Description
Digital Battery Testers, Battery Checker for AA, AAA, C, D, 9V and Button Cell
-
Stop guessing which cells are dead: a sophisticated algorithm calculates capacity, so you see how much charge is really left
-
Small enough to keep handy: the compact silver housing fits a drawer, toolbox or travel bag
-
Insert and read: drop the cell into the right slot and testing starts automatically
-
Easy to read at a glance: the large LCD shows capacity in mAh and voltage in volts on one screen
-
Works with the cells you own: it reads alkaline, lithium, zinc-carbon and nickel-cadmium batteries
Before you toss a battery or trust it in a smoke alarm, find out what is actually left in it. This battery checker calculates capacity as well as voltage, and the large, easy-to-read LCD shows both at once. It runs on 1 button battery, which is not included.
A sophisticated algorithm works out the capacity and shows it in mAh, or milliampere-hour, while the voltage reads out accurately in volts on the same screen. Insert the battery into the appropriate slot and the tester detects the type and starts testing, so it serves as an AA battery tester, an AAA battery checker and a 9V checker in one for remote controls, flashlights, toys, smoke alarms, cameras and power tools.
As a battery health tester it matters most with rechargeable cells, because the capacity figure shows when a pack needs recharging rather than throwing away. This small battery tester measures 3.62 x 2.48 x 0.55 in (9.2 x 6.3 x 1.4 cm) in a compact silver housing.

FAQs
Q: What battery sizes does this digital battery tester work with?
A: It is compatible with most standard cylindrical batteries, including AA, AAA, C, D, 9V and button cell.
Q: Does it show remaining capacity or only voltage?
A: Both: the LCD shows the calculated capacity in mAh and the measured voltage in volts.
Q: What voltage range does it cover?
A: 0.5V to 4.5V, which spans the majority of batteries commonly used in electronic devices.
Q: Can I test rechargeable batteries?
A: Yes, and the capacity reading is especially useful because it shows how much charge is left and when they need recharging.
Q: Do I need a battery for the tester itself?
A: It runs on 1 button battery, which is not included.
