Panasonic NCR18650-GA 3500mAh Button Top Li-ion Battery 2-Pack with XTAR MC2 USB Charger – High-Capacity Power Kit for High-Power Flashlights, Outdoor Gear

What's in This Bundle

• 2x Panasonic NCR18650GA, 3,450mAh, Button Top (unprotected)
• 1x XTAR MC2 dual-slot USB-C charger
• 1x USB-C charging cable (included with the charger)

A ready-to-go starter kit for anyone who needs two matched, genuine high-capacity 18650 cells and a compact way to charge them — no separate charger purchase, no guessing whether a charger you already own is a safe, appropriate match.

A note on Button Top GA cells: the market has two distinct versions sold as "NCR18650GA Button Top." The version in this bundle is an unprotected bare cell with a mechanically converted raised terminal — full 10A discharge capability, same internal cell as the Flat Top version. A separate, longer "Protected Button Top" version also exists elsewhere with a built-in PCB that caps discharge at 5A. If you've seen the GA advertised with a 5A limit, that's the protected variant, not what's in this listing.

This listing is for Button Top. Looking for Flat Top? Click here to buy: Panasonic NCR18650GA  Flat Top + XTAR MC2 Bundle.

Why This Pairing Makes Sense

The NCR18650GA is one of the most popular high-capacity 18650 cells on the market — strong energy density, a genuine 10A continuous discharge rating, and a long track record in flashlights, e-bikes, and general electronics packs. Button Top is the terminal type required by devices with spring-loaded battery contacts. Buying two cells together as a matched pair means you're starting with cells from a similar batch, which matters for anything that runs cells in series or expects consistent performance between them.

The XTAR MC2 pairs well here because it charges both slots at a full 1A simultaneously, with no current-splitting trade-off for using both bays at once — a safe, comfortable rate just under this cell's 1.475A standard charge current.

Panasonic NCR18650GA — Battery Specs

A note on wrap printing: due to regulatory changes in some markets, genuine GA cells are sometimes printed with their minimum capacity (3,300mAh) on the wrap rather than the 3,450mAh typical figure — the actual cell capacity hasn't changed, it's a labeling convention. Don't assume a cell printed "3300mAh" is a lower-capacity fake; check other authenticity markers (weight, lot code, seller sourcing) rather than the printed number alone.

XTAR MC2 — Charger Specs

A realistic note on charge time: the MC2's 1A per slot is just under this cell's 1.475A standard charge current — a safe, unhurried rate. Expect a full charge in roughly 4-4.5 hours, both cells at once.

Where the NCR18650GA Actually Fits

• High-capacity flashlights and headlamps — long runtime is the main draw of this cell
• E-bike and general electronics packs — a long-standing popular choice for runtime-focused builds
• Portable power and backup power applications where capacity matters more than burst current
• Goggles, radios, and similar low-to-moderate current gear

Not recommended for sub-ohm applications — this cell's 10A ceiling and energy-focused design make it a poor match for that use case specifically, even compared to other moderate-drain cells. If you need a vaping-focused cell, look at the Samsung 30Q or 25R instead.

Things Worth Knowing Before You Use This Kit

• This is an unprotected cell. The charger enforces its own voltage and current cutoffs, but your device still needs to handle discharge-side protection.
• Don't mix these cells with older ones you already own, even if they're also GA cells. Pairing cells from different ages or usage histories in a series/parallel setup can cause imbalanced charging over time.
• 10A is a real ceiling. Don't use these in devices that regularly demand more current than that — a dedicated high-drain cell is the safer choice for those applications.

Frequently Asked Questions

Is this Button Top version protected or unprotected? Unprotected. This is a bare cell with a mechanically converted raised terminal, retaining the full 10A discharge rating. A separate "Protected Button Top" version with a built-in PCB also exists on the market, capped at 5A due to the protection circuit — that's not what's included here.

Can this charger handle the GA's full capacity safely? Yes. The MC2's 1A per slot sits just under this cell's 1.475A standard charge current — a full charge takes roughly 4-4.5 hours, both cells at once.

Why does the wrap sometimes say 3300mAh instead of 3450mAh? Some regulatory labeling requirements call for printing the minimum rated capacity rather than the typical figure. The cell's actual capacity hasn't changed — it's a labeling convention, not a different or lower-capacity product.

Can I charge two different battery sizes at once? Yes — the MC2's two slots operate independently with automatic size and chemistry detection, so you could charge one 18650 and a differently-sized cell (like a 21700) at the same time if needed.

What does the "0V activation" feature do? It lets the charger attempt a slow, controlled charge on cells drained deep enough that a standard charger would refuse to recognize them at all. It won't save every over-discharged cell, but it can recover some that would otherwise be written off.
