But the cheap AA batteries are very prone to leaking. Especially the older one. The newer ones (last couple of years) seem to be much better, but we will see when their shelf life begins to expire.
Just a helpful FYI:
Ray-O-Vac Alkalaine batteries are the WORST POS AA batteries (and C, D, AAA) that you can buy. Do NOT put these in ANY of your game equipment -- even if off the main board on an isolated plastic holder.
These batteries, even stored around 60 degres, seem to begin leaking about 1-2 years before their expiration date even without being used.
I've purchased numerous batteries from all the major manufacturers (Panasonic, Energizer, Duracel, RayOVac), plus store brand ones (NorthTech, AC Delco) and within a year of expiration about 20% of the RayOVac ones have begun leaking, and by their expiration date, about 40% are leaking.
I rarely ever have a good brand (Panasonic/Energizer/Duracell) leak, and if they do, it's 5-10 years after their expiration date.
The leaking can either be outright clear goo, or a white crystal structure expanding the side and base of the battery.
I've ruined a few remote controls and kid's toys with these and will never buy them again. Most were purchased cheap or free after rebate from Menards up here in the midwest over the course of the last 10 years. Even their store brand NorthTech ones hold up about 4 times as well (one fourth the number of leaks by the expiration date).
