1.1 Nonspillable

The ELITE VRLA battery uses an absorbed electrolyte system. All of the electrolyte is absorbed into the positive plates, negative plates, and the separators. Coupled with the use of special sealing epoxies, and long sealing paths for posts, ELITE VRLA batteries have exceptional leak resistance, and can be used in any position.

1.2 Sealed and Maintenance-free Operation

There is no corrosive gas generation during normal use and no need to check the specific gravity of the electrolyte or to add water during the service life.

1.3 High Quality and High Reliability

The ELITE VRLA battery has stable and reliable capacity. The battery can withstand overcharge, over discharge, vibration, and shock. To assure this high quality and reliability, the batteries are 100% tested on production line for voltage, capacity, seals and the safety valve are 100% visually inspected before the final assembly process.

1.4 Exceptional Deep Discharge Recovery

ELITE batteries have exceptional deep discharge recovery and charge acceptance, even after deep or prolonged discharge.

1.5 Low Self-discharge

Because of the use of lead calcium grids alloy and highly purity materials, ELITE VRLA battery can be stored long periods of time without recharge. The rate of ELITE VRLA battery self-discharge on open circuit is less than 2% per month at 20oC/68oF to 25oC/77oF.

1.6 Long Service Life

The ELITE VRLA battery has long life in standby or cyclic service.

1.7 Solid Copper Terminals

Ensures highest current carrying capability.

1.8 Tank-formed Plates

The initial capacity will be 100% and optimize cell voltage balance, due to the tank formation of the plates.

1.9 Computer-aided Design and Manufacturing

Ensures quality products through control of processes and standards.

1.10 UL and CE Recognized.

UL approval, file No. MH28204
CE approval, file No. G2M20201-0102-E-16

2 Battery Life

Battery life depends on a number of key factors. These include:
Operating temperature of the battery;
Method of charging utilized;
Actual use of the product i.e.: standby or cycle service etc.

2.1 Cyclic Life

Giving due consideration to the above factors, the actual life of a battery in cycle service is dependent on the depth of discharge of each cycle. The greater the depth of discharge of each cycle, the less the number of cycles available from the battery.

2.2 Standby Life>

The estimated life under float service of ELITE HR type is 10 years at 20oC/68oF. The float service life is affected by the factors listed above and the number of discharging, the depth of discharging the battery suffers during its life time. The more discharges suffered and the deeper the discharges, the shorter the battery life. The higher the temperature, the shorter the battery life. If the battery temperature remains at an elevated level for an extended period of time, the expected life is reduced by 50% for each 8 to 10oC of constant temperature above 20oC/68oF.

3 Battery Capacity Selection

The capacity of a cell/battery is the amount of charge available expressed in Ampere-hours (Ah) if know the discharging current(power) and the discharging time.
The individual battery model specification sheet can be used to determine the minimum battery size
The battery life(cycle service life or floating service life) should be considered for final battery capacity selection.
