Key Factors to Consider When Choosing a Battery
1. Power Requirement (Load Calculation)
You need to calculate the total load of appliances:
| Appliance | Approx Wattage |
|---|---|
| Fan | 70W |
| LED TV | 100W |
| Lights | 10–15W |
| Laptop | 50W |
Total load determines battery size.
2. Backup Duration
Decide how long you want power during outages.
Example:
-
- 2–3 hours → Medium battery
- 6–8 hours → High-capacity battery
3. Battery Capacity (Ah Rating)
Capacity is measured in Ampere-hours (Ah).
-
- 100Ah → Lower backup
- 150Ah → Medium
- 200Ah+ → High backup
4. Charging Time
Fast charging ensures your battery is ready quickly after power returns.
5. Maintenance Requirements
-
- Tubular → Low maintenance
- Flat plate → Higher maintenance
- Lithium → Minimal maintenance
6. Space & Installation
Ensure:
-
- Proper ventilation
- Safe placement
- Enough space
