The SLIGC6VAGM 225AH 6V is a sealed AGM (Absorbent Glass Mat) deep-cycle battery designed for golf carts, off-grid systems, and industrial equipment. It delivers 225Ah capacity at 6V, providing sustained power with minimal maintenance. Its AGM construction enhances vibration resistance and leak-proof operation, optimized for frequent deep discharges. Pro Tip: Always use temperature-compensated chargers (14.4–14.8V) to prevent sulfation.

What defines the SLIGC6VAGM 225AH 6V battery?
The SLIGC6VAGM combines AGM technology, 225Ah capacity, and 6V configuration for heavy cycling. Unlike flooded batteries, its electrolyte is suspended in fiberglass mats, enabling spill-proof installation at any angle. With 1,200+ cycles at 50% DoD, it outperforms standard lead-acid models in lifespan. Pro Tip: Pair multiple units in series (e.g., 6 x 6V for 36V systems) for higher voltage needs.
Why choose AGM over flooded lead-acid?
AGM batteries like the SLIGC6VAGM eliminate liquid electrolyte risks, offering maintenance-free operation and faster recharge rates. They handle 2–3x more cycles than flooded equivalents due to lower internal resistance. Real-world example: A 6V 225Ah AGM powers a golf cart for 45–55 holes per charge vs. 30–40 with flooded. Warning: Never exceed 15V during charging—AGM plates degrade rapidly beyond this threshold.
| Feature | SLIGC6VAGM (AGM) | Flooded Equivalent |
|---|---|---|
| Cycle Life | 1,200 cycles | 500 cycles |
| Recharge Time | 5–6 hrs | 8–10 hrs |
| Maintenance | None | Monthly watering |
Where is the SLIGC6VAGM commonly used?
Beyond golf carts, this battery suits solar storage, floor scrubbers, and marine trolling motors. Its 6V design allows scalable voltage configurations—eight units create 48V systems for solar farms. Practically speaking, one 225Ah 6V AGM can run a 300W RV fridge for ~12 hours. Pro Tip: Avoid partial charging; AGM performs best when cycled between 50–100% SoC.
How to charge the SLIGC6VAGM correctly?
Use a 3-stage charger with absorption voltage of 7.2–7.4V (per 6V unit) and float voltage at 6.8V. Temperature compensation (-3mV/°C per cell) prevents overcharge in hot environments. Real-world example: Charging eight 6V AGMs in a 48V bank requires 57.6–59.2V absorption. Warning: Multi-bank systems require balanced wiring—voltage drops over 0.2V cause uneven aging.
| Parameter | AGM Requirement | Flooded Equivalent |
|---|---|---|
| Absorption Voltage | 7.2–7.4V | 7.3–7.5V |
| Float Voltage | 6.8V | 6.6V |
| Max Charge Current | 30% of Ah | 20% of Ah |
What’s the lifespan under typical use?
With proper charging, expect 4–7 years (vs. 2–4 for flooded). Depth of discharge (DoD) is critical—50% DoD yields 1,200 cycles, but 80% DoD cuts it to 500. For example, daily cycling in a golf cart depletes ~60%, lasting ~3 years. Pro Tip: Annual equalization at 7.5V for 2–3 hours combats sulfation but disconnect loads first!

FAQs
Yes—AGMs share similar voltage profiles but verify tray dimensions. SLIGC6VAGM measures 10.3″L x 7.1″W x 10.9″H; some flooded models are taller.
Does cold weather affect performance?
AGMs retain ~80% capacity at -20°C vs. 60% for flooded. However, charge at 0°C requires +0.3V per cell to offset slower ion movement.
How to store when not in use?
Keep at 50–80% SoC in 10–25°C environments. Charge every 3–6 months—AGM self-discharge is 1–3% monthly (vs. 5–10% for flooded).
