Q: Does the BT-168 battery tester need its own batteries to operate?
A: No — the BT-168 is completely self-powered. It draws the small amount of current it needs directly from the battery being tested, so you never need to install or charge batteries in the tester itself.
Q: How do I read the results on the BT-168?
A: Simply place your battery into the correct terminal and the analog needle will deflect across a color-coded scale. A reading in the green zone means the battery is Good, yellow indicates Low charge, and red means the battery is Dead and should be replaced.
Q: Is the BT-168 battery tester suitable for testing rechargeable batteries?
A: Yes, the BT-168 can check the current voltage of rechargeable batteries (NiMH/NiCd) in standard sizes such as AA, AAA, C, and D, giving you a quick indication of whether they hold a charge. For precise mAh capacity testing, a dedicated battery analyzer would be recommended.
