Reviews

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."

LG MJ1 INR 18650 3500mAh 3. 7V

"Good Quality and quick shipping. Would recommend and purchase again."

— Timothy S. (5/5)

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."

— VERNER R. (5/5)

This battery was perfect!

"Exactly what I needed thanks!"

— Richard B. (5/5)

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."

— Raymond M. (4/5)

very good battery

"battery charged just fine, appears to be better quality than original equipment battery"

— james M. (5/5)

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"

— MAX S. (5/5)

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."

— Andy B. (5/5)

Absolutely awesome Batteries

"I ordered These last week,came yesterday well packed. I took photos of the 4 of them in the charger when done and all of them were above 3600 mah!!All my Convoy and Wurkkos,Sofirn,top of the line Ultrafire and top of the line Trustfire lights are beyond performance specs. All my lights rated at 1800 and at 2000 lumen are all safely pushing 2100 to over 2200 lumens. These are going to be my go batteries from now on. Got these before for my MTN bike lights and same level of quality which is why I got them again."

— Ranger 1. (5/5)

No complaints

"Website was good. Shipping was faster than expected and batteries are performing as intended"

— Lorraine O. (5/5)

Q&A

The MSDS (SDS) is almost 10 years old, I know there is a newer one for this cell, do you have it?
We will get an updated one and update the listing. This has now been updated with a more current document.
I am going to rebuild a Lectric XP 3.0 Ebike battery. The batteries in the current pack are 2300 MAH 10 amp draw. Do you think these would be a good replacement which would provide more range?
We do not build battery packs so really can't advise you. The batteries you referred in the question are a higher capacity than the ones you mention in your question so would give a longer run time. Other than that, you would need to talk to someone who knows about pack building for additional questions or information since we do not know enough about pack building to offer guidance.
Would these be suitable to rebuild a m12 battery pack? Thank you.
We do not build battery packs so would not be able to answer your question.
