-3mV/ /cell 25 As the average ambient temperature rises charging voltage should be reduced to prevent overcharge. Accordingly the recommended compensation factor is -3mV/ /cell at 25 of standard centre point.

Cyclic Charging

As the average ambient temperature rises charging voltage should be reduced to prevent overcharge. Accordingly the recommended compensation factor is -4mV/ /cell at 25 of standard centre point.

Caution: Should set appropriate charging time in or der to avoid excess over charging that can result in the damage of the batteries.

6.9 Eechanical strength

100mm 12V

Drop battery 2 times from a 100mm height onto harden, flat concrete floor in terminal upward direction. Read the voltage and make visual inspection. Battery should no extreme damage and no electrolyte leakage, battery voltage should 12V or more.

7. Installation Conditions

7.1

Storage container for rechargeable battery must not be of sealed and air tight construction; the container must be equipped with appropriate ventilation system such as ventilation holes leading to the outside and so on.

7.2

The following applies to using a rechargeable battery inside a metallic storage box: to prevent the rechargeable battery from leaking fluid due to a breakage in the electrolytic cell, thus forming a leak circuit between the battery and the storage box (or fixed frame), install between these two items a heat and acid resistant insulating sheet (or tray) that will not be damaged by periodic stress. Alternatively, place the rechargeable battery inside an insulating bag but not to be sealed. For the above described insulation material, do not use any material that can be stained with grease, or that can have organic substance oozing out of itself.

7.3

Do not allow the rechargeable battery to come into contact with vinyl tape containing plasticizer, insulation sheet, solvent, or grease.

7.4 5mm 10mm TRS 10mm

When connect battery over 2 rows, to keep good heat emission, distance between each row should be 5mm 10mm. if use thermal switch(TRS) or temperature sensor, distance between each row should be over 10mm.

8. Caution

8.1

Please re-charge the battery rightly after discharge. If battery is over-discharged, please immediately re-charge the battery as well.

8.2

It would be damage on batteries and equipments if using batteries together with different capacity, different lot number, or from different manufacturer. Please contact us if you use in aforesaid way.

8.3

While parallel connection, please consider to keep each parallel group current average, please avoid parallel connection more than 3 groups.

8.4

While cyclic charging, parallel connection maybe will lead battery life shorten or damage, please avoid. If need, please contact us.
