ANCEL BT310 Car Battery Tester 12V 24V - Digital Automotive Alternator | Load Tester for Lead-Acid/AGM/Lithium-Ion (100-2000 CCA), Cranking & Charging Test for Car, Truck, Motorcycle, Boat, ATV

About this item

• Complete Battery, Cranking & Charging Test — Not sure whether the problem shows up before, during, or after engine startup? This battery tester checks all three stages: whether the battery still has enough power before you start, how it performs while the engine is cranking, and whether the charging system is properly putting power back into the battery once the engine is running. Together, these
• Know Your Battery Before the Next Start — Want to know if your battery is still ready for the next start? Enter the CCA number shown on the battery label, and ANCEL BT310 gives you a clear result—Good, Recharge, Retest, or Replace. You can quickly see whether to keep using the battery, charge it, check it again, or replace it, instead of trying to judge the battery from voltage alone or waiting un
• Know If the Battery Is Behind a Slow Start — When the engine starts turning over more slowly, is the battery really the problem? This battery analyzer checks how far the battery voltage drops and how long the cranking process lasts, with cranking time measured down to the millisecond. The results show how the battery performs when starting demand is highest, helping you see whether the battery is
• Confirm the Battery Is Recharging Properly — Battery charged up but keeps running low again? As a battery and alternator tester, the product checks whether the battery is being properly recharged once the engine is running. Charging that is too low, too high, or unstable becomes easier to identify, helping you see whether the problem may be coming from the charging system instead of the battery it
• Narrow Down Intermittent Voltage Issues — Voltage can change quickly during starting and charging, and one reading may miss brief abnormalities. The tool displays those changes as a clear waveform, making short voltage drops, spikes, and other unusual changes easier to notice. Instead of relying on a single number, you can follow how voltage behaves throughout the starting and charging process, gi
• Cover More 12V & 24V Batteries with One Tester — Need one tester for both everyday vehicles and heavier equipment? This 12V & 24V battery tester supports batteries rated 100–2000 CCA. Its 12V coverage fits a wide range of cars, SUVs, pickups, and other everyday vehicles, while 24V support extends testing to compatible commercial vehicles, heavy equipment, agricultural machinery, and more. It suppo
• Simple Checks, Clear Results, Added Protection — BT310 powers directly from the battery, while the backlit display and Data Review keep results easy to read and review. Unlike a traditional car battery load tester that pulls a heavy load from the battery, BT310 uses conductance testing with less strain on the battery. Reverse-polarity, short-circuit, over-voltage, and over-temperature protection a
