## Overview

The DLG DI-225 Battery Load Tester is a compact, high-precision tool designed exclusively for low capacity 6V and 12V lead-acid batteries ranging from 5AH to 80AH. Featuring a 4-wire Kelvin testing method, a built-in 10-second load timer, and comprehensive safety protections including overload and reverse polarity safeguards, it delivers fast, reliable diagnostics of battery health and charging system status. Ideal for professionals managing electric vehicle or UPS batteries, this tester combines accuracy, durability, and portability in one sleek device.

## Description

DI-225 can quickly and accurately judge the no-load energy, the on-load condition, the intenal resistance of the battery and the charging system conditions of 6V and 12V lead-acid storage battery. It is provided with 32-bit high-end micro control unit for computation operation to automatically tell the battery with different voltage(6V or 12V) at the same time and the charging status. Moreover, this instrument is internally provided with reverse polarity protection, over voltage input protection, poor contact prompt and over-temperature prompt. Therefore, it can be simply and conveniently carried out. Please note that when operating test, make sure clips are firmly and fully connected to the terminals of battery. Due to small size of metal terminals for low capacity lead-acid battery, any loose or partly connection will result in ERR indication or over high voltage readings. Please note Ah value is required to preset into the instrument prior to testing. It is visible listed on the battery label. CCA value is not available at all. So please make sure you know the Ah of your tested battery.

Review: Great Battery Tester! - This is one great battery tester for small batteries. I use it to test my many UPS batteries. This tester looks like it is made very well. It uses a 4 wire Kelvin testing setup for more accuracy. If you need to test lower amp batteries this is the tester you want to get!
Review: No longer confused ;) - Just recieved this. When it is connected, the no load voltage is reading 26.83v and my fluke meter indicates 12.44v. This is a 12v 5ah lead acid battery. Updating my review. So I found that there is an isolated contact within the clamp that must make contact with the pattern terminals and if they do not, the high voltage reading is an indication that the connection is not good. Now that I have figured that out I absolutely love this thing. Very quick assessment of my UPS batteries

### ⭐⭐⭐ Cheap price, cheap made.
*by K***D on October 9, 2018*

This works, but it is not as accurate or well built as I'd like. The clips are very cheap, and we connection errors because of the. Sometimes it will also give different readings on the same battery, Good for confirming a suspect battery is definitely dead though.
