🔋 Panasonic CR2450 Button Battery (5PCS)
I ordered this set because I trust Panasonic when it comes to electronics, and I needed reliable CR2450s for a couple of remotes and a bike computer. These are marketed as high-quality, long-lasting 600mAh lithium coin cells — definitely what I was looking for.
Delivery was surprisingly quick — around 13 days to the U.S., which is faster than many other AliExpress packages I’ve ordered. Packaging was clean, and the batteries were sealed and dated with recent production, which immediately gave me some peace of mind.
Pros:
-
Excellent brand reputation
-
Fresh stock with long expiration
-
Each battery tested at 3.26V out of the box
-
Reliable in both high-drain and low-drain devices
Cons:
-
Slightly pricier than no-name options on AliExpress
-
No retail-style packaging — just a simple plastic sleeve
Compared to U.S. pricing, these cost me less than half of what I’d pay for genuine Panasonic CR2450s at stores like Walmart or Home Depot. Performance-wise, they’ve held up great — I’ve used two so far, and both are still going strong after weeks of daily use.
✔️ Met expectations? Yes, exceeded them slightly due to battery freshness.

🔋 5PCS Original Panasonic CR2450 Coin Cell
I wanted a second pack of name-brand batteries for other gadgets, so I got this original Panasonic CR2450 5-pack. The seller advertised these as authentic, high-capacity lithium cells — and honestly, they live up to that promise.
Shipping took a bit longer (about 16 days), but the batteries arrived intact, with solid voltage readings. I popped one into a body weight scale that had been finicky, and it started working instantly.
Pros:
-
Authentic Panasonic cells
-
Good shelf life (exp. 2029 on mine)
-
All five showed 3.2V+
Cons:
-
Again, no retail packaging
-
Slightly inconsistent voltage readings (though within normal range)
U.S. retail pricing is usually $3–5 per cell — I paid under $0.90 each here. Big win.
✔️ Met expectations? Yes — solid and dependable.

🔋 Rechargeable LIR2450 Batteries (5PCS)
These LIR2450 3.6V rechargeables caught my eye because I was tired of tossing out coin cells. I use button batteries a lot — mainly in LED bike lights, which eat through disposables fast.
These arrived in just under three weeks. Each one came individually packed in anti-static sleeves. They charge up to 4.2V and hold charge decently well. I’ve cycled two of them a few times, and they’re still performing well.
Pros:
-
Rechargeable, eco-friendly
-
High voltage output (ideal for bright LEDs)
-
Cost-effective long term
Cons:
-
Not ideal for all devices (some expect 3V, not 3.6V)
-
Capacity isn’t as high as advertised — maybe closer to 300–350mAh
Compared to non-rechargeables in the U.S., these are a steal. But you do need a compatible charger and must avoid using them in sensitive electronics.
✔️ Met expectations? Mostly — just be aware of voltage differences.

🔋 CR2450 600mAh Button Cells (5PCS)
I bought this generic set for backup use — things like holiday string lights and remotes that don’t see daily use. The claim is 600mAh, though I was skeptical.
Arrived in 17 days, loose-packed in bubble wrap. Voltage was 3.18–3.23V across all five. They’ve worked well so far — one in an LED Christmas ornament has lasted over a month.
Pros:
-
Inexpensive
-
Functional for light-duty use
-
Fresh charge on arrival
Cons:
-
May not last as long as name-brand options
-
No markings or branding on the cells
These were under $0.40 each. For low-demand use, they’re a solid budget choice.
✔️ Met expectations? Yes — especially given the price.

🔋 CR2450 Coin Cells for Car Remotes (5PCS)
Specifically marketed for car remotes and access cards, these batteries attracted me due to their focus on reliability under consistent load. I installed one in my spare Toyota fob.
Delivery time was excellent — 12 days. Packaging was basic but sufficient. Voltage tested 3.25V on all units.
Pros:
-
Stable under continuous use
-
Affordable and fresh
-
Easy to store and swap
Cons:
-
No branding
-
Only suited for basic electronics — not ideal for high-drain gadgets
Compared to car key battery prices in auto shops (where they can run $5+), this is a huge money-saver.
✔️ Met expectations? Definitely — got what I needed.

Flexible quantity options

🔋 2–10PCS CR2450 Lithium Button Battery
This listing offered mid-range packs (I chose the 5pcs) and claimed consistent 600mAh capacity. Used in a keychain flashlight and mini thermometer — both working great so far.

Pros:
-
Mid-capacity devices run just fine
-
Steady voltage
-
Very competitive price
Cons:
-

🔋 10PCS Mixed Panasonic Coin Batteries (CR2032, CR2450, etc.)
I liked the variety in this pack — having CR2032, CR2025, CR2450, and others in one place. It’s useful if you have a house full of random electronics.
These were definitely real Panasonic cells. Dates were fresh, and voltages strong (all 3.25V+). Arrived in 14 days.
Pros:
-
Real Panasonic, excellent quality
-
Broad compatibility
-
Best value for variety
Cons:
-
You don’t get to choose quantities per size

A few sizes I may never use
Still cheaper than buying 2–3 packs separately in the U.S.
✔️ Met expectations? Yes, highly recommend this one.

🔋 Eunicell CR2450 5-Pack
Wanted to try Eunicell since I’ve seen it pop up on Amazon. This 5-pack looked decent, so I added it to the order.
These showed 3.19–3.24V and worked in a wireless mouse and LED tealight candles. So far, no issues.
Pros:
-
Cheaper than Panasonic
-
Still functional for regular use
-
Comes in tidy strip packaging
Cons:
-
Not as long-lasting as Panasonic

Some minor voltage drop after a week
For low-cost devices, this is a fine alternative.
✔️ Met expectations? Yes.

🔋 Generic CR2032 and CR2450 Button Batteries (5PCS)
This mix-pack of generic lithium cells was a wildcard. I figured even if a few were duds, the price was worth it. Shockingly, all five worked.
Used in toys and a thermometer. Battery life seems average.
Pros:
-
Cheap
-
All functional
-
Decent initial voltage
Cons:
-
No guarantee of longevity
-
Inconsistent branding
U.S. store packs often include dead batteries at 4x the price.
✔️ Met expectations? Surprisingly yes.

🔋 Panasonic Bulk CR2450 (2–50PCS)
Ordered 10 of these — listed as Panasonic, and surprisingly, they seem genuine. All marked and dated 2029+, tested at 3.27V average.
Used in LED puck lights and a digital caliper — both running perfectly. Definitely better quality than most generics.
Pros:
-
Genuine Panasonic cells
-
Excellent charge retention
-
Ideal for both heavy and light use
Cons:
-
Slightly more expensive
-
Not the quickest delivery (18 days)
Still way cheaper than retail in the U.S. — I’d pay $30+ here for 10.
✔️ Met expectations? Exceeded them, honestly.

🛒 Overall Thoughts
I went into this order expecting a mixed bag — you never really know with AliExpress. But I came out seriously impressed. Every single battery I ordered arrived working and fresh, and many tested even better than expected. The Panasonic options were especially strong — better than what I’ve gotten from big-box stores.
Would I recommend these? Definitely — just choose based on your usage needs. If you want the best quality, go with name brands like Panasonic. If you need lots of batteries for light use, the generics are a great deal.
Will I buy again? No question — I’m already eyeing a bigger pack.
