00:00You know that drawer, the one crammed with loose AAs, a few AAs, some random button cells,
00:04and absolutely no idea which ones still have life in them?
00:08Yeah, I've got one too, and I finally got tired of the stick it in the remote and see what
00:12happens
00:13method. So I went digging and rounded up the 5 best battery testers people are actually buying
00:18right now, and honestly, none of these will cost you more than a coffee. Let's get into it.
00:25First up is the Anung BT-169. This one's my personal favorite because it needs zero batteries to run,
00:32it draws power straight from whatever you're testing, which is exactly what you want from
00:35a tool that lives in a junk drawer for six months at a time. It handles AA, AAA, 9V, button
00:41cells,
00:42and even 18,650 lithium cells, and it gives you an actual digital voltage reading instead of some
00:48vague red-yellow-green guess. It's $5.37, nearly 5,000 sold, and a 4.9 rating.
00:56If you want one tester that just covers everything, this is it.
01:00Next is the Anung BT-189, and this one's the budget champ at $3.26.
01:06It's got a clean LCD display and it covers pretty much every household size, 9V, N, DVC, AA,
01:12AAA, plus button cells. What I like is how simple it is, two contacts, slide the battery in,
01:19read the number. No menus, no modes, no thinking required. Over 4,700 people have bought it with
01:27a 4.8 rating. Honestly, at this price I'd grab two, one for the house, one for the garage.
01:34Coming in third, the Anung BT-168 Pro. The big deal here is that it's a load tester,
01:40not just a voltmeter. That difference actually matters, because a dead battery can still read
01:45close to full voltage until you put a load on it, then it collapses. This one tests under load,
01:51so you get the truth about what's left in that cell. It's $3 flat, has a 4.9 rating,
01:57and over 4,400 sold. For anyone who's been fooled by a good battery that died 10 minutes later,
02:04this is your fix. Number 4 is the BT-860 Universal Battery Tester.
02:10This is the analog style one with the needle indicator, and there's something genuinely
02:14satisfying about it, no screen to squint it, just a needle swinging into the green, yellow,
02:19or red zone. It handles 9V, 1.5V AA, and AAA, and button cells, and the sliding arm makes it
02:26easy
02:26to test different lengths one-handed. $4.75, a 4.9 rating, 4,000 sold. If you want something dead
02:34simple that anyone in the house can pick up and use, this is the one.
02:39And rounding out the list, the BT-168 with the color display. This is basically the upgraded,
02:45easier-to-read version, you get the voltage number plus a color-coded bar, so you instantly know if
02:50it's good, weak, or trash without interpreting anything. It covers AA, AAA, C, D, 9V, and button
02:57cells, so nothing in your drawer gets left out. It's $5.28 with a 4.8 rating. If you're testing
03:05a
03:05big pile of batteries at once, that color display saves you a surprising amount of squinting.
03:11All five of these are linked down in the description, so go grab whichever one fits your setup best.
03:16If this helped you clear out that battery drawer, do me a favor and hit that like button,
03:21and subscribe if you want more cheap tools that punch way above their price.
03:25Thanks for watching, and I'll see you in the next one.
