Lead acid batteries have more negative plates than positive due to the way they are made. The negative plates are made of lead oxide, while the positive plates are made of pure lead. The lead oxide is heavier than the lead, so it takes up more space on the plate. That's why there are more negative plates in a lead acid battery.
