Review: First class - Excellent meter, great price too! Review: For a few pounds more than a battery tester I have a reliable multimeter - I needed a good battery tester, having experienced that the usual cheap ones were not very reliable. I decided that I may as well invest in a multimeter that could test batteries. I'm very pleased with this - exceptional quality for the price (YouTube reviews attest to build quality) - and it will test 1.5V / 9V batteries 'under load' to give an accurate remaining voltage reading. You have to use the supplied leads to 'touch' the battery +/-contacts so perhaps not as convenient as many specific battery testers, but this multimeter does have a built-in stand which means you have both hands free. ## Features - VERSATILE FUNCTIONALITY: Measures AC/DC voltage up to 600V, 10A DC current, 2MΩ resistance; additional features include continuity, diode test and battery test - LEAD-ALERT PROTECTION: LEDs on the meter illuminate to indicate proper test lead placement, enhancing accuracy and safety during measurements - BACKLIT DISPLAY: LCD shows clear readings in low-light conditions for enhanced visibility - BATTERY TEST: Battery test mode can be used for checking if batteries are working - CONVENIENT FEATURES: Test lead holders on the back of the meter, kickstand and optional magnetic hanger (Cat. Nos. 69445 or 69417) for hands-free operation - DURABLE CONSTRUCTION: Built to withstand a 6.6-Foot (2 m) drop, for use in basic and controlled electromagnetic environments such as residential, business and light-industrial locations - COMPLETE PACKAGE: Includes test leads with CAT III/CAT IV safety caps, instructions, and 2 x AAA batteries ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B57L9FNL | | Best Sellers Rank | 40,007 in DIY & Tools ( See Top 100 in DIY & Tools ) 49 in Multi Testers | | Brand | KLEIN TOOLS | | Colour | Orange/ Black | | Compatible Devices | Electrical devices and components | | Country Of Origin | Afghanistan | | Customer Reviews | 4.7 out of 5 stars 2,860 Reviews | | Global Trade Identification Number | 00092644693731 | | Included Components | Multimeter, Voltage Tester | | Item Dimensions | 23.7 x 12.9 x 9.7 centimetres | | Item Length | 6.41 Inches | | Item Type Name | Building Material | | Item Weight | 395 g | | Item Width | 3.13 Inches | | Item dimensions L x W x H | 23.7 x 12.9 x 9.7 centimetres | | Item weight | 395 g | | Manufacturer | Klein Tools | | Manufacturer Part Number | MM325 | | Maximum Operating Voltage | 600 Volts | | Measurement Type | Multimeter | | Minimum Operating Voltage | 9 Volts | | Model Number | MM325 | | Number of Items | 1 | | Number of Packs | 1 | | Power Source | Battery Powered | | Power source | Battery Powered | | Specification Met | Cat Iii 600v Safety Rating | | Style | Protection,Safety | | Style Name | Protection,Safety | | UPC | 092644693731 | | Unit Count | 1.0 count | | Upper Temperature Rating | 60 Degrees Celsius | ## Product Details - **Brand:** KLEIN TOOLS - **Colour:** Orange/ Black - **Item weight:** 0.87 Pounds - **Power source:** Battery Powered - **Style:** Protection,Safety ## Images ![MM325 Multimeter, Digital Manual-Ranging 600V AC/DC Voltage Tester, Tests Batteries, Current, Resistance, Diodes, and Continuity,Black - Image 1](https://m.media-amazon.com/images/I/51EPzXFvIAL.jpg) ![MM325 Multimeter, Digital Manual-Ranging 600V AC/DC Voltage Tester, Tests Batteries, Current, Resistance, Diodes, and Continuity,Black - Image 2](https://m.media-amazon.com/images/I/61C767ri-YL.jpg) ![MM325 Multimeter, Digital Manual-Ranging 600V AC/DC Voltage Tester, Tests Batteries, Current, Resistance, Diodes, and Continuity,Black - Image 3](https://m.media-amazon.com/images/I/61K7-fwWjqL.jpg) ![MM325 Multimeter, Digital Manual-Ranging 600V AC/DC Voltage Tester, Tests Batteries, Current, Resistance, Diodes, and Continuity,Black - Image 4](https://m.media-amazon.com/images/I/61Cgh9FcqWL.jpg) ![MM325 Multimeter, Digital Manual-Ranging 600V AC/DC Voltage Tester, Tests Batteries, Current, Resistance, Diodes, and Continuity,Black - Image 5](https://m.media-amazon.com/images/I/51-H06Q9aFL.jpg) ## Available Options This product comes in different **Pattern** options. ## Questions & Answers **Q: Does this have auto power off?** A: yes **Q: how long are the test leads?** A: The leads are 38 Inches long. **Q: Does it check Hz ?** A: The MM325 checks Frequency /Duty Cycle 1 Hz-50kHz **Q: whats the lowest voltage reading?** A: Lowest voltage ranges are 200mV DC and 200V AC. ## Customer Reviews ### ⭐⭐⭐⭐⭐ First class *by A***F on 26 December 2025* Excellent meter, great price too! ### ⭐⭐⭐⭐⭐ For a few pounds more than a battery tester I have a reliable multimeter *by D***. on 5 March 2025* I needed a good battery tester, having experienced that the usual cheap ones were not very reliable.
