When you run out, you have to run out and buy more. Stay home with this pack of (24) "AA" and (12) "AAA" alkaline batteries from Polaroid. Box says they're good until 2021.

This beast of a 1000-Watt 12VDC to 120VAC power inverter from Schumacher measures 5" x 6" x 3" and has dual output with 2000-Watt surge and thermal protection capabilities. Fan-cooled and designed to be used with large batteries, like the kind under the hood of your car (this isn’t a whimpy cig plug inverter). Has an on-off switch, a USB 2.0 Amp jack, and a low-battery alarm. Includes (2) 14-gauge power cables, and an instruction manual.

Knowledge is power - in this case, battery power. You'll know from the easy-to-read gauge on this black-plastic handheld mini-tester whether a battery is good, low or needs to be replaced. The 4-1/4" x 2-3/8" x 1" tester reads "AAA," "AA," "C," "D," 9 volt, 1.5 volt button, and other sizes.

The other day we heard someone in the warehouse shouting, “I'm rich! I'm rich!” It was Pat, who thought he was standing in front of a gigantic pile of quarters. We had to tell him they were Panasonic industrial CR2032 coin cell batteries. Can't blame him, though—they look awfully similar. These are take-outs from medical equipment, and we’ll send you (50) 2-packs with each order. We’ve spot-checked a bunch of them with a voltmeter (which showed over “3 volts” power), and a battery tester (which put their strength in the green/good range). So, they’re ready to go. Help us keep these 466,000 “quarters” out of a landfill. But don’t try using them for laundry. Pat already did, and it didn’t work out well.

24-Packs of your favorite sized "AA" and "AAA" alkaline batteries. Jarvis loves these as they are platinum series, long lasting alkalines with a 10 Year Shelf Life, leak proof upto 2 years and are mercury and cadmium free. You choose the "AA" or "AAA" packs. Now get out there an power something!

These Farpoint alkaline batteries have an expiration date of 2030 but you're going to use them up long before that the way you ride that remote. All are the standard 1.5V, and guaranteed leakproof for two years. You pick an 8-pack of AA or AAAs. Or get a couple packs of both – 2030!

These super handy little tweezer-style battery testers are made for checking button-cell and 3V lithium coin-cell batteries, but they've got a wide enough spread for everything from "AAA"s to D-cells (but not 9-volts!). Red and black arms designate the +/- sides, and an LED at the base lights up if the battery is good.

It’s a surplus "D" medical grade alkaline battery bonanza! These 15.25Ah  (15,250mAh) 12V alkaline battery packs have (8) standard sized 1.5V “D” cells stacked in (4) plastic-wrapped columns of (2). The pack is soldered together, and can be used as-is or easily separated and used as extremely long-lasting alkaline batteries for devices. New, but originally intended for use in medical equipment. MFG date of 06/2019 so they are fresh! Pack measures 5.39" X 4.84" X 1.35". That's only .75/each battery. Isn't surplus wonderful. 

Nice, new 6-volt lantern batteries from Ultralast®, labeled for the international market. Standard 2-5/8" square x 3-3/16" high, standard spring tabs on top. Advanced Heavy-Duty the label says. We'll price it to save you a world of dollars, pesos and francs, Pat says.

We’re talking batteries here. If you’re holdin’ ’em and you’d rather have something else hold ’em, get yourself a battery holder. Duh. Ours is 3” x 2-1/4” x approx 1” (with a front panel just under 1-1/2” thick), and holds (8) AA batteries. That’s (4) per side for all the Humanities majors out there who couldn’t have pictured that. Has a 14” barrel jack power cord to plug into whatever your batteries are powering.
