Avoid Deep Discharges
Try not to drain the battery completely before recharging. Keeping the charge above 30% will prevent unnecessary stress on the cells.
Charge Regularly
Make it a habit to recharge after daily use, even if the battery is not fully drained. Frequent small charges are better than rare deep charges.
Use the Right Charger
Always use a charger designed for lead-acid batteries with the correct voltage and amperage. A smart charger with pulse or float charging is highly recommended.
Maintain Proper Charging Conditions
Charge the battery in a cool, ventilated place. Avoid direct sunlight or closed, hot spaces that can overheat the battery.
Check Water Levels (Flooded Types)
For flooded lead-acid batteries, check electrolyte levels regularly and top up with distilled water when needed. Never use tap water.
Keep Terminals Clean
Dirt and corrosion on terminals reduce efficiency. Clean connections regularly and apply a thin layer of petroleum jelly or anti-corrosion grease.
Avoid Overloading the Vehicle
Excessive weight increases power draw, causing deeper discharges and shorter battery life. Stay within the recommended load limit.
Give It a Full Charge Weekly
Even if you only use the battery lightly during the week, give it one complete charge cycle to keep it balanced and healthy.
Store Properly During Long Breaks
If the vehicle won’t be used for weeks, store the battery fully charged and recharge it every 2–3 weeks to prevent self-discharge.
Drive Smoothly
Aggressive acceleration or frequent stop-and-go puts extra strain on the battery. Smooth driving helps conserve energy and extend battery life.

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

Store in a cool, dry, ventilated place; avoid direct sunlight.
Do not charge in sealed or high‑temperature environments.
Follow local recycling and disposal regulations.

Frequently Asked Questions (FAQ)

How long is the cycle life of the battery?

Under standard conditions, the battery provides 500–800 cycles (based on 70% depth of discharge). For float use (such as UPS), the lifespan can reach 3–5 years.

Does the battery require regular maintenance?

No. This is a sealed, maintenance-free lead-acid battery. There is no need to add water—simply keep the terminals clean and connections secure.

How should I charge the battery properly?

We recommend using a smart charger. The charging voltage should be 14.4–15.0V (for cyclic use), and the float voltage should be 13.5–13.8V. The recommended charging current is ≤0.25C (25A). Avoid overcharging and deep discharging.

Can the battery be stored for long periods?

Yes. Make sure the battery is fully charged before storage. Keep it in a cool, dry, and ventilated place at 5–25°C. If stored for more than 3 months, recharge the battery to prevent excessive self-discharge.

How does the battery perform in extreme temperatures?

The operating temperature range is -20°C to +50°C. Capacity may decrease in very cold conditions, while high heat can accelerate aging. The best performance is achieved at 20–25°C.

Is this battery suitable for solar energy storage?

Yes. With its large capacity and deep-cycle capability, the 12V100Ah battery is well-suited for home and industrial solar storage systems. We recommend pairing it with an MPPT controller and a compatible charger.

How do I know when the battery needs replacement?

Signs include noticeably shorter discharge times, faster charging, rapid voltage drops under load, or a significant increase in internal resistance.

Can the battery be connected in series or parallel?

Yes. Series connection increases voltage, while parallel connection increases capacity. Always use batteries of the same model, capacity, and batch, and ensure they are in the same state of charge.
