yes the A's will leak in time, much less time than say the button types. which is why I believe in a prev thread before ( cant find it now) about batteries and MISB TFs most people here do remove the batteries ASAP, but for MISB collectors well. since they're not gonna open their collection anyways I guess they just let them leak in the long run..
