ESG Log life deep cycle Power system 12V180ah 190ah 200AH 210ah 220ah Front Terminal Solar Gel Storage GEL Battery 

 Why choose us?

 Why choose us?

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.

NO Memory Effect

Some batteries say nickel –cadmium batteries.will become conditioned to provide less power after repetitious short usage discharge .

No memory effect  

Some batteries .say nickel –cadmium batteries will become conditioned to provide less power offer repetitious short usage /discharge

Low self discharge 

The self–discharge rate for ESG 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 ESG SLA battery has a longer service life over 15years .

High discharge rate .

Since the internal resistance is low .the battery can provide high rate of discharge

Wide operation temperature range

ESG SMF battery capacity is rated at 20°C , and will operate from 15°C (5°F)+50°C (122°F)when it is fully

charged Ambient temperature is 20°C.service life will be more efficient under 15°C to gel deep cycle battery for solar street light.r

Technology

Instruction

  \

1. Positive electrode plates

Positive plates are made of lead –calcium alloy with special chemical formula

2. Negative electrode plates

Negative plates are made of lead – chemical formula

3. separator

The glass – fibre separator in ESG SLA battery are made with advanced technology –this high porosity

of the separators retains adequate electrolyte for reaction with active material of the plates .

4.safe valve

The valve system which operate from 1 psi to 6psi (0.07-0.43kg/cm³) is designed to release excess gas and keep the internal pressure within the optimum 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 rupture .once it has opened m it automatically closed in preparation for future excessive increase in pressure.

5. Terminal

Depending on the battery model in MICRO series ,the terminals may be fasten type , bolt –and nut type ,

pressure 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 strut

6.case

For 6v ,8v and 12v batteries ,standard container are manufactured from ABS plastic resin ,It is optional to use flame retardant ABS plastic resin 

Each 6v battery has 3cells .8v battery have 4cells and 12vbattery has 6cells

7.Epoxy

The ABS plastic cover and container are sealed by a special epoxy that is acid resistant .r
