1.Maintenance freeas it is value-regulated .sealed and glass mat is utilized .acid is trapped inside .so refilling is not needed and is leak proof.
2.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 .
3.NO Memory Effect .-some batteries say nickel –cadmium batteries.will become conditioned to provide less power after repetitious short usage /discharge .
4.No memory effect– some batteries .say nickel –cadmium batteries will b3ecome conditional to provide less power offer repetitious short usage /discharge
5.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 .
6.Longer service life –utilized thick and massive calcium grate ensure that HENDA SLA battery has a longer service life over 15years .
7.High discharge rate .since the internal resistance is low .the battery can provide high rate of discharge
8.Wide operation temperature range – HENDA sla battery capacity is rated at 20”C, and will operate from 15”C (5f)+50”(C (122F)when it is fully charged Ambient temperature is 20”C.service life will be more efficient under 15’C to 25”C /
1. Positive electrode plates
Positve plates are made of lead –calcium alloy with special chemical fromula
2. Negative Electode plates
Negative plates are made of lead – ehemical fromula
The glass – fibre separator in HENDA SLA battery are made with advanced technology –this high porosity of the separators retains adequate electrolyte for reaction with active matterial of the plates .
The valve system which operaters from 1 psi to 6psi (0.07-0.43kg/cm3) is designed to relaease excess gas and keep the internal pressure within the optmum range of safety .it protects the negative plates from contamination from oxygen in the air valve are 100%visually inspected during battery production
If the internal pressure is increased to an abnormal level during overcharge ,the safety valve ill be opened to release gas . it thus eliminates the danger of repture .once it has opened m it automatically closed in preparetion for future excessive increase in pressure.
Depending on the battery model in MICRO series ,the terminals may b e fasten rype , bolt –and nut type , pressue contact type ,cable –and connector type or other special types
Terminals of MEDIUM series and MACRO series are threaded –insertion type of bolt –and nuts types
Construction of threaded-insert strud
For 6v ,8v and 12v batteries ,standard container are manufactured from ABS plastic resin (UL94HB),It is optinal to use flame retardant ABS plastic resin (ul94vo)
Each 6v battery has 3cells .8v battery have 4cells and 12vbattery has 6cells
The ABS platic cover and container are sealed by a special expoxy that is acid resistant .
