LG MJ1 INR 18650 3500mAh 3.7V High-Drain 5A Lithium Ion (Li-ion) Protected Button Top Battery - Bulk

More Juice Than Advertised

"I just received a handful of LG MJ1 INR Button top 18650 batteries I ordered from Battery Junction. They're rated for 3500 mAh. I only had the chance to drain two of the seven I bought down to "zero" before recharging them in my multi-cell charger. My charger tells you the standard stuff about each battery in a slot: voltage, % charged, mAh amount charged to, temperature, etc. One of the LG batteries I got charged to 3800 mAh and the other one charged to 3900 mAh. Quite a bargain when you consider that my flashlight's manufacturer's batteries rated for 3500 mAh charge to 3500 mAh at 3X the cost of these batteries from Battery Junction. Good procurement job, folks. Grazie,"

CAUTION - This cell is generically wrapped

"Please be aware, this cell has a button top added after the LG production, resulting in two outer wraps (a green one that looks as expected with finished cells and a generic clear one over it). There is a note on the page that warns as such, however, it doesn't show up on the mobile site unless you expand the description and note. The packaging does not include a warning/indication beyond the standard disclaimer and the plastic wrap appears to be part of the shipping material, with a generic sticker affixed. It looks exactly like the generic wrap that must be removed from AA/AAA battery pairs when shipped with remotes or other electronic devices. Don't make my mistake and waste ~$16."

Perfect Battery for Solar Lights

"The LG MJ1 is one of the best high‑capacity 18650 cells I’ve used for low‑drain devices. I installed it in my solar string lights, and the difference was immediate. The old battery would fade out around 10 PM, but this MJ1 keeps the lights bright and steady all night — I’ve seen them still running at 4 AM. Huge upgrade over the generic cells that come with most solar panels. Highly recommended."

"Exactly what I needed thanks!"

Larger diameter

"This battery had excellent reviews. Si I purchased them for my Olight tactical flashlights. Sadly, the button-top 18650’s will not fit. They are too wide. You ARE NOT supposed to pull off the plastic cover from the battery. But I did pull off the sticker hoping to minimize its diameter. Still a no-go. I can still use the batteries in another piece of equipment. But it was a failure for my initial purpose of buying them for my flashlights. Beware. They are a larger diameter with the plastic covering."

Bright light!

"This 18625 battery replaces the 3 AAA battery's that came with my tactical flashlite and is way brighter and lasts 4 times as long. Try it you'll never go back to AAAs"

What's the underlying reason for a bad review 🤔

"I can't recall ever writing a bad review for any order because most companies are more than willing to work out any issues with a reasonable person. With that being said, my first order with Battery Junction was flawless 😍. Maybe the bad reviewers should try a more civil approach 🤔. Keep up the good work."
