The YTX7L-BS column gives the specifications from Yuasa, the brand that created the battery code; the other column gives those of the battery sold by Satkit. Capacity is always compared using the same hour rate, and starting current using the same standard.

What does YTX7L-BS mean?

  • Y: Yuasa, which created this naming system. Other manufacturers change only this letter (GS uses GTX, Exide uses ETX and BS Battery uses BTX), keeping the rest the same.
  • TX: the maintenance-free AGM series.
  • 7: a size and power index, not the amp-hours: the YTX7L-BS has a capacity of 6 Ah at the 10-hour rate.
  • L: reversed polarity, with the positive terminal on the right when you face the label.
  • -BS: the original battery is supplied dry with an acid bottle (bottle supplied), so it must be filled before fitting.
