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

Good battery tester. Works great. Easy to use.

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.

very useful product... easy to use even for a layman

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.

Much needed thing for checking batteries

Works but cheap quality

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.

very tough to fit any battery aa or aaa in order to get the contacts connected. Damages the battery , the actual product and how it is marketed as very easy to use is a big disappointment.

In the one week that I owned it, it works as promised and easy to use. Inexpensive and functional.
