Description
Digital Battery Tester with LCD Display, an AA Battery Checker for Every Cell in the Drawer
-
Capacity in mAh: a sophisticated algorithm calculates capacity and shows it on the LCD screen
-
Precise voltage checks: measures voltage accurately and displays it in volts on the same screen
-
Works with most chemistries: reads alkaline, lithium, zinc-carbon and nickel-cadmium cells
-
Fits standard sizes: compatible with AA, AAA, C, D, 9V and button cell batteries
-
Insert and read: drop the cell into the right slot and testing starts automatically
-
Compact and portable: small enough to live in a drawer, toolbox or travel bag
Unlike battery testers that report only volts, this one calculates capacity as well. A sophisticated algorithm works out the battery capacity and shows the result on the LCD screen in mAh, or milliampere-hour, and it measures voltage accurately and prints it in volts on the same large, easy-to-read display. It gives accurate and precise readings for alkaline, lithium, zinc-carbon and nickel-cadmium cells.

As a household battery tester it is compatible with most standard cylindrical batteries, including AA, AAA, C, D, 9V and button cell, so it serves as an aa battery tester, an aaa battery tester and a 9V checker in one. Insert the battery into the appropriate slot and the tester automatically detects the type and starts testing, which makes it versatile enough for remote controls, flashlights, toys, smoke alarms, cameras and power tools.

The voltage range covers 0.5V to 4.5V, which spans the majority of batteries commonly used in electronic devices, and the capacity figure matters most with rechargeable cells because it shows how much charge is actually left and when a pack needs recharging rather than throwing away. This small battery tester measures 3.62 x 2.48 x 0.55 in (92 x 63 x 14 mm) in a compact silver housing and runs on 1 button battery, which is not included.

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