Stop guessing whether your battery is truly healthy — the BVIR Battery Tester gives you precise voltage and internal resistance readings in seconds, so you know exactly when to replace or keep using your batteries.

The BVIR Battery Tester measures both voltage (0–999 mΩ range for internal resistance) and actual cell health across AA, AAA, and 18650 lithium batteries using a professional-grade 4-wire measurement structure — the same technique used in lab-grade instruments. This eliminates contact resistance errors and delivers readings accurate to within 1%, far beyond what basic voltage-only testers can offer. The backlit LCD display ensures clear readings whether you're working in a bright workshop or a dimly lit storage room.

Designed for daily convenience, the tester runs on a built-in 3.7V / 1000mAh rechargeable battery that charges via USB Type-C (any 5V charger works). With up to 45 hours of runtime with backlight off and automatic sleep mode after 30 seconds of inactivity, it's built to last through long testing sessions without wasting power. A low-battery indicator ("LO" on screen) ensures you're never caught off guard. Ideal for electronics hobbyists, EV battery pack builders, solar energy enthusiasts, RC vehicle users, and anyone managing a fleet of rechargeable cells.

Backed by a 1-year warranty and direct Indian customer support via WhatsApp, call, or email, amiciKart ensures you're never left without help. Ships free across India with same-day dispatch for orders placed before 2 PM — delivered in 3–5 business days.

Get pinpoint accuracy every time — 4-wire measurement structure delivers ±1% accuracy for voltage and internal resistance (0–999mΩ) on AA, AAA, and 18650 cells, eliminating guesswork when testing lead-acid or lithium batteries
Two tests in one device — simultaneously measures both battery voltage AND internal resistance, saving you the cost and hassle of buying separate instruments
Never run out of power mid-test — built-in 3.7V/1000mAh rechargeable battery charges fully in just 1.5 hours via universal USB Type-C (any 5V charger works); backlight-off mode gives up to 45 hours of working time
Read results in any lighting condition — backlit LCD display can be toggled on/off with a single button press; auto sleep mode activates after 30 seconds of inactivity to conserve battery life
Built to last with 1,000+ charge cycles — the internal battery supports over 1,000 recharge cycles, and a low-power 'LO' indicator alerts you before the device shuts down
