Yes, I am aware of that. It will happen to most remote controls which are not used for a long time but the batteries are still inside the slot. If the device (remote control) is frequently used, corrosion at the terminals which may lead to the device not functioning, it likely won't happen ie. leakage to the internal circuit boards of the device leading to damage.

Bought Panasonic Evolta to try out on my remote.

I am still testing the batteries on my amp remote as it seems fussy. Even with new batteries, with Eveready Heavy Duty cheap batteries, it will work for 1 minute, then later it won't work anymore and I need to remove the batteries from the slot and insert them back in, and it will work again. Then after 1-2 minutes the remote will stop working again. This is new batteries. Currently with GP Supercell it's working so far. IF it stops working again I'll get the Panasonic Evolta alkaline batteries in, but I need to receive the package first, ordered yesterday still in shipment.
