Yuasa YTX20-BS 12V Maintenance Free Battery
Capacity Ah (20-HR): 18.9 CCA @ -18C: 270


VRLA (Valve Regulated Lead Acid) means a battery that's perfect for people who have better things to do than battery maintenance! Our permanently sealed VRLA battery never needs refilling; however, it still needs periodic charging. Ideal for motorcycles, scooters, ATVs, riding mowers and personal watercraft.


  • Spill-proof design means virtually no possibility of leaks
  • Advanced lead-calcium technology pumps up starting power
  • Sulphation retardant dramatically reduces battery-killing plate sulphation
  • Long lasting which means Yuas's Maintenance Free batteries will last up to three times longer than conventional batteries
  • Exceptional resistance to vibration makes Yuasa the most reliable battery on the market today
  • And, VRLA batteries hold voltage longer and need less charging in standby or storage mode
