Designed to charge a battery and provide support for the battery during prolonged electronic diagnostic checks The Sealey BSCU170 is a fully automatic microprocessor controlled unit designed to both charge and provide support for the battery during prolonged electronic diagnostic checks. Up to 100Amp power supply maintains stable voltage under varying loads during major vehicle ECU reprogramming and diagnostic work. Recovery/Desulphation mode will recover a discharged battery (>2V) to almost 100% of its original capacity. 70A continuous output current or up to 100A maximum for up to three minutes as required. The “thermal runaway” protection and algorithms allow fast and safe charging. Designed for use with regular automotive, lead-acid, calcium, AGM/GEL and start-stop battery types. Once fully charged, the battery may be left connected to be automatically conditioned and maintained.
