B/c what's vented is hydrogen, which together with oxygen is explosive.
a vented battery is vented and the regular battery is regular

Under normal use, it is very unlikely that a 1.5v dry cell will explode. However, trying to charge a non-rechargeable battery, can make it explode. The charging current causes gas to form in the electrolyte, which puts pressure on the case, which is usually non-vented. The increased pressure can cause the case to explode. There have been chargers made, that will increase the life of single use cells, by charging them. These have a very small charging current, with long charge time, that does not allow gasses to build up. Trying to fast charge a rechargeable battery will also make it explode, for the same reasons. It is best to use only the charger specified for use with the type of battery. The charge currents (and even temperature monitoring) are built into intelligent chargers, to give the optimum charge without fear of explosion.
Because the Miata battery is enclosed and in the trunk, and because the trunk has large air tunnels directly into the cabin, a sealed battery is necessary. The most common Miata battery replacements are not too expensive, and have small tube connections that allow the gasses to be vented outside of the car. Visit WestCoBattery.com for online ordering, they are the most trusted source for Miata-sized batteries.
UNder the back seat, push seat bench back toward rear of car and pull up. Replace only with a vented battery. Dont cheap out on a non-vented one.
