Q 1. What battery types and voltages is the CHARGESTAR D40 compatible with?

A. The SIP CHARGESTAR D40 is designed to charge all types of 12v and 24v lead acid batteries, including WET, MF, EFB, GEL and AGM chemistries. It supports battery capacities of up to 550Ah at 12v and 300Ah at 24v.

Q 2. What charging current settings are available on the CHARGESTAR D40?

A. At 12v, the unit offers four current settings: 2A, 10A, 20A and 40A. At 24v, three settings are available: 5A, 10A and 20A. A Boost — Fast Charge mode delivers five minutes of continuous 40A charge for rapid top-ups.

Q 3. How does the automatic charging cycle work on the CHARGESTAR D40?

A. The CHARGESTAR D40 uses an intelligent microprocessor to govern an 8-step fully automatic charging cycle. It diagnoses battery condition and voltage before commencing the charge. Once the battery reaches full capacity, charging stops automatically and a control panel indicator is displayed.

Q 4. What happens if the battery voltage is very low?

A. If the detected voltage is less than 3v, the unit will prevent charging, as battery recovery at that level is not possible. This protects both the charger and the user from attempting to charge a battery that is beyond recovery.

Q 5. What safety features are built into the CHARGESTAR D40?

A. The unit includes an anti-spark system to prevent sparks when connecting clips to battery terminals, reverse polarity protection, overcharge protection, and an overheat alarm. If the unit overheats, it will stop automatically and restart once it has cooled sufficiently.

Q 6. Can the CHARGESTAR D40 be used to check alternator health?

A. Yes — the unit features an Altn Check mode that indicates alternator health and performance. This function is available on 12v vehicles only.

Q 7. What is the input supply requirement and operating temperature range for the CHARGESTAR D40?

A. The charger requires a 220v–240v, 50–60Hz supply with a maximum draw of 750W and a 10A input fuse. It is rated for operation between 0°C and 40°C, and carries a protection level of IP20.

Q 8. What is included in the box with the SIP CHARGESTAR D40?

A. The unit is supplied with two 2-metre leads fitted with clip clamps.

Q 9. What warranty does this product come with?

A. The SIP CHARGESTAR D40 is backed by SIP's 2-Year Standard Silver Warranty.

Q 10. Can I ask questions about this product before ordering?

A. Yes — WhatsApp us on 07754 288583 with any questions about specifications, suitability, or compatibility.
