Voltage Requirements: Electric bicycles and motorcycles often require higher voltages (24V, 36V, 48V, or 72V), achieved by connecting multiple 12V 20Ah batteries in series. For example, a 48V system uses four 12V 20Ah batteries.
Fitment Check: Ensure the battery’s dimensions (180 × 76 × 170 mm) and terminal type (8.8-M5, copper) match the vehicle’s battery compartment and wiring.
Model-Specific Verification: Many brands have transitioned to lithium-ion batteries in newer models. The 12V 20Ah SLA battery is more common in older models, budget lines, or mobility scooters.
Aftermarket Compatibility: Brands like TDPRO and WPHMOTO provide 12V 20Ah SLA batteries for generic or custom electric bikes, scooters, ATVs, and go-karts, indicating broad applicability.

To confirm compatibility, check your vehicle’s specifications for battery type, voltage, capacity, and dimensions. If you have a specific model in mind, provide its details, and we can help verify compatibility further!

Before using the product, please read the user manual carefully.
For brand-new batteries or those that have been unused for a long time, please use them before charging. During the first five uses, charge the battery only after the power has been reduced by more than 70%.
Make sure the battery is installed securely to avoid damage from vibrations while riding.
Each time you ride, avoid draining the battery completely. Develop the habit of charging in time, keeping the battery as close to full as possible.
Charging: In winter, perform a float charge for 4 hours; in summer, 2 hours. It’s best to use a high-quality charger with a pulse function that matches the battery. Do not charge in direct sunlight or in a hot, enclosed, and poorly ventilated space.
If your rides usually consume less than 70% of the battery’s capacity, perform a deep discharge (over 70%) at least once a month.
Always use the original charger that came with the battery. Do not replace the charger at will, and do not remove the speed limiter on the controller, as these actions can shorten the battery’s lifespan.
Regularly check the battery’s connection wiring to ensure it’s secure. Loose wiring may cause a short circuit and create safety hazards.
If you notice a decrease in battery capacity, first visit your local inspection station to determine the cause. If needed, maintenance can help improve the battery’s performance.

Installation

Securely fasten the battery; avoid vibration and loose mounting.
Check polarity before connection; prevent reverse wiring.
Use correct terminal hardware and torque.

Charging

Use a compatible smart charger (SLA mode).
Fully charge before first use; avoid deep discharge to 0%.
For storage, top‑up charge monthly to reduce sulfation.

Storage & Safety

Frequently Asked Questions (FAQ)

How long is the battery’s cycle life?

With proper use and maintenance, it can last about 300–500 deep cycles (discharged to around 70% before recharging). If you keep it in shallow cycles (less than 50% discharge), the lifespan will be even longer.

Does the battery require water refilling or maintenance?

No, this is a sealed, maintenance-free lead-acid battery. You don’t need to add water—just make sure the terminals stay clean and tightly connected.

How should I charge the battery correctly?

We recommend using a smart charger that matches the battery. The charging voltage should be 14.4–15.0V (for cycle use), and the float voltage should be 13.5–13.8V. Avoid overcharging and deep discharging.

How does the battery perform under extreme temperatures?

It is designed to operate between -20°C and +50°C. Capacity may decrease in very cold conditions, while high temperatures can shorten its lifespan. For best results, use and store it at room temperature.

Can the battery be installed sideways or upside down?

Yes, the sealed design allows it to be installed sideways. However, upside-down installation is not recommended.

What should I pay attention to when storing the battery?

Always store it fully charged in a cool, dry, and ventilated place. If stored for a long time, recharge it every 3–6 months to keep it in good condition.

What are the signs of insufficient capacity?

Typical signs include reduced driving range (for e-bikes), dimmer lights, shorter charging time, and a rapid voltage drop during discharge.

Can the battery be connected in parallel or series?

Yes. Parallel connections increase capacity, and series connections increase voltage. Just make sure you use the same brand, model, and condition of new batteries, and follow proper wiring instructions.
