1 Nikel Cadmium Battery Introdution Ò STLONG Batteries are manufatured in basi range to math speifi operating ondition and providing different performane harateristi. Our Batteries will ombine maximum performane with minimum maintenane and optimum life. The nikel admium batteries use relatively expensive material they are arefully designed to obtain maximum utilization from them. Thus the nikel admium batteries may be more expensive in first ost than the lead aid batteries and onsiderably less expensive in the long time. Benefits -Exellent high rate disharge performane. -Vert long life -Wide operating temperature range -Lowest self disharge -Resistane mehanial and eletrial abuse -Low internal resistane -Absolute reliability THONG FATT JAYA MACHINERY HARDWARE SDN. BHD. ( V) Due to the poliy of onstant researh and development, speifiations may hange without prior notie. Copyright Ó Thong Fatt Jaya Mahinery Hardware Sdn.

4 Charging The most ommon form of harging for stationary batteries is modified onstant voltage, usually with urrent limitation to C/5 or C/10. The battery is permanently onneted to the harger whih applies a onstant voltage aross the battery terminals. Reommended harging voltage The following per-ell harge voltage are reommended. Cell type IEC type Floating harge Equalizing harge GNC KXP GNH KHP GNM KMP GNL KLP Initial harging The whole harge should preferable be arried out at onstant urrent. The harging time is inversely proportional to be urrent whih is set by the urrent limit of the harging equipment. Reommended rates for the first harging: 0.2C5A for 10 hours 0.1C5A for 20 hours Disharging Curves Nominal voltage 1.2V/Cell.4.

Example A STLONG battery is required to maintain an inverter load of 50KA at 0.8 power fator for a bak up time of 30 minutes at normal temperature. The D.C. voltage to the inverter operates within the limit of 265 voltage with the battery on float harge to a minimum of 202 voltage at end of bak up time. The inverter has an 85% effiieny. -Number of Cells (at reommended float of 1.44v.p..) = ells -Minimum ell voltage = voltage per ell -Maximum Battery Current = (Inverter load in KVA x power fator) ( min. ell voltage x number of ells x inv. effiieny) 50KVA x 0.8 =232.5Amps 1.10 x184 x 0.85 we shall hoose the battery with apaity equal or just above.
