What is the average battery life of an NES cartridge?

Question

How many years does an NES cartridge battery last?

What? You mean they are battery driven and loose all savegames when the battery dies? Oo Does that only affect the savegames or will it make the whole game unplayable? — Dave, Jul 08 '10 at 10:37
Someone oughtta figure out a way to replace/recharge those, otherwise my collection is going to devalue seriously right before they become serious collectors items :-p — Ritwik Bose, Jul 12 '10 at 01:47
@Mechko: they've been replacing them for years: http://www.the9thkey.com/games/Nesbatt.htm — MGOwen, Sep 02 '10 at 05:31

According to this page, the batteries last 15-20 years.

Wow. Truly impressive quality, considering 5-10 years wouldn't have hurt their sales in the slightest. – MGOwen Sep 02 '10 at 05:32

While batteries do eventually die, only save games are affected by a dead battery. At least that's the way it works on my gemfire game. – user286231 Jan 27 '22 at 21:13
