Cross reference

Compare your existing battery model with this Discover battery. A model number or Ah rating alone does not confirm compatibility.

Before ordering, match voltage, case size, total installed height, terminal width or bolt size, polarity, charger and discharge duty. F1 is 4.8 mm; F2 is 6.3 mm. Standby, deep-cycle, high-rate, GEL and lithium batteries are not interchangeable based on Ah alone.
