Replacement CR2032 3V button cell battery for Sega Dreamcast Lithium - 2 pack | Maxell

• 2× replacement CR2032 non-rechargeable 3V lithium button cells
• Restores internal clock/CMOS memory in the Sega Dreamcast
• Compatible with Dreamcast battery-holder mods using CR2032 cells
• Cost-effective replacement for expired, leaking or weak batteries
• Batteries only – requires a pre-installed CR2032 holder mod

If your Sega Dreamcast repeatedly asks for the date and time on startup, the internal clock battery has likely failed. This 2-pack of CR2032 lithium button cells offers a simple and effective way to restore the console’s real-time clock so it retains its settings while powered off.

NOTE: Your console must be modified with a coin battery holder mod to use these battery cells in your dreamcast.

Dreamcast consoles originally used a rechargeable ML-type cell. To safely use standard CR2032 batteries, you must have a battery-holder mod or compatible non-rechargeable setup installed. These replacement cells are intended for consoles that have already been modified to accept CR2032 batteries.

A fresh battery is recommended if the system loses its date/time, the original cell has leaked, or voltage drops below stable retention levels. This pack provides two new non-rechargeable cells for long-term reliability.

• CR2032 3V lithium non-rechargeable button cells
• Quantity: 2 batteries
• Requires Dreamcast battery-holder mod for safe use
• Not a direct drop-in replacement for the original rechargeable battery
• Store unused batteries in a cool, dry place

Q: My Dreamcast asks for the clock every time I turn it on. Will these batteries fix that?
Yes — this usually means the internal clock battery has died. If your console has a CR2032 holder mod installed, replacing the old cell with a fresh one will restore date/time retention.

Q: Do I need a battery holder or modification?
Yes. The Dreamcast’s original rechargeable cell is not directly compatible with standard CR2032 batteries. You must have a CR2032 holder modor or equivalent installed first.

Q: Does this include the holder or mod?
No — this listing provides the battery cells only. A pre-installed holder/mod is required.

• Risk of serious injury or death if swallowed — keep coin batteries away from children.
• Handle coin cells carefully to avoid short-circuiting.
• Disconnect the console from power before working inside it.
• Recycle old batteries at an authorised WEEE collection point.
