The iMax modeling charger is
The iMax modeling charger is not even close to being the Hybrid Automotive one. Those modeling chargers can't charge at low current and aren't useful for hybrid battery reconditioning. Everything looks good and working until the so-called reconditioned battery is installed on car and used with a 100 amp charge-discharge.
Since 2020 I've successfully rebuilt and reconditioned dozens of Toyota hybrid batteries with Hybrid Automotive charger.
Until 2020 i've played around with modeling chargers, wasting my time until i got stuck with 2 batteries that were throwing P0A80 code.
The Hybrid Automotive charger uses Chinese voltmeters which lie, initially at a few volts and now at 30 volts after a few years of use. The charger shows 240 volts, but in fact 230 or less. I think this is the number one reason why customers have not been able to restore their batteries with this charger.
