HENDA models are suitable for a wide range of general applications including security and u.p.s In meeting the expanding power supply requirements of telecommunication and power systems .HENDA is developed Henda including medium series (12V) and MACRO series (2v)is rated .10hour discharge rate and has long designed lifetime of 5-10years standby use with no virtual maintenance requited it is suitable for much powerful applications like big U.P.S . telecommunication. System and solar system . micro series ranged from 6v 1.3AH to 6V12AH and 12V.0.8AH to 12V 28AH. MEDIUM series ranges from .12V 33AH to 12V .200AH. MACRO .series ranges from 2V 100AH to 2V .3000AH . As a result of our continuous contributions to .R&D.more new models will be added Battery properties HENDA sealed lead acid battery (SLA )is an advanced and economic rechargeable battery it has several properties differ from other types of batteries Maintenance free as it is value-regulated .sealed and glass mat is utilized .acid is trapped inside .so refilling is not needed and is leak proof. High power to-weight ratio HENDA SLA batteries can provide much power in comparison to its Weight .for example 6v and 12v MICRO series battery capacity range of room 0.8ah .to 28ah. Weight range only from 0.3to 9.5kgs . No memory effect some batteries .say nickel cadmium batteries will b3ecome conditional to provide less power offer repetitious short usage /discharge Low self discharge the self discharge rate for HENDA SLA . battery is about 2-3% per month at room .temperature compared with 20-30% for other common battery systems . Longer service life utilized thick and massive calcium grate ensure that HENDA SLA battery has a longer service lifePHYSICAL SPECIFICATION Nominal voltage Nominal capacity (20HR) 6V 4AHDimensions length Width Container height standard cover Total Height 134+- 1mm. 34+-1mm 60+-2mm 66+- 2mm Weight Approx0.6kg Terminal / standard cover . f1-faston tab no.187e ELECTRICAL SPECIFICATION capacity 20hour rate (0.20A) 10 hour rate (3.6A) 5hour rate (3.2A) 1hour rate (2.4A) 3.2AH 3.0AH 2.7AH 1.92AH It is recommended to use constant-voltage charge and recharge immediately after use Capacity affected By temperature 40C(104F) 25C(77F) 0C (32F) 105% 100% 85%Constant Voltage charge Cycle Initial charging current less than 1.32AVoltage 7.2v-7.5v at 25C (77F)Temperature coefficient -15AMV/C Internal resistance Fully charged battery b25C .77f) Standby Valtage 6.75-6.90v.initial charging current less than 0.5AMV/C.
