12V180ah VRLA battery for Sale
The McNair sealed lead acid battery (SLA battery) is leak-proof and maintenance free.
The Superiority of SLA battery is derived from its uniquely efficient oxygen recombination technology .The oxygen evolved from the positive plates diffuses through the micro porous glass fiber mat to the negative plates where it is change back to water by recombination reaction, eliminating the need for water addition .The result is a maintenance free battery
1.No Free Acid
All of the electrolytes are absorbed into the positive plates, negative plates, and the micro porous glass fiber mat. There is no free acid inside the battery, therefore the McNair SLA battery can be mounted in any location.
2.Safe and Sealed
The unique construction and sealing technology ensure that no electrolyte leakage can occur from the terminals or cases of any McNair SLA batteries
3.Maintenance -Free Operation
During the expected service life, there is no need to check the specific gravity of electrolyte or to
add water.No Corrosive Gas Generation
There is no corrosive gas generation during normal usage, as gas generation during over-charge is recombined in a unique "oxygen cycle".
4.Gas Pressure-Venting System
SLA batteries are equipped with a safe, low pressure venting system, which automatically releasing excess gas in the event that gas pressure rises to a level above the normal rate ensuring no excessive build-up of gas in the batteries. Resealing is automatic once the pressure is returned to normal.
5.Long Service Life
The use of heavy-duty lead-calcium alloy grids with anti-corrosive construction enables the McNair SLA Batteries to remain in float service for 3-5 years (6V, 12V series) and above 10 years (2V series), or expect between 250-1000 charge/discharge cycles depending on the average depth of discharge.
6.Long Shelf Life
At an environmental temperature of 25ºC(77oF), the self-discharge rate of SLA batteries is only 3%(approx.) of rated capacity per month. Lower storage temperature enhances shelf life characteristics even further.
7.High Discharge Recovery
Special separators, advanced plate composition, and a carefully balanced electrolyte system have greatly improved the ability of recovering from excessively deep discharge.
8.High Quality and High Reliability
The McNair SLA battery has stable and reliable capacity. It withstands overcharge, over discharge, vibration, and shock. McNair batteries are 100% tested on line for voltage, capacity, and seals.
9.High Power Density
McNair SLA Batteries save installation space, while providing full and reliable power for the equipment, and many have been designed for high power output.
10.Charging Methods
The capacity or life of the SLA batteries is influenced by environmental temperature, charging voltage and other parameters. So charging methods is important to the SLA batteries.
Electrochemical activity in a battery increases as temperature rises and conversely decreases as temperature falls. Therefore, when temperature rises, the charge voltage should be reduced to prevent overcharge, and when temperature falls, the charge voltage should be increased to avoid undercharge. Generally, use of a temperature compensated charger is recommended in order to obtain optimum service life. Charging temperature adjustment as following:
2V battery: U= U0-(t-25) ×0.003 U: actual charging voltage
6V battery: U= U0-(t-25) ×0.01 U: charging voltage at 25ºC(77 OF)
12V battery: U=U0-(t-25) ×0.018 t: temperature
Temperature compensation of charging voltage is not required when using the batteries within 15ºC(59 OF) to 35ºC(95OF) range.

Application
Charging Method | Standby/Backup Use | Main Power use | Refresh Charge During Storage |
Float Charge Operation | Trickle Charge Operation | Cyclic Charge Operation |
Constant Voltage Charging | Regulation range of controlled voltage: 6V batteries: 6.75V to 6.9V 12V batteries: 13.5V to 13.8V Initial current: No limit | Regulation range of controlled voltage: 6V batteries: 7.2V to 7.35V 12V batteries: 14.4V to 14.7V Initial current: 0.3C or less |
The current capacity of charger must be big enough to maintain the specified charging voltage during float. Some safety devices, such as thermostat, fuse and others are recommended to be installed | | | Several of the same model batteries, under the same storage, can be charged in series. Otherwise they should be recharged in separate groups. |
The charge voltage must be regulated precisely. Otherwise, batteries may be overcharged or undercharged. The charge voltage should be adjusted when batteries are used in a wide range of ambient temperature. |
Constant current charge | Not applicable | Charging current: approx. 0.1C Charging time control is strictly recommended because overcharge is more likely to occur. |
Two-steps combination charging | Regulation range of controlled voltage: the fist step: 6V batteries: 7.2V to 7.35V 12V batteries: 14.4V to 14.7V the second step: 6V batteries: 6.75V to 6.9V 12V batteries: 13.5V to 13.8V Initial current: 0.3C or less | | |
Handling Instructions of 12V180ah VRLA battery for Sale:
It is important to avoid overcharge or over discharge, and charge the battery immediately after discharging. When the batteries are stored in the discharged state, they may be had difficulty in recharging due to the increase in the internal resistance.
Charge the batteries, at least once, every six months during storage below 25ºC. The period of this charge must be shortened to half by temperature rising in every 10ºC.
Avoid locating the batteries near a heat-generating device (such as a transformer) or near fire. Do not locate the batteries near a device that may cause sparks, and do not bring fire close the batteries. Keep batteries in a place where the temperature is sufficiently low.
If the batteries are to be used in an enclosed space or in a container, provision should be made for adequate ventilation.
Do not place the batteries in an atmosphere of organic solvent or adhesive materials.
When connecting the batteries, free air space must be provided for each battery. The recommended minimum space between batteries is 5mm to 10mm.
Clean the battery with a piece of wet cloth. Never have the battery splashed of deposited with oils or organic solvents such as gasoline or paint thinner, nor have it cleaned with cloths impregnate with these materials.
Dismantling the battery is not advisable. If sulfuric acid is deposited on skin or clothes, please wash well with sufficient amount of fresh water and obtain immediate medical attention.
Mixed use of batteries with different capacities, histories and or manufactures is liable to cause damage to the battery or the equipment. If this is unavoidable, please consult manufacturer beforehand.
Fasten the batteries securely to protect it from abnormal vibration and shocks during service.
It is advisable to periodically to do check and maintenance.
Measure the total voltage of the batteries during float charge. If the charge equipment provides an irregular readout, be sure to investigate the reason behind any deviations from the specified voltage range.
Check the batteries for any sign of irregularities in appearance. If any damage such as a crack and deformation, or electrolyte leakage is found on the case, cover, etc., the batteries must be replaced with a new one. Also, clean the batteries if these are found dirty due to dirt and dust.
Do not short batteries. Do not attempt to disassemble the batteries. Avoid contact with sulfuric acid leaked from the broken batteries.
