How To Choose The Right Inverter Battery For Home Backup
Understanding Ah rating, backup time, family load, and why the cheapest battery is usually not the best value.
Step 1: Calculate Your Home Load
Before choosing a battery, list all the appliances you want to run during a power cut. A typical home may need to run 3 fans (75W each), 4 LED lights (10W each), 1 TV (80W), and 1 router (15W). That adds up to roughly 360 watts.
This load number directly determines how much Ah (Ampere-hour) capacity you need. Higher load means a higher Ah battery, or shorter backup time.
Step 2: Understand Ah Rating
Ah stands for Ampere-hour, which measures how much charge a battery can store. Common inverter battery sizes are:
- 100Ah — Suitable for small homes with 2-3 fans and a few lights (2-3 hours backup)
- 150Ah — The most popular choice for Indian homes, good for 3-4 fans, lights, TV, and router (4-5 hours backup)
- 180Ah — For larger homes or people who need extended backup (5-7 hours)
- 200Ah+ — For offices, shops, or homes with heavy loads
Step 3: Choose Between Flat Plate and Tubular
Flat plate batteries are cheaper but have a shorter lifespan (2-3 years). Tubular batteries cost 20-30% more but last 4-5 years, handle deep discharges better, and require less maintenance. For home backup, we always recommend tubular batteries — they pay for themselves over time.
Step 4: Pick a Trusted Brand
We deal in Exide, Luminous, Amaron, Microtek, and Su-Kam. All come with official warranty and GST billing. Each brand has its strengths:
- Exide — Best after-sales network, widest model range
- Luminous — Strong brand trust, good warranty process
- Amaron — Known for durability and low water loss
Step 5: Consider Your Budget Realistically
Inverter battery prices typically range from ₹8,000 to ₹20,000 depending on Ah, brand, and type. Don't just pick the cheapest option — a ₹9,000 flat plate battery that dies in 2 years costs more per year than a ₹13,000 tubular battery lasting 5 years.
