That's quite possible, things happen even when the saber just sit there.
Some people forget and leave batteries in sabers which alkaline batteries are more prone to rupture due to them discharging slowly over time while installed in electronics that aren't being used which will build pressure that ruptures the seals at the ends of the battery or the outer canister
