Black Olive Battery Tester Universal Battery Checker For AA AAA C D 9V 1.5V Button Cell Batteries (Model: BT-168), Battery Powered, Black

Value for money. Amazing product. Very accurate readings.

I recently purchased the Battery Tester Universal Battery Checker for ₹275, and it has proven to be a great value for the price. It efficiently checks various battery types, including AA, AAA, C, D, 9V, and button cells, making it a versatile tool for any household. While I wasn't expecting top-notch build quality at this price point, it gets the job done effectively. The design is simple, and the readings are clear, allowing me to quickly identify which batteries still have life in them. Overall, if you're looking for an affordable and functional battery tester, the BT-168 is a worthwhile investment. Just keep in mind that it's not built like a premium product, but it certainly serves its purpose well.

A very useful gadget for today as most toys and household equipments work on batteries.

The main reason i bought this to utilize the battery to the fullest without being thrown underutliized to recycle market. Love it and works gr8!!! Review on 11th Oct 2025 It is behaving weird and one of the point got rusted because of which it is working sometimes and not working sometimes. Even while using it less and inspite of saving it from water, reducing 2 stars.

Took the decision in march to move away from Alkaline batteries - which are prone to leakages as well as has more harmful chemicals - and have started using rechargeable batteries, from remotes to toys, mouse etc. Note that I have used only with AA and AAA batteries. With this tool in hand, I have benefited in the following ways: 1. It is really easy to check if batteries have really run out of juice. Like in toys, if a couple of batteries are down on charge and the other 2 are good, you can just replace the drained out ones. 2. My Panasonic Eneloop CC61N charger is not auto cutting off after a recharge is done. As an example, for a AA battery with 1900 mAh, the specified charging time is 10 hours. But even after charging for 20 hours with SmartCell rechargeable 800mAh batteries, the charger did not auto cutoff. So I was unsure if the charge is over. With this tool in hand, I now just check the battery health after 3 to 4 hours of charging. And if it looks good, I stop charging. 3. It is certainly accurate as you can see from the pics with different battries. 4.value for money for sure. Certainly makes like easier, even with normal alkaline batteries, to decide if we can't use it anymore.

Form factor is not that convenient to use. And is overpriced. I found the similar product in local market for half the price. But it works so worth it

If you are you looking for a no-nonsense, frequent-usage, reliable tester for all the various little batteries in your home, then look no further, this is the gadget to buy. It works well on 9v batteries (rectangle type) and 1.5v batteries (AA, AAA and button cell types), and is quite intuitive and easy in use as well. Price is affordable, as this tester does not need a separate battery to use (unlike old battery tester I had, which did require battery to be plugged in, in order to operate the tester). This battery tester shows/uses 2 meters, a bigger meter for AA, AAA and 9v battery, and a small meter for button cell batteries. Highly recommended purchase for every home. Thanks to seller and Amazon for safe packaging and quick delivery.

Poor quality. Replacement requested not arrived till date even after 2 monthss

This is a good product. I lost the first one and purchased it again to replace it. D-Fantix Battery Tester has been working very accurately for me and it’s great knowing how much juice is left in a battery or if it’s dead. I really like this battery tester!
