Battery failure is one of the most common causes for sensor or instrument failure. The BAT-200 Battery Tester indicates the amount of charge remaining in standard and rechargeable batteries. The analog display needle moves on a color-coded, calibrated scale to quickly identify "good" (green), "low" (yellow), and "replace/recharge" (red) battery status. The BAT-200 tests 9V, AA, AAA, C, D and 1.5V Button Type batteries. Tester does not require any internal batteries to operate.

Battery voltage decreases as the battery is discharged. Slightly used batteries may show close to full voltage. This means as long as the battery is not in the yellow or red field (indication of low voltage); the battery does not need to be replaced.
For testing batteries used in high current/high load situations such as digital cameras, the battery may need to be replaced when tester indicates battery charge is in the low end of the “good” range (near yellow field). These batteries can still be used in low load applications such as in remote controls.
Rechargeable Batteries are typically 1.2V when fully charged versus 1.5V for normal alkaline batteries, but they have a higher battery capacity (mAh). Because the BAT-200 tests for voltage, these batteries are still usable when the tester indicates green or yellow fields. When testing batteries, ensure the negative terminal is on top (battery upside down). For button batteries (1.5V only), the negative terminal is on top (look on printing on top of battery to verify terminals and 1.5V voltage).
