Frequently Asked Questions
What's the difference between the AD42B19R and AD42B19L?
The only difference is terminal position. The AD42B19R has the positive terminal on the right; the AD42B19L has it on the left. Both share the same JIS B19 case size (187 × 127 × 226mm), 360 CCA and 24-month warranty. They are not interchangeable — fitting the wrong layout can cause cable-reach problems or reversed polarity.
