Operates without batteries - Easy to read, the analog display pointer moves along the color-coded, calibrated scale to quickly identify "good" (green), "low" (yellow), and "replace/charge" (red) battery status. No batteries required. It is activated by the battery being checked. 
Perfect for home use - This excellent small battery teer can tell you whether the battery is in good condition, insufficient, or needs to be replaced. For those who frequently use regular batteries or rechargeable batteries, this is a must-buy item. 
Save battery power - You can simply test the battery voltage to determine whether the battery capacity is low or high. It does not directly and precisely measure the battery capacity. This will prevent us from wasting perfect batteries by discarding good ones.
