Uprated Battery

More expensive batteries are available with larger capacity and cold cranking current. Battery vendors typically brand these as "Gold" or "Plus" batteries.

An uprated battery will have the same dimensions as above, though capacity is upgraded to about 410CCA and weight increases to about 12.8kg.

Larger Battery

A larger battery which fits into KE3x/5x/7x is SuperCharge part number MF52 Gold, with the following specs:

  • Width: 237mm (horizontal)
  • Depth: 171mm (horizontal)
  • Height: 182mm (vertical)
  • Terminal Height: 208mm
  • Wet Weight: 15.7kg

You'll need to buy a larger 18cm/7" battery hold down clamp, as the original 14cm/15cm clamp will not fit the larger battery.
