Description
NP, GM-Series VRLA maintenance free batteries, combined with high standards military use maintenance-free lead-acid battery manufacturing technology, used high quality lead as the main raw material, introduced Germany's sunny production technology, the products have good stability, reliability and long service life.
Application
Widely used in aerospace equipment, financial systems data centers, telecommunications mobile computer network center backup power supply, backup power for unattended base station, solar photovoltaic systems, military power, back up power for medical equipment and other important areas.
Technical merits:
●Good airtight performance, no leakage and no acid pollution
●No water loss, no need to add electrolyte
●Special grid design, have excellent discharge performance
●Low impedance and self-discharge, capacity to maintain and storage time can be up to above 12 months at below 20℃.
●C.C.D.S charging and discharging test system to ensure product consistency
●Use high strength engineering plastic as raw material and high-density ultra-fine glass fiber separator, creating top quality batteries
Charging method:
Sealed lead-acid battery capacity and life is governed by the charging voltage, ambient temperature and other parameters, so one important principle for using such kind battery is adopting right charging method. The charging methods depends on the battery running status, usually have two status, are CYCLICUSE (as main power) and FLOATUSE ( as back up power), the following table describes the corresponding charging methods (C for the battery rated capacity)

On the table, the charging voltage is under condition of the 25 ℃ ambient temperature, when the temperature changed greatly, the charging voltage should be adjusted accordingly, the method is:
●Charging voltage reduce 0.003V/cell when ambient temperature rise every 1℃
●Charging voltage rise 0.003V/cell when ambient temperature reduce every 1℃
●If ambient temperature changes more than 10℃, without amendment float charging voltage, may cause the battery damage, it is best to use the battery in the range of 20 ~ 25 ℃ in air-conditioned room.
Recovery charge
In the following circumstances, in need of recovery charge:
● The battery installed but before using
● After the battery discharge
● Battery storage for more than six months;
● Single-cell battery float charging voltage lower than 2.20V, should increase its float charging voltage in short-time; recovery charge voltage 2.30 ~ 2.35V / single cell, the best 2.35V / single cell, recovery charge time 8 to 10 hours (ambient temperature 21 ~ 32 ℃) or 12 to 16 hours (ambient temperature 10 ~ 19 ℃)
If found single-cell battery float charging voltage is very low, it is may caused by the following reasons and deal with as the followings:
●charging voltage is lower than normal to re-adjust the float charging voltage.
●terminals or connecting strips don’t combine close should re-connect.
●load changes frequently and largely, the charger can not automatically adjust in time, can increase float charging voltage 0.02 ~ 0.03V / single cell.
Matters need attention:
● Keep away from heat
● When handling the battery, you must use insulated tools to prevent short circuit.
● The force to tighten the nuts should be uniform not too large, to avoid the damage the pole column, leakage occurs. Different types models and old new batteries can’t use together
