Multi-Type Battery Tester with Voltage, Percentage & Internal Resistance Testing

B3 - Battery Tester

Dlyfull's multi-type battery tester features an LCD display, testing voltage, charge percentage, and internal resistance for a wide range of batteries. With probe-style operation and low standby power consumption, it delivers quick and accurate battery status checking:
1. Multi-type battery tester supporting 11 types of batteries: 1.2V Ni-MH, 1.5V alkaline, 1.5V button cells, 3.0V lithium button/cylindrical, 3.2V LiFePO4, 3.7V Li-ion, 9.0V alkaline, and 12.0V remote control batteries
2. Tests battery voltage (2 decimal places), charge percentage (5%-100%), and internal resistance (0-999R)
3. Powered by two AAA 1.5V alkaline batteries
4. LCD display with 4-level battery power symbol for internal power status
5. Red and black test probes – red to positive, black to negative; reverse connection does not damage the product
6. Automatic sleep mode – enters sleep after 60 seconds of inactivity to save power; wake up by touching probe to battery or turning the switch
7. Power-off switch completely disconnects internal power when not in use
8. Low standby power consumption – energy-saving and durable
9. Reverse polarity protection – safe operation without damaging the tester
10. Compact design: 135×75.5×28mm (tester only), 148g
