The BT-168 Universal Battery Tester Checker is a simple yet effective tool for testing multiple battery types, including AA, AAA, C, D, 9V, and button cell batteries. This affordable 2-pack offers convenience without requiring batteries for operation. Based on extensive user feedback, this device provides good value despite its lightweight construction, helping households eliminate guesswork when dealing with used batteries and potentially saving money by identifying still-functional batteries that might otherwise be discarded.
Design and Build Quality
The BT-168 battery tester features a compact, lightweight design that prioritizes portability over premium feel. The testers come in a simple package – often described as a ziplock-type bag with just a product barcode sticker. The housing is made of basic plastic that some users describe as “cheap feeling,” which is expected given the low price point.
The device features a sliding red mechanism that moves to accommodate different battery sizes. A notable design limitation mentioned by many users is the lack of a spring mechanism to hold batteries in place during testing. This requires users to manually hold the battery while ensuring proper contact with the terminals, which can be awkward for certain battery sizes, especially smaller button batteries or shorter CR123 types.
Despite the basic construction, most users find the device functional when handled carefully. As one user succinctly put it, “It’s cheaply made, but it works.”
Functionality
The BT-168’s primary appeal is its versatility in testing multiple battery types. It can test:
- AA and AAA batteries (most commonly used sizes)
- C and D batteries
- 9V batteries
- Button/coin cell batteries (CR2032, etc.)
The tester requires no power source of its own, utilizing the battery being tested to power the analog meter. This is considered a significant advantage over digital testers that require their own batteries to function. The analog meter display is straightforward, with color-coded indicators showing “REPLACE” (red), “LOW” (yellow), and “GOOD” (green) zones.
Most users report accurate readings for standard battery sizes (AA, AAA, C, D), though some inconsistencies were noted with button batteries and in comparing readings between the two units in the package. The testing process is simple but requires proper technique – batteries must be properly aligned with terminals and held firmly in place.
The 9V battery testing feature utilizes separate contacts at the bottom of the device, which some users initially found confusing but appreciated once they figured out the proper technique.
User Experience
The user experience with this battery tester reflects its position as a basic, economical tool rather than a precision instrument. Key aspects of the user experience include:
- Ease of Use: The device is generally described as simple to operate, with instructions printed directly on the tester. However, the lack of a spring mechanism means users must hold batteries firmly in place while reading the meter, which some find awkward.
- Practicality: Users appreciate having a quick way to check batteries without needing to install them in devices. As one user noted, “This will save you a bunch of time and trips to buy batteries.”
- Convenience: The 2-pack offers flexibility to keep testers in different locations (e.g., “one upstairs, one downstairs” or “one in the house, one in the garage”).
- Battery Management: Many users report this tester helps them sort through collections of used batteries, eliminating dead ones and identifying those with remaining charge. One user described it as helping clean out a “giant tub of different size batteries.”
- Money Saving: A recurring theme in user feedback is the potential cost savings from reusing partially discharged batteries for less demanding devices rather than discarding them.
Performance and Accuracy
The performance of the BT-168 is generally considered adequate for casual home use but not suitable for precise technical applications. The analog meter provides a general indication of battery condition rather than exact voltage measurements.
Key observations on performance include:
- General Reliability: Most users find the tester reliable enough for household purposes, particularly for standard-sized batteries like AA and AAA.
- Inconsistencies: Some users report slight variations in readings between the two testers when testing the same battery, suggesting limited precision.
- Button Battery Challenges: Several users mention difficulty getting consistent readings with smaller button batteries due to their size and the challenge of maintaining good contact.
- Threshold Questions: A few technically-inclined users questioned the voltage thresholds used, with one noting the tester only indicates “REPLACE” at extremely low voltages (around 0.8V) when many devices would stop functioning at higher voltages (1.2-1.3V for AA batteries).
- Limited Resolution: The simple analog display doesn’t provide fine gradations between “good” and “replace,” making it difficult to precisely determine remaining battery life.
Value Proposition
The BT-168’s primary appeal is its value proposition – a functional battery testing solution at a very economical price point. Users consistently acknowledge the quality limitations while appreciating what they received for the price.
As one user stated: “For $5 it is fine, but it could be improved on with some minor adjustments.”
The inclusion of two testers in one package enhances the value, allowing placement in multiple locations or sharing with family members. The fact that the tester requires no batteries of its own for operation also contributes to its long-term value.
