KONNWEI KW510 Powerful 3 in 1 Multifunctional Car Battery Charger, Repair and Test Tool for All Types 12V Lead-acid Batteries
KONNWEI KW510 Battery Tester adopts the state-of-the-art conductance testing technology in the world to easily, quickly and accurately measure the actual cold cranking amps capability of the vehicle starting battery, healthy state of the battery itself, and common fault of the vehicle starting system and charging system. With a wide testing range from 100 -2000CCA compatible with regular flooded, AGM flat plate, AGM spiral, or gel batteries. Covers most of the battery rating standards like CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, etc.
WARNING:
The battery cca tester never discharges or drain the battery.
- If there are abnormal test results, maybe your battery is overcharged or incompletely charged. So the battery will be damaged or its life will be greatly shortened, then you can take action to deal with this issue.
Why do you need to know battery conditions (Good or Recharge)?
Know the battery status in advance to prevent the annoying battery failure situations.
Plug and play--input the rated battery capacity, KW510 will start analyzing the battery's CCA value, charge (%), voltage (v), internal resistance (O), rated CCA, battery healthy (%) and display the test result on screen within seconds.
- Provide 5 kinds of professional advice accordingly:
- GOOD BATTERY: The battery is without any problem, use it without worries!
- GOOD, RECHARGE: Good battery but low current, recharge before using.
- REPLACE: The battery is already or near to reach the end of the using life, please replace the battery.
- BAD CELL, REPLACE: Battery interior damaged, bad cell or short circuit, replace the battery.
- CHARGE-RETEST: Unstable battery shall be recharged and retested to avoid error.
ACCURATE RESULTS
High precision amplifier and calibrated by professional instruments give you the reliable results in seconds!
CRANKING & CHARGING TEST
CRANKING TEST : Analyzes the actual cranking voltage and the cranking time to help you quickly figure out the whole state of the starting system;
CHARGING TEST : Test different parts of charging system, including generator, rectifier, rectifier diode, and so on for a reliable charging volt value.
CONVENIENT TESTING SITUATION
No matter the batteries in the vehicles or out of the vehicles, KW510 will finish its testing job excellently, pocketed size let you can bring it to anywhere you want.
- Input Voltage: 100-230V AC, 50-60Hz

- Output voltage: DC 13.8V
- Battery range: 12V 4Ah-100Ah
- Dimensions: 6.3” x 3.7” x 2.4”
- Item Weight: 1.43 pounds
FITS FOR MOST VEHICLES
Designed for testing and charging 12-volt lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries.
Compatible with all types of vehicles - charge and maintain cars, motorcycles, lawn mowers, ATVs, lawn tractors, trucks, SUVs, boats, PWCs, classic cars, and more.
- PACKAGE INCLUDES
- 1 x KW510 Smart Battery Charger
- 1 x Charging Cable
- 1 x User Manual
AUTOMATIC FAST CHARGING
Max output 12-volt 5-amp, input 100-230-volt, charge dead batteries as low as 2-volt.
Automatic monitoring of the entire charging process through a microprocessor-controlled program. Auto change into low current mode after fully charged.
ENHANCED PULSE REPAIR
Automatic sulfating and acid stratification detection, the advanced repair mode can repair and reverse the damaging effects when batteries are left uncharged for extended periods to improve battery performance and longevity. (Note: The pulse repair function can only be used when the car battery is disconnected from the car.)
MULTIPLE PROTECTION
Short circuit / Overcurrent protection / Overheat protection / Fireproof material / Low pressure protection / Overpressure protection / Mislink protection / Electrification protection ) the charger will automatically turn off the power supply to protect the battery and charger.
