Lead-acid battery consists of : positive plate, negative plate, electrolyte, AGM separator, battery slot, battery cover, pole, pouring cap and other components.

We carry out technical improvements lead-acid battery based on the introduction of created new maintenance-free batteries .

They can use for UPS float standby systems, also can meet the solar energy systems of daily charge and discharge all the time, and deep cycle work requirements .

Maintenance free

As it is value-regated .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 offer repetitious short usage /discharge

Low self discharge

The self –discharge rate for TOYO 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 TOYO 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 VRLA battery capacity is rated at 20 °C , and will operate from 15°C (5f)+50°(C (122F)when it is fly

charged Ambient temperature is 20°C.service life will be more efficient under 15’C to 25”C .

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 matterial of the plates .

4.safe valve

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

6v12v 4ah 7ah 8ah 9ah 12ah 20hr tools small rechargeable batteries

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.

5. Terminal

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

3.case

For 6v ,8v and 12v batteries ,standard container are manufactured from ABS plastic resin (94HB),It is optinal to use flame retardant ABS plastic resin (94vo)

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

7Epoxy

The ABS platic cover and container are sealed by a special expoxy that is acid resistant .
