1. Polarity Check: Select batteries with reverse polarity (- / +) to match terminals of Sand-vik drilling rigs.
2. Mounting Space: Confirm the battery compartment fits the size 353×175×190 mm.
3. Parallel Connection: For dual-battery parallel setup, use batteries of the same model and batch.
4. Battery Type Selection:
   • General working conditions: Calcium-Calcium maintenance-free battery (low cost, minimal maintenance)
   • Frequent starting & deep cycle scenarios: AGM type (vibration-resistant, longer service life)

• Varta 6СТ100з SD: Reliable performance, 830A starting current, ideal for DL series
• Monbat 12HVR100C AGM: Carbon technology design, over 1200 cycles, excellent low-temperature performance
• SADA 6СТ-100Аз: Compliant with Asian standards, suitable for DD311 / DD321

The 6ST-100 (12V 100Ah) battery is a cost-effective alternative for starting and auxiliary power of Sand-vik DD/DL series drilling rigs. It features larger capacity and stronger starting current than the original 95Ah battery, with compatible dimensions and matched polarity, fully adaptable to harsh underground working environments.
