A resting voltage flatters a cell; a load test does not · review
A tester covering the widest cell list here — including CR123A and CR2 photographic lithium cells — reporting GOOD, WEAK or LOW on an LCD.
What the figures leave us with The one that accepts photographic lithium cells. That is the reason to choose it over the cheaper testers here.
The widest cell list in this hub, including the ones people actually waste.
Testing of the common household batteries — AA, AAA, C, D and 9 V — as well as CR123A, CR2 and button cells. A clear LCD display showing the battery state as GOOD, WEAK or LOW. Simple use requiring no technical knowledge: insert the cell and read the result.
CR123A and CR2 cells cost several euros each and live in equipment that is used intermittently — cameras, torches, sensors, alarm contacts. They are replaced on suspicion far more often than on evidence, because nothing in the house can test them. A tester with a cradle for them pays for itself in cells not thrown away.
Three states instead of a number is less information. It is also unambiguous, which for a tool used by whoever finds it in the drawer is a defensible design.
No such listing: the American Amazon shop answers the reference with a search box rather than a page.

They are 3 V lithium cells used in cameras, torches, sensors and alarms. They are expensive, they are thrown away while still good, and most household testers have no cradle for them.
For deciding whether to fit a cell, yes. For tracking how a cell is aging, no — a numeric voltage is more informative, and the TFA Dostmann here gives one.
The listing does not say. Battery-free testers draw from the cell being tested; this one is not described either way.

The one that accepts photographic lithium cells. That is the reason to choose it over the cheaper testers here.
A reference exists on these Amazon stores: France, Germany, Italy, Spain. Listed is not the same as in stock — availability changes daily.
Details checked on August 31, 2026.
Anyone with camera, torch or sensor lithium cells that no other tester in this hub accepts.
Amazon reports what buyers took in the month before this page was last checked: at least 200.
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.
