How to Select the Right Load
Rule of thumb: load ≈ 3× Ah for 10 seconds. 30–40Ah → ideal with 100A. 50–60Ah → acceptable. 70Ah+ → use 200–300A.

Frequently Asked Questions
Quick answers about compatibility, load duration & shipping.
Q Is a 100A car battery load tester enough for my car?
A: For most small to mid-size 12V lead-acid batteries (≈30–60Ah), a 100A car battery load tester gives a realistic pass/fail in 10 seconds. For larger 70Ah+ batteries (diesel SUVs, luxury cars), use a 200–300A tester.
Q Which batteries is this for?
A: 12V automotive lead-acid batteries. Best results on 30–40Ah (perfect). Usable on 50–60Ah (acceptable). For 70Ah+, a 100A load is too light—use a 200–300A tester for proper cranking simulation. Not for lithium or non-12V systems.
Q How long should I apply the load?
A: Apply 100A for 10 seconds only, then allow cooling for about 60 seconds before the next test.
Q What indicates a weak battery?
A: Rapid voltage sag under load or failure to recover after release indicates poor capacity and likely replacement.
Q Do you sell from Delhi and ship Pan-India?
A: Yes — dispatch from Delhi, delivery across India in 3–7 business days. Questions? Contact us.
