BL-8L  High Capacity
UV82 Series Battery
including UV82X, 82C, 82L & UV89

The BL-8L is a 3600 mAh battery designed specifically for the Baofeng/Pofung UV82 series transceiver.

Battery Capacity 3600 mAh
The standard BL-8 battery is a 7.4V 1800mAh, though many have been mislabeled as 7.4V 2800/3000/3350 mAh from the factory.
I have 2 standard batteries. One labeled 1800mAh, the other 2800mAh. They are both the exact size and weight.

The total weight of a standard BL-8 weighs 3.1oz (88mg). Regardless of the markings, this is an 1800mAh battery.  The BL-8L high capacity battery is 5.3oz (150mg) and 2.25" longer. The BL-8L is a true 3600 mAh battery.
The additional 2.25" to the length of the battery takes the total length to 6.9".  When standing vertically, the battery is stable, but a little top heavy. I personally find that a small price to pay.

Designing the case as longer rather than thicker allows it to utilize the standard CH-8 battery charger.  No alteration to the belt clip is necessary as the thickness is the same. 
The battery snaps on cleanly, and I didn't find the additional 2.2oz  objectionable. 
I did a side-by-side comparison using two same model UV82 radios with all software settings identical.  With both tuned to a constant signal (NOAA). Starting with both batteries fully charged, the radio shutdown time ratio was almost exactly 2 to 1.
When I run in radio in my vehicle, it fits nicely into the cup holder and the extra weight actually helps keep it in place when using a Spkr/Micr.
For all day events such as hiking, camping, Field Day, Hamfests, etc. or any time you just don't want to take the chance of depleting your battery, this would be an excellent choice.

This can be purchased at  BaofengTech
