Best Bang for the...
Posted by Craig Dailey on Jan 10th 2026
The good ole standby "Chocolate" LG HG2 batteries are the best. Excellent quality, good durability, and last an exceptionally long time. Best of all, they are reasonably priced! Pretty decent shipping times too.

Works fine for a reasonable cost. I've used batteries costing 3x these that did not last any longer on a charge.

Tried these batteries based on recommendation for use for my device, but the battery-life per charge is significantly less than my current batteries, perhaps the ones I received were old or defective?

Posted by JT on May 25th 2025
Excellent batteries, and that's why I ordered 4. Ordered a mod, 2 tanks, spare coils, and a charger. Placed order in December. Finally got around to opening the box this April. Batteries were on the invoice and paid for, BUT NOT IN THE BOX. My bad for waiting so long, but also disappointed that CV shorted me

Product received was not the product advertised and sold. Refund, yes. But also lost money due to return shipping due to FALSE ADVERTISING.

Posted by Robert Lawhon on Apr 30th 2025
To preface: i want to make clear that this is a positive review.
So I received the item very quickly, and popped it in my mod. It had around 30% so I ran it until it hit 5%, then plugged up my mod. Left it plugged up for about an hour went back, and it read 1%. So over the next 2 days I tried several ways to charge it, and it just wouldn't take one. I emailed the company, and they got me taken care of. Absolutely no questions asked. The only reason I gave 4 stars is for the slight inconvenience of having to wait for another to ship. Everything about my interactions with this company was 10/5 stars. They really took care of me, they were fast and friendly. I will definitely use them again! -
Authentic LG battery?
Posted by Arnold Espiritu on Feb 19th 2025
I ordered 4 of these batteries, 2 of them are not holding a charge. Charging time are extremely different from each other (25 minutes to 2hours).

Posted by Marc McPherson on Jan 20th 2025
These batteries are 2 grams light. After putting them through test, the test show that these are only 2600 mah and NOT the 3000 mha as advertised.

Posted by Jerry Jean on Jan 11th 2025
These work really great. I've got pairs that have been charging and working fine for at least 8 years. I never let them get below 1/2 charge and charge them on an Xtar charger. They've just never let me down.
And the CUSTOMER SERVICE at Central Vapors ROCKS! Good people here! -

New, but are they....?
Posted by James Peterson on Mar 4th 2024
My pervious set of batteries that are at least 2 years older than these newest purchased ones hold a charge for longer. Running the same wattage on the same mod, same coils, tank and everything.

As advertised. Had to cycle through full charge a couple of times to reach full capacity.
