Lithium ion batteries are good for 20 years.. I just found my original 3ds from 2011? And the battery is still giving 4-5 hours of playback.. and it's only $20 to replace
Graded and sealed Nintendo 3DS consoles, especially limited-edition Majora's Mask models, are commanding prices up to $1,500 on eBay, fueling anger among players already struggling with inflated costs for working handhelds. Critics warn that encasing unopened systems in acrylic traps aging lithium-ion batteries, raising safety concerns over potential swelling or leakage while rendering the devices unusable as game consoles.
