12V 9Ah Battery
This is a 12V 9Ah battery, but the key is that it is lithium iron phosphate (LiFePO4) technology. Its core advantages are light weight and ultra-long life. It is specially designed to upgrade and replace the heavy and unsustainable traditional lead-acid battery you may be using now.
This is a 12v 9ah battery f2 terminal, which is the same as many lead-acid batteries, making it convenient for you to directly replace and install.
Compared with the lead-acid battery of the same specification, it is about the same size but almost half the weight. Contact us for more information.
12v 9ah rechargeable battery beneftis
- 6000+ ultra-long charge and discharge cycle life, fewer replacements, saving money in the long run.
- The weight is greatly reduced, which provides a lot of convenience for equipment transportation and flexible performance.
- The voltage is stable, unlike the lead-acid battery which drops quickly, and it can release 99% of the effective power.
- Built-in intelligent BMS provides overcharge, over-discharge, short circuit and high temperature protection, eliminating the potential risks of lead-acid battery leakage and gassing.
- No need to add water and maintain, sealed design, and the material is more environmentally friendly.

12V 9Ah lithium battery replacement and installation
Hongyitai 12.8V 9Ah lithium iron phosphate battery installation is simple, but you need to pay attention to the following points:
Physical size and terminals. This battery is designed according to the standard size of 5.94 * 2.56 * 3.7 inches, and the terminal type is also F2. Generally speaking, as long as the lead-acid battery you originally used is also around 12V 9Ah, the size and terminals match, it is usually no problem to directly replace it physically.
Charger. We do not recommend continuing to use lead-acid battery chargers, because the 13.8V floating charge method is different from that of LFP batteries. This will cause the battery to be undercharged and will also affect the battery’s cycle life.
12V 9Ah lithium battery combination
Not all lithium iron phosphate batteries can be connected in series (to increase voltage) or in parallel (to increase capacity) at will. This mainly depends on the design of the battery protection board (BMS) inside the battery.
You must use new batteries of the same brand, model, capacity, and preferably from the same batch. You must not mix old and new batteries, or different models.
We support up to 16 series, 3.2V * 16 = 51.2V. We support up to 4 parallel, 9Ah * 4 = 36Ah. Please contact us for confirmation before connecting in series or parallel.
12V 9Ah lifepo4 battery applications
Hongyitai 12v 9ah lithium ion battery is very light, has a long life and stable power supply. It is commonly used in scooters, generators, atvs, ups, bikes, security alarm systems, solar energy storage systems, ride-on toys, etc.
FAQs for 12.8V 9Ah Battery
How long the battery lasts (meaning how long it lasts on a single charge) depends entirely on the load of the device you connect it to.
A device that draws less power (e.g. 0.5A) might last closer to 18 hours.
The charging time depends mainly on the output current of the charger you use.
Using a charger with 1A output, it takes about 9-11 hours to fully charge.
Use a lithium iron phosphate battery charger, the recommended charging current is 1.8A - 4.5A, and connect correctly: connect the positive pole (+, usually red) of the charger to the positive pole (+) of the battery, and the negative pole (-, usually black) to the negative pole (-) of the battery. Charge in a well-ventilated, dry environment at room temperature away from flammable materials.
