-knit and eliminate dropped and loose plates that reduce performance and shorten battery life.
  • Heavy-duty plates with high density and deep-cycle oxide active materials, advanced grid alloy for deep cycle use, provide quick recharge ability and superior deep-cycle and float performance in the most demanding applications.
  • Be good at recovery from deep discharge Gel battery has a tight structure and relative supplies of gelled electrolyte, always has some ions left to conduct charge current resulting in the excellent recovery from deep discharge characteristics.
  • Completely maintenance-free use the "recombination" technique to replaces the oxygen and hydrogen normally lost in a met cell. Particularly in deep cycle applications (normally use the wet battery), and offer a really maintenance free battery.
  • Tank formed plates offer optimum computerized formation, additional quality control and improved voltage matching.
  • Premium glass mat separators reduce gassing and improve gel filling and electron flowing, providing more power.
  • Well low temperature performance, even at very low temperature the gelled electrolyte will not be frozen and provide a well performance. Gel battery is well suited to low temperature applications.
  • Superior life. The FirstPower gel battery maintain a long cycle and float life, provide a lowest cost per month or lowest cost per cycle

 

3. Applications

  • Water pumping
  • Wind generation
  • Cathodic protection
  • Communications
  • Solar system
  • Electric powered vehicles
  • Golf cars
  • Commercial deep cycle applications
  • Power plant
  • UPS systems

 

4. Charging

While the FirstPower gel battery will accept a charge extremely well due to its low internal resistance.

For using the sealed design, over-charging will dry out the electrolyte by driving the oxygen and hydrogen out of the battery, through the safety valves. Capacity is reduced and life is shortened If a battery is continually under-charged,
a power robbing layer of sulfate will buildup on the plates. Battery performance is reduce, life is reduced.

So what is important for gel battery that is: charge at least 2.30V/Cell volts but no more than 2.35V/Cell volts at
68 oF(20 oC). Constant current chargers should never be used on gel battery.

Constant charging voltage: Shown is the constant charging voltage in relation to the ambient temperature. The bandwidth shows a tolerance of ±30mV/Cell. This constant voltage is suitable for continuing charging and cyclic operation. In a parallel standby mode it always keeps battery in a fully charged state; in a cyclic mode, it provide for a rapidly recharging and highly cyclic performance.

5. Discharge & cycling ability

Battery discharge capacity and cycle life are depended on the depth of discharge (DOD), and the ambient temperature.

FiretPower gel battery is designed to the "acid limited." This means that the power in the acid is used before the power in the plates. This design prevents the plates from ultra-deep discharges. Ultra-deep discharging is what causes life-shorting plates shedding and accelerates positive grid corrosion which destroy a battery.

Capacity vs. operating temperatures: shown are the changes in capacity for a wider ambient temperature range, giving the available capacity, as a percentage of the rated capacity, at different ambient temperatures, for 3 different load examples, with uninterrupted discharge to the appropriate discharge cut-off voltage.

The values for the upper edge of the curves were obtained from charging at an ambient temperature of +20℃ with a voltage limit to 2.30V/Cell. For the lower edge, charging was carried out at the specified ambient temperature. The curves show the behavior of battery after a number of cycles.
