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


We carry out technical improvements lead-acid Maintenance Free battery based on the introduction of created new maintenance-free 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-regulated .sealed and glass mat is utilized .acid is trapped inside . so refilling is not needed and is leak proof.


NO Memory Effect


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


No memory effect 


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


Low self discharge


The self –discharge rate for TOYO SLA . Maintenance Free battery is about 2-3% per month at room .temperature compared with 20-30% for other common Maintenance Free battery systems .


Longer service life


Utilized thick and massive calcium grate ensure that TOYO SLA Maintenance Free battery has a longer service life over 15years .


High discharge rate .


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


Wide operation temperature range


TOYO VRLA Maintenance Free 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 .

Maintenance Free battery 

Battery Structure


Material of construction 


Positive plates

Positive plates are plate electrodes of which a grid frame of lead-tin-calcium alloy holds lead dioxides as the active material.

Retain sufficient capacity. Maintain capacity performance for long period of time (long life performance). Minimize self-discharge.

Negative plates 

Negative plates are plate electrodes of which a grid frame of lead-tin-calcium alloy holds spongy lead as the active material.

Retain sufficient capacity. 
Maintain capacity performance for long period of time (long life performance). Minimize self-discharge.


The advanced micro porous Absorbed Glass Mat (AGM) or PVC separators retain electrolyte and prevent shorting between positive and negative plates. Separators adopt a non-woven fabric of fine glass fibers, which is chemically stable in the diluted sulfuric acid electrolyte. Being highly porous, separators retain electrolyte for the reaction of active materials in the plates.

Prevents short circuit between positive and negative plates. 
Retains electrolyte.
Prevents active material fall by pressing plate surfaces.


The GEL Electrolyte is used as the medium for conducting ions in the electro-chemical reaction in the Maintenance Free battery. 

The GEL Electrolyte is used as the medium for conducting ions in the electro-chemical reaction in the Maintenance Free battery. 

Container & Cover

Materials of the body and cover of the Maintenance Free battery case are ABS resins, unless otherwise specified 

Accommodates plate group consisting of positive and negative plates and separators. 
Retains sufficient mechanical strength to withstand Maintenance Free battery internal pressure.

Safety valve 

Synthetic rubber with excellent acid resistance and little deterioration by aging. In cap shape. The valve is comprised of a one-way valve made of material such as neoprene.

Releases gas if cell internal pressure rises abnormally high and normalizes internal pressure. Prevents ingress of oxygen. 

Solar Maintenance Free batteries are an intricate component for off-grid electrical systems such as solar, wind, and mini hydroelectric systems.

All these systems produce DC electrical which must be stored so that it may be used at a later time. In order to do this at the present time we use deep cycle Maintenance Free batteries.

Deep cycle Maintenance Free batteries are used because they have the ability to be recycled many times. This means that they can go from being charged to being discharged to 50% numerous times without damaging the Maintenance Free batteries unlike that of other Maintenance Free batteries such as cranking Maintenance Free batteries which are used to start vehicles.

The innovative Gel Technology does not only combines the advantages of lower internal resistance of deep cycle Maintenance Free battery , but also do have much much better thermal stability and longer cyclic life .


The terminal is in the structure of tin electrodeposited copper terminal, which is favorable for discharging Maintenance Free battery with large current and is favorable for the reliability of connection between Maintenance Free batteries.  The terminal is sealed through fusion welding and second seal of resin sealant, and the seal reliability is high.

Process & QC

QC system :
1. original material inspection : 99.9999% pure lead .

2. ABS Maintenance Free battery case testing :  Anti - impact / Prevent Burst.

3. Meaure each Maintenance Free battery acid  electrolyte weight - Ensure the consistency of every Maintenance Free battery

4. Charing & discharge testing : deep cycle working

5. Each Maintenance Free battery inspection Before Shipping : Guarantee 100% pass rate.
