Review on 🔋 Upgrade 7-Stage Automotive Trickle Charger and Maintainer for Car Battery, Motorcycle, Lawn Mower, Truck, Lithium, Lead-Acid, LiFePO4 Battery - Luoges Car Battery Charger 12V 6A / 24V 3A (Red) by Antoine Cash

I was surprised by the versatility of chargers. The repair mode actually works as it brought the lawn mower battery back from the dead. Then immediately switched to the LifeP04 battery and it worked perfectly. The instructions are poor and obviously translated, but the charger is very basic. If you can't figure it out, don't use it.
