Compact two-pack battery analyser

The UMLIFE BT-886 ships as a twin pack of pocket-sized testers that fit a 93 by 65 by 14 mm footprint and weigh 32 g each. They are aimed at households and technicians who want a quick voltage check on common cylindrical and button cells without a bench meter.

Tests 1.5 V and 9 V chemistries with LCD bar graph

Each unit reads AAA, AA, C, D, N, 9 V (6F22) and 1.55 V button types, plus 3.7 V lithium sizes such as 10440, 14500, 16340, 18650 and 21700. The three-segment LCD shows poor, weak or good voltage status, but the tester cannot measure capacity under load or internal resistance.

Two testers in the box for parallel checking

The pack supplies two identical analysers so one can stay in a tool drawer while the other travels in a gadget bag. No batteries are included for the testers themselves, and there is no software or calibration certificate supplied.
