12V 30Ah Battery
Traditional 12V 30Ah lead-acid batteries are bulky and have a short lifespan. They need to be replaced after 2-3 years of use. They also require maintenance, watering, and possible corrosion of the terminals. Today’s 12V 30Ah lithium iron phosphate battery is an ideal choice for you to replace old batteries or pursue better performance. Its service life is 5-10 times that of lead-acid and it is completely maintenance-free. Get our best factory price today.

Hongyitai Batery Performance Curve
12.8V 30Ah lithium battery charge & discharge curve
On the left is the discharge curve, showing the voltage change at different discharge rates.
When fully charged: the battery voltage is about 14.6V.
Discharge process:
- 100% charge: about 12.8V
- 75% charge: about 12.5V
- 50% charge: about 12.2V
- 25% charge: about 11.8V
- 0% charge (discharge cut-off voltage): usually around 10.5V.
Why choose 12V 30Ah LiFePO4 battery
It weighs only about 4Kg. With the same 30Ah, it is at least half lighter than the traditional lead-acid battery, or even more. If used on your motorcycle or kayak, the control is more flexible.
Ultra-long standby time and long life. Our lithium iron phosphate battery has a cycle life of more than 6,000 times, and can be used for more than 10 years without any problems. In the long run, it is definitely a more cost-effective and worry-free choice.
100% actual usable capacity. The nominal capacity is 30Ah, it can safely discharge 80% or even 100% of the power. It allows your devices to run longer.
12.8V stable voltage output. Unlike lead-acid batteries that lose power at the end of life, our 12.8V 30Ah LFP battery can keep your device running stable and powerful from start to finish.
3C rate charging speed. Its charging efficiency is very high, and with a suitable charger, the charging time can be much shorter than lead-acid.
Low self-discharge rate. If your device is used seasonally, such as a motorcycle stored in the winter, or a lawn mower, lead-acid batteries are prone to loss of power over time. Lithium iron phosphate batteries also have little power loss after a few months.
12V 30Ah lithium ion battery common applications
12v 30ah rechargeable battery has a good balance between size and performance, and it is widely used in, for example, motorcycle, ride on mower, electric wheelchair, trolling motor, RV, camping, and marine.
12V 30Ah lead-acid battery to LiFePO4 replacement guide
Replacing your old lead-acid battery with this new lithium iron phosphate battery is a hassle-free process. In most cases, the replacement process is pretty simple and is similar to replacing a normal battery.
The most intuitive thing is that the new 12.8V 30Ah LFP battery has the same size as the old battery. Another thing is the type and location of the terminal. Our current one is the M5 connector.
Secondly, is the power large enough? Our 12V 30Ah lithium iron phosphate battery is more than enough for most applications, such as starting a motorcycle and powering equipment, and it even feels more powerful when starting.
What we recommend most is to use a charger designed specifically for lithium iron phosphate batteries instead of a lead-acid battery charger.
Most newer vehicles now have charging systems (generators and regulators) that are compatible with lithium iron phosphate batteries.
Installation process: When connecting a new battery, always connect the positive terminal (red, +) first, then the negative terminal (black, -). When removing an old battery, the order is exactly the opposite: first remove the negative terminal (black, -), then the positive terminal (red, +). Remember this order and the operation will be safe.
Charging & Maintaining 12V 30Ah LiFePO4 Battery
After replacing the 12.8V 30Ah LFP battery, daily charging and maintenance are actually much easier than lead-acid batteries. The following are the specific charging and maintenance steps:
The most important thing is the charger. Use a charger designed for lithium iron phosphate (LiFePO4) batteries.
Generally speaking, we recommend a charging current of about 10A. It is not the faster the better, nor the slower the better.
It does not require trickle charging like lead-acid batteries. Lithium iron phosphate batteries have no memory effect and do not require floating charging to maintain their charge.
Try not to use or charge the device in extremely hot or cold environments for a long time.
This is one of the great attractions of lithium iron phosphate. You no longer need to regularly check and add distilled water like some lead-acid batteries.
Keep the battery case clean and do not allow dust and dirt to accumulate; check regularly to see if the terminals are still tight and not loose.
For long-term storage, it is recommended that you charge the battery to 50% to 80%, then remove or disconnect it from the device and place it in a cool, dry place.
12.8V 30Ah LFP battery FAQs
It is highly not recommended and it is best not to use it. Because their charging methods (voltage, process) are completely different. Using a lead-acid charger may not fully charge the battery, seriously shorten the battery life, or even damage the battery or bring safety risks.
All batteries will be affected in low temperatures. However, lithium iron phosphate batteries usually perform better than lead acid batteries in winter, with less capacity loss and more stable voltage. However, do not charge the battery below 0°C.
Yes, the initial purchase price is indeed higher. But the key is the long-term value: LiFePO4 has a service life several times that of lead-acid, weighs only 1/3, has a higher actual usable capacity, and requires no maintenance at all. So, although the initial investment is large, in the long run (considering the number of replacements and the trouble saved), it is often more cost-effective and less troublesome.
