Low voltage floating charge without the need of equalizing charge: 2.23V/cell·25C floating charge at constant voltage, without the need of equalizing charge.
Ten-hour-rate capacity can be reached 100% for the first cycle.
One-hour-rate capacity coefficient is 0.55, final voltage is 1.75V.
Super performance of charge reception.
Self-discharge less than 3% for 28 days storage period at normal temperature.
The pressure of opening and closing valves can be adjusted precisely.
No changes occur on the pressure of the opening and closing valves even after long-time use.
The acid filter can prevent liquid leakage and explosion of batteries.
The terminals and the connect bars are shielded by top covers to prevent accidental short circuit.
The heat sealing structure and resin sealing structure with German resin are reliable.

Check tile mount of batlerics and accessories according to the packing list in the box after unpacking the balteries. Please contract with Post Sales Service Center immediately if there is a lack of batteries or accessories.
Please clean and polish the terminal by brush made of steel wires so than t the resistor of the connector to be lowest before connecting.
All batteries leave the factory wilh electric charge. Prohibit short circuit, and mount by isolative tools to avid an electrical shock during the process of mounting.
Afler finishing connection of the batteries group, check the total voltage of hallery unit and putting of the poles to prevent from reversing the pole.
Disconnect batteries and power supply to prevent the batteries over-discharging seriously even discarding as useless if dell not power on immediately after finishing connection the batteries group.
Check the fastening screws for connecting batteries or output terminal to prevent froml false connection resulting the connection voltage over drop even burning batteries at higher current.
The charging equipment has the capacily to restrict the currenl at constant voltage, with regulalor precision reaching +1% when charging.

The service life at ambient temperature i.e.15-25C is longer (coslight battery can work at – 40 -50C).
The charge equipment can charge at constant voltage with an accuracy of 1%.
Coslight batteries can be installed horizontally or vertically.

If it exceeds (2.24+0~m ) x nv/cell * 25C.(n refer to the number of celles )the total floating charge voltage should be adjusted or the batteries' life will be adversely affected.
The floating charge voltage of single cell should be checked once a month and the records need making carefully. If the differential of floating charge voltage of single cell exceeds 0.05V/cell after it is used for six months, please contact the manufacturer.
The joint parts should be checked once a year. The loosed connection should be deal with as soon as possible.
The longer service life can be achieved if the balteries are used at the ambient temperature of 15~C~25OC, GFM series of batteries can work under the condition of -40C-50C.
Neither Over discharge (discharge voltage lower than final voltage) nor over charge(charge voltage higher than floaling charge for a long time)should be allowed. The batteries should be charged immediately after their discharge or the batteries' life will be adversely affected.
Time, voltage, current and temperature should be recorded at every time of discharge.
Not organic solvent but the soap water is permitted to clean the surface of the batteries. The dry cloth easily producing electrostatic should be avoided.
If the batteries need to be stored, please disconnect the connection among the charge equipment and the loads. The surrounding should be kept cool, dry and ventilated.

Be careful to avoid short circuit of batteries during their transportation and installation, as they have been charged before leaving the factory.
Avoid bumping and humidity during transport, load and unload the batteries.
If the battery needs to be stored, the place for storage should be cool, dry and ventilated.
