8 Charging Modes for Stable & Optimal Charging
Why your battery can’t get fully charged when it is cold or hot outside?
Why your lithium-ion batteries aren’t well-performed after the charging?
As you may notice, charging various batteries in different conditions and surroundings needs special care.
This automotive battery charger TORNADO4000 is tailored with advanced 8 manually selected modes, to guarantee optimal charging for your battery (view details in the image).
Avoid under-charging in cold weather even to 14°F (-10°C).
Avoid over-charging in hot weather up to 104°F (40°C).
Suitable for AGM batteries which are sensitive to overcharging.
Charge lithium-ion batteries correctly for excellent battery performance.
Offer precise charging to small capacity batteries (20AH-50AH).
Can even charge 12V aged, idle, damaged, stratified, or sulfated batteries.
10-Step Smart Charging, Microprocessor Controlled.
The built-in microprocessor in this car battery charger intelligently breaks the charging process into 10 routine steps. Each step is designed to maximize charging performance and help extend battery life:
Battery Analysis & Diagnosis – make a quick diagnosis; determine if the battery can hold a charge.
Battery Desulphation – break down the sulfates; optimize the charging.
Soft Start – minimize the startup currents; avoid the sudden voltage surges.
Battery Initialization – start charging with a gentle (soft) charge.
Battery Bulk Charge – begin the bulk charging to 80% of the battery’s capacity.
Absorption Mode – deliver small amounts of current when the charge level is 90%.
√Battery Recondition – check battery status, recover with a small current.
Battery Optimization – finalize charging, and bring the battery to maximum capacity.
Battery Float Charge – maintain the battery fully charged, without overcharging.
Battery Restart Charge – restart charging, when battery capacity is <85%.
Switching between modes is fully automatic and hands-free.
This 10-step charging process ensures that each battery gets the power it needs, and can be left 24/7 without overcharging or damage.
Wide Application
As an effective battery charger, TORNADO4000 has 4 Amp current output for charging 6 and 12-volt batteries, both lead-acid and lithium-ion, from 20Ah up to 120Ah, with an impressive range of applications from automotive to marine, power sport, RV, and deep-cycle batteries.
