2️⃣ Types of Osaka Solar Batteries
Osaka offers different types of batteries, each designed for specific user needs.
1. Lead Acid Batteries
✅ Most commonly used battery
✅ Affordable price
✅ Requires regular maintenance
What is a Lead Acid Battery?
A Lead Acid Battery is a type of rechargeable battery that uses lead plates and sulfuric acid to store and deliver electrical energy. It is one of the oldest and most widely used battery technologies, known for its affordability, reliability, and high power output.
How It Works:
- Electrodes: Made of lead (Pb) and lead dioxide (PbO₂).
- Electrolyte: A solution of sulfuric acid (H₂SO₄).
- Chemical Reaction: During discharge, a chemical reaction between lead, lead dioxide, and sulfuric acid generates electricity.
- Rechargeable: When charged, the reaction is reversed, restoring the battery's energy.
Types of Lead Acid Batteries:
- Flooded Lead Acid (FLA)
:Requires regular maintenance (adding water).- Sealed Lead Acid (SLA):
-
Maintenance-free and spill-proof. - Deep Cycle Battery:
Designed for long-lasting power (used in solar systems, UPS, etc.). - Starter Battery:
Provides high current for vehicles (cars, motorcycles, etc.).
Advantages:
✔ Low Cost
✔ Reliable & Durable
✔ High Power Output
✔ Recyclable
Disadvantages:
✖ Heavy & Bulky
✖ Requires Maintenance (FLA Type)
✖ Shorter Lifespan Compared to Lithium Batteries
2.AGM (Absorbent Glass Mat) Batteries
✅ Maintenance-free
✅ Provides longer backup and lifespan
✅ Slightly more expensive
What is an AGM (Absorbent Glass Mat) Battery?
An AGM Battery (Absorbent Glass Mat) is a type of sealed lead-acid (SLA) battery designed for high performance, durability, and maintenance-free operation. It uses a special fiberglass mat to absorb the electrolyte, preventing leaks and making it safer and more efficient than traditional flooded lead-acid batteries.
How It Works:
- Absorbent Glass Mat (AGM): A fiberglass mat is placed between lead plates, soaking up the electrolyte like a sponge.
- Sealed & Spill-Proof: The electrolyte stays absorbed, preventing leaks and reducing maintenance.
- Faster Charging & Higher Efficiency: AGM batteries charge faster and provide higher power output with minimal energy loss.
Advantages of AGM Batteries:
✔ Maintenance-Free
– No need to add water.
✔ Spill-Proof & Safe
– Can be installed in any position.
✔ Faster Charging
– Charges up to 5 times faster than flooded batteries.
✔ Longer Lifespan
– Lasts longer than traditional lead-acid batteries.
✔ High Power Output
– Delivers strong bursts of energy for quick starts.
✔ Low Self-Discharge Rate
– Holds charge longer when not in use.
Disadvantages of AGM Batteries:
✖ Higher Cost
– More expensive than flooded lead-acid batteries.
✖ Sensitive to Overcharging
– Requires a proper charge controller to avoid damage.
Common Uses of AGM Batteries:
🔋 Solar Energy Storage (Home & Off-grid Systems)
🚗 Automotive & RV Batteries (Reliable for Start-Stop Technology)
🚤 Marine & Boats (Handles vibrations and deep discharge)
🔦 UPS Systems & Backup Power (Provides emergency power during blackouts)
🏍 Motorcycles & ATVs (Compact and high-power solution)
3. Gel Batteries.
✅ Longer lifespan than lead-acid
✅ Better discharge rate
✅ Superior performance
What is a Gel Battery?
A Gel Battery is a type of sealed lead-acid (SLA) battery that uses gelified electrolyte instead of liquid. It is designed for deep-cycle applications, providing longer life, better durability, and maintenance-free operation.
How It Works:
- Gel Electrolyte: Sulfuric acid is mixed with silica, turning it into a thick gel.
- Sealed & Maintenance-Free: No need to add water, and it's spill-proof.
- Deep Discharge Protection: Can discharge more deeply without damage, making it ideal for solar and backup systems.
Advantages of Gel Batteries:
✔ Maintenance-Free & Spill-Proof – No water refilling needed.
✔ Longer Lifespan – More charge cycles than traditional lead-acid batteries.
✔ Deep Discharge Capability – Handles deep discharges without losing performance.
✔ Vibration & Shock Resistant – Ideal for off-road vehicles, marine, and industrial use.
✔ Works in Extreme Temperatures – Performs better in hot and cold environments than flooded or AGM batteries.
✔ Low Self-Discharge – Holds charge for long periods when not in use.
Disadvantages of Gel Batteries:
✖ Higher Cost – More expensive than standard lead-acid and AGM batteries.
✖ Slower Charging – Takes longer to charge compared to AGM batteries.
✖ Sensitive to Overcharging – Needs a special charge controller to prevent damage.
Common Uses of Gel Batteries:
🔋 Solar Energy Storage – Used in off-grid and hybrid solar systems.
🚤 Marine & Boats – Performs well in harsh environments.
🏕 RV & Camping Batteries – Reliable power for long trips.
