Why choose LFP battery to make car starting battery---For Malaysian market.

# I understand that lead-acid batteries still dominate the Malaysian market, and lithium batteries are still in the early adoption stage.
Malaysia has around 95% fuel vehicles, and lead-acid is still the main choice for car starting batteries.
However, switching from lead-acid to LFP is not just a replacement — it is an upgrade

Malaysia's high-temperature climate, LFP batteries have absolute advantages — they are safer, longer-lasting, and more durable.
Lithium Iron Phosphate (LFP) batteries feature a strong olivine crystal structure, with a thermal runaway temperature as high as 800°C, far higher than that of ternary lithium batteries (200°C) and lead-acid batteries.
In extreme tests such as nail pe*******on, crush, and overcharge, LFP batteries typically only emit smoke without open flame, explosion, or releasing oxygen to support combustion, resulting in an extremely low risk of fire.

-quality lithium iron phosphate (LFP) batteries offer superior overall safety compared to lead-acid batteries under both normal operation and extreme fault conditions, thanks to their high thermal stability, active BMS protection, long service life and leak-free design.

regulations are phasing out lead-acid batteries.

the government tightens environmental and recycling regulations, the cost of lead-acid batteries is rising, making LFP a more compliant and safer choice.

Defects of Lead-Acid Batteries

1. Heavy and bulky
They are much heavier than lithium batteries for the same amount of power.
2. Short cycle life
They can only be recharged around 300–500 times before performance drops badly.
3. Slow charging
Takes a long time to fully charge, and cannot support fast charging.
4. Poor low-temperature performance
Loses a lot of capacity and becomes weak in cold weather.
5. Low energy density
Stores less energy in the same space compared to LFP / lithium batteries.
6. Risk of acid leakage & corrosion
Contains liquid acid that can leak, damage equipment, and cause corrosion.
7. Require maintenance
Some types need checking of water levels and ventilation.
8. Not environmentally friendly
Contains lead and acid, which are toxic and hard to recycle safely.
9. Self-discharge is high
Loses power quickly even when not in use.

Why we should select the LFP car starting battery, not lead acid?

1.Super long life

The cycle life of lead-acid batteries is generally 250 to 300 times, and the cycle life of this lithium iron phosphate battery is about 3,000 times. If the vehicle is parked for a long time without starting, the car battery will be exhausted and the lead-acid battery will be scrapped. However, the lithium iron phosphate battery can still be used normally after charging without affecting its lifespan.

2. Ensure safety

The main component of lithium iron phosphate battery is iron, which is not easy to catch fire and explode just like the main component of lead-acid battery is lead.

3. Improve power and reduce fuel consumption

The internal resistance of the battery is low, the output current is large, the spark plug spark is large, the ignition speed is fast, and the oil is fully burned. Peak horsepower is increased by approximately 4.5%, and peak torque is increased by approximately 3%. Lithium iron phosphate batteries reduce fuel consumption by 5% compared to lead-acid batteries.

4. High energy density
The capacity of lithium iron phosphate of the same volume is 50% greater than that of lead-acid, and the weight of lithium iron phosphate of the same volume is 70% less than that of lead-acid.

5. Good high temperature performance

Lithium iron phosphate electric heating peak can reach 350℃~500℃.

Lithium manganate and lithium cobalt oxide are around 200°C.

The working temperature range of lithium iron phosphate is -20℃~80℃.

The operating temperature range of lead-acid batteries is -20℃~50℃.

6. Reduce vehicle weight

Lithium iron phosphate batteries weigh 70% less than lead-acid batteries. The reduced weight allows the car to accelerate faster and consume less fuel.

7. Improve sound quality

The battery has low internal resistance and high transient output power, which fully meets the stringent requirements for instantaneous high-current power supply when the audio is highly dynamic, making the mid-bass thicker and the treble more transparent.

8. Scientific and environmentally friendly

Lithium iron phosphate batteries do not contain heavy metals and rare metals, are non-toxic, non-polluting, and comply with European RoHS regulations. Used batteries can be recycled, refined and reused.

9. Safe and reliable

Built-in intelligent BMS management system, with multiple protection functions such as overcharge, over-discharge, over-current, over-voltage, over-temperature, overload, short-circuit protection, etc., to avoid battery damage caused by overcharge and over-discharge, and is durable.

Let me continue to introduce our main selling product, 12.8V lithium car starting battery.

What a pity, the below Vedio is not speaking with English, but sometimes, reading is also good ways and habit to make you more understanding about it. Alright!Let' s me get down to the business:

Our LFP car starting battery features combine bluetooth and press button function to lock some electricity in the battery to satisfy your needs of emergency.

When we get off our car and lock the car's door, sometimes, people forget to turn off the battery supply before it.

We can use the electricity volume we set via bluetooth(You can set 20% or 30% freely), once the electricity from the bluetooth we set are used up,there is still some electricity left which we can use it by pressing the emergency button to start our car.

Have locked some electricity volume 2 times through bluetooth and emergency button that have prevented our battery is damaged because of the over discharge.

From the APP on your mobile, we could check how much the electricity of the battery has been consumed and whether the electricity is leakage.

It features "55 seconds delay" after pressing the emergency button, your car must be restarted within this time. So...be quick,discard the slowly action.

Let me go on telling you some secrets about the terminal pole. Positive stands for" + " icon, it is wearing a red color cap now.

Negative stands for" - " icon,it is wearing a blue or black cap now.

Lead pole has a big impedance,we use copper to make the terminal pole which is at high price and good electricity conductivity,low heating rate and impedance,very durable as well.

The positive pole is bigger than the negative pole to avoid uncorrectly install, both of them comply with the standards.

AUG company have prepared a wide range of the battery box /some one call it "housing" according to the your car brand.

Commonly used in the market is 70D23(Japanese cars)57117( American car series)L2400(Volkswagen series,European car series)

I am glad to get you a product list to show you the appearance of outer box when you reaching out to me.

Let's look at the inner structure of the battery box, you can see the cable we used is big and thick,why we use so big cable?

As it can withstand the high current up to 1000A when the electricity go through it.The instantaneous current will reach it.

When read here, I am so grateful for you, and hope you are still keeping your great interest enthusiasm.( And please take a break if neccessary)

Alright, let me continue.....Why AUG car lithium starting battery features" Double protection " How it has been done?"

1: BMS with Blue tooth, operate the function on your mobile APP.
2: BMS with emergency function through press button to achievement.

Look at inside through vedio, the switch we use is a magnetic latching contactor

Magnetic contactor features save electricity, good conductivity, high current through.

The aluminum rows inside are very thick to hold the high current flow.
All cable or collecting lines are in order and fixed with clip, look neat inside.

The capacity of the lithium battery is real as it is produced by AUG company, different with other supplier with virtual mark.

Both circuit and temperature sensor are the best, sure you can see the battery temperature though APP on your mobile.
