This tester is suitable for battery matching, battery performance testing, battery screening, assessment of battery condition and lifetime, etc. It can measure Lead acid, Li-ion (Lithium ion), LiPo (Lithium polymer), LiFePO4 (Lithium ion phosphate), Alkaline, Dry Cell battery, Nickel Metal Hydride (NiiMH), Nickel Cadmium (NiCd), Button Cell, etc.

It's widely used by the Solar, IPS, UPS industries, etc. This is a must have tool for the individuals/ companies who work with batteries.

Features:

• True 4-wire AC sinusoidal measurements effectively refrain the effects of test leads and contact resistance.
• Two function interfaces, battery sorting function.
• Built-in rechargeable battery can be charged via USB cable/ mobile phone charger. It has low power consumption + multiple power saving options.
• The test range is up to 200 ohms with a minimum resolution of 0.01 milliohms and less than 5 milliohms.
• Press HOLD to enable the ZR function to measure internal resistance as low as 0.30-0.50 milliohms.
• Handmade, the appearance of the right side is overly cautious.
• True four-wire 1KHz AC sinusoidal battery internal resistance meter ranges from .01 milli ohms to 200 ohm.
• It can measure Lead acid, Li-ion (Lithium ion), LiPo (Lithium polymer), LiFePO4 (Lithium ion phosphate), Alkaline, Dry Cell battery, Nickel Metal Hydride (NiiMH), Nickel Cadmium (NiCd), Button Cell, etc.
• The ZR function measures interneal resistance below 5 ohms more precisely.
