🔋 What is Exide 2V 100Ah Battery?

An Exide 2V 100Ah battery is an industrial VRLA cell used in battery banks.

👉 Typical system setups:

12V → 6 batteries
24V → 12 batteries
48V → 24 batteries

These batteries are ideal for:

Solar systems
UPS backup
Telecom towers
Data centers

⏱️ Basic Backup Time Formula

🔢 Formula:

Backup Time (Hours) = (Battery Capacity × Voltage × Efficiency) ÷ Load

🔍 Example Calculation

👉 Suppose:

System: 12V (6 batteries)
Capacity: 100Ah
Load: 200W

Backup = (100 × 12 × 0.8) ÷ 200 = ~4.8 hours

⚡ Real Backup Time Scenarios

🔹 Scenario 1: Home UPS

Load: 150W
Backup: ~6–7 hours

🔹 Scenario 2: Office Setup

Load: 300W
Backup: ~3–4 hours

🔹 Scenario 3: Solar System

Depends on battery bank size
24 batteries → longer backup

📊 Important Insight

✔ Capacity @ C10 Rating

100Ah at 1.75V per cell

✔ Temperature Effect

From graph:

At 25°C → optimal performance
At higher temperature → capacity drops faster

✔ Discharge Rate Effect

From chart:

Higher load = faster discharge
Lower load = longer backup

👉 Meaning:
Backup time is NOT fixed — it changes based on usage.

🔥 What Affects Battery Backup Time?

⚡ 1. Load (Most Important)

Higher load → less backup

🌡️ 2. Temperature

High heat reduces:

Capacity
Battery life

🔋 3. Depth of Discharge (DoD)

Deep discharge reduces backup consistency

🔁 4. Charging Condition

Full charge → maximum backup
Partial charge → reduced backup

🔧 5. Battery Health

Old batteries:

Lose capacity
Give less backup

🛠️ Tips to Increase Backup Time

✅ Avoid Overloading

Use within capacity limit

✅ Maintain Proper Charging

Use correct charger
Avoid overcharging

✅ Keep Temperature Stable

Ideal: 20–25°C

✅ Use Proper Battery Bank

More batteries → more backup

✅ Regular Maintenance

Check:

Voltage
Connections
