1) Many people say this, but 100 people not having a problem with a consumer product has no information. Two people having the same problem has tons of information.
2) NiMH are much lighter and are what should always be used.
3) Put strips of black electrical tape under batteries and on cover until you can just get the twist lock closed to really hold batteries in place.
4) Running GPS on 12 V eliminates any battery draw and therefore arcing even if they do vibrate. The 60 have known problem with internal battery connection that gets dirty from constant arcing and finally fails.
