Sizes, not just amp-hours

A battery fits because of its box: length, width, height and which side the positive terminal is on. These are the 194 group sizes we work with: 36 JIS, 27 DIN and 131 two-wheeler.

Reading a JIS code

Performance class

Roughly tracks capacity and cranking current. Not a direct Ah figure.

Case class

Width and height. B is 129 mm wide, D is 173 mm. A different letter is a different box.

Length

Long side in centimetres. 20 means roughly 200 mm.

Terminal side

Positive post on the left, viewed from the terminal end. R is the mirror image.

JIS B20 case diagram: 38B20L has the positive post on the left and 38B20R on the right, viewed from the terminal end. The case is 197 mm long, 129 mm wide and about 227 mm high.

DIN codes work differently. The number is the capacity in amp-hours and the box is fixed at 175 mm wide; only the length changes: 207, 242, 278, 315 or 353 mm (L1 to L5). A low box is 175 mm tall instead of 190 mm.

JIS sizes

Fitted to most Indian, Japanese and Korean vehicles. Grouped by the box they share.

L and R are not interchangeable

38B20L and 38B20R are the same size and capacity. The only difference is which side the positive terminal sits on, and if it is the wrong side the cables will not reach. It is the most common wrong-battery mistake there is, and it is invisible on a spec sheet that lists only amp-hours.

We check the terminal layout against your vehicle at the counter before anything is fitted.
