Safety is always most important factor of a product.
LILEAD Battery Spirit/ battery maintainer charger is DC to DC, input is 5V or 9V (QC charge), while traditonal 12V battery maintainer charger is AC to DC, input is 110V or 220V. LILEAD Battery Spirit is much safer than traditional 12V battery maintainer charger.
LILEAD Battery Spirit/ battery maintainer charger, it's not only small, but also intelligent.
LILEAD Battery Spirit/ battery maintainer charger have 6 stage charging steps, including:
Soft Start——Battery diagnosis, spark proof, reverse connection proof & short circuit proof.
Battery Activation—— activate weak battery which volt less than 10.5V.
Fast Charge—— up to 12V 1.25A output.
Medium charge—— low charging current to lower charging heat, prevent battery sulfur output.
Absorption——constant 14.6V charge.
Maintenance——can maintain the battery for years.
With LILEAD Battery Spirit, batteries will always in its best condition.
Battery Spirit/ battery maintainer charger Application
6 Stage charging process | |
Stage 1: Soft start | Battery Spirit will diagnosis the battery status and prevent sparking when charging. |
Stage 2: Battery activation | If the battery voltage is 3V- 10.5V, Battery Spirit will activate the battery. |
Stage 3: Fast charge | If the battery voltage is more than 10.5V, Battery Spirit will start a fast charge, max current 1.25A. |
Stage 4: Medium charge | In order to lower battery Sulphur/ gases output, Battery Spirit will change from fast charge into medium charge. |
Stage 3 and Stage 4 will repeat until Stage 5. | |
Stage 5: Absorption | When the battery voltage reaches 14.6 Volts, Battery Spirit will charge the battery at a constant voltage, to ensure the battery is 100% fully charged. |
Stage 6:Maintenance | Once the battery is fully charged, Battery Spirit will change into maintenance stage automatically, ensuring proper battery performance. |
