A resting voltage flatters a cell; a load test does not · review
A tester covering almost every household cell at 1.2, 1.5, 3.0 and 9 V, displaying the remaining voltage in volts alongside a color-scaled charge state.
What the figures leave us with The one that shows you a number instead of a color. That alone makes it the more useful of the two cheap testers here.
A tester whose output is a voltage rather than a verdict.
Suitability for almost all battery types — primary cells and rechargeables in AAA, AA, C and D — plus button cells at 1.2 V, 1.5 V, 3.0 V and 9 V. Simple operation for quick checking of batteries and rechargeables, described as ideal for establishing the charge state of cells found in a drawer. A digital display giving the remaining battery voltage in volts, with a color-scaled charge state.
Every cheap battery tester shows a green-amber-red scale. Only some also show the voltage. The difference matters because the scale is calibrated to one assumption about what “good” means, and the voltage lets you apply your own — a 1.3 V alkaline is fine for a clock and useless for a camera flash.
Whether the cell is loaded during the reading. It is the specification that separates this category from a voltmeter, and neither of the two cheapest testers here states it.
Catalogued and unsold: the American Amazon shop lists the reference with nobody behind it.

A traffic-light indication tells you the tester's opinion. A voltage lets you form your own: 1.35 V on an alkaline AA is a cell with life left, and no color band conveys that.
Nickel-metal-hydride rechargeables, whose nominal voltage is 1.2 V rather than 1.5 V. Testing them against an alkaline scale marks healthy cells as flat.
Not stated. As with the VARTA in this hub, the listing describes the display rather than the measurement method.

Sorting a mixed drawer, where the numeric voltage is the useful output.
Amazon reports what buyers took in the month before this page was last checked: at least 1,000.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.
Specifications: the manufacturer sheet for measuring instruments and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
AAA / AA / C / D / 9 V blocks · LCD charge state · no setup
A universal tester for primary and rechargeable cells with an LCD charge indication and no configuration — insert the cell and read.
Best for: A household tester where the only question is whether to bin the cell.
AA / AAA / C / D / 9 V / button cells · alkaline, NiMH, lithium, zinc-carbon
A tester covering every household cell size and four chemistries, showing the measured voltage and state of charge on an LCD, from a battery maker.
Best for: The drawer full of cells nobody can identify as good or flat.
6 V and 12 V lead-acid · 100–2000 CCA · battery, starter and charging tests
A different instrument from the rest of this hub: a vehicle battery tester using conductance measurement to check a 6 V or 12 V lead-acid battery, its starter draw and its charging system.
Best for: Diagnosing a car that will not start, where the question is the battery, the starter or the alternator.
