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?
