Q 1. What battery types is the SIP STARTMASTER DSC350B compatible with?

A. The DSC350B supports all 12v and 24v lead acid chemistries — including WET, MF, EFB, GEL, AGM and CA types — as well as 12v 4-cell Lithium-Ion LiFePO4 batteries. Battery auto-detect identifies whether the connected battery is 12v or 24v before beginning any charging or boosting cycle.

Q 2. What is the maximum start current and battery capacity of the DSC350B?

A. The STARTMASTER DSC350B delivers a maximum start current of 400A on a fully discharged battery and 300A on a medium-charged battery, with a 200A fuse fitted. It supports battery capacities up to 350Ah.

Q 3. What are the charging current and boost charging specifications?

A. The DSC350B charges at between 5A and 20A on continuous input (1,400W / 5A). Boost charging current reaches 35A for a maximum of five minutes. For jump-start operation, the unit draws 7.5kW / 32A for up to five seconds.

Q 4. What power supply does the SIP 03586 require, and what plug is recommended?

A. The unit operates on a 230v 50Hz input supply. For charging use, a 230v 13A plug is recommended; for jump-start use, a 230v 32A plug is recommended. Neither plug is supplied with the unit.

Q 5. What applications is the STARTMASTER DSC350B designed for?

A. It is designed for battery charging and boost-start applications in automotive, agricultural and engineering workshop environments, and is suitable for charging commercial vehicle batteries.

Q 6. What safety features does the DSC350B include?

A. Built-in safety features include an anti-spark system to prevent sparks when connecting the clamps to battery terminals, reverse polarity protection, overcharge protection, and an overheat alarm. The overheat alarm automatically restarts the unit once it has cooled.

Q 7. What does the 10-step automatic charging cycle do?

A. The intelligent microprocessor runs a 10-step cycle that automatically diagnoses battery condition and voltage before beginning a charging cycle. Low 1v detection capability improves the chances of recovering batteries that are unwilling to accept a charge, and an Alternator Test mode indicates alternator working condition before charging or boosting is applied.

Q 8. What warranty does the SIP STARTMASTER DSC350B carry?

A. The DSC350B is covered by the SIP 2-Year Standard Silver Warranty.

Q 9. How long does delivery take?

A. Standard UK mainland delivery is 3–5 working days. Next-day delivery is available on most products and will appear as an option at checkout where eligible.
