US Portable Super Rechargeable 6800mAh 12v DC Li-ion Battery Pack

*

When I bought my used YouKits HB-1B, the internal battery was not recharging properly. I had read that using an internal battery could be harmful to the circuit board of the HB-1B over time, so I decided to try a different external battery rather than try to figure out what was going on with the original.

Today I'm trying out a new rechargeable li-ion 6800mAh 12v DC battery pack. So far it works great. It doesn't cause the type of notable interference that plugging the transceiver into the wall outlet does.

At 6:35am I started out with 11.1v power input, after a full night of charging. At 7:35am I'm getting 11.0v. My plan today is see how long it takes for the battery to run down to 9v (while listening only), which is the low end of the suggested input power range for this transceiver.

I've been listening to a constant stream of Morse signals on various frequencies. Reception on the HB-1B is great, mostly because of the filter. One of the really great things about this little QRP rig is that in addition to the CW that it transmits and receives, it can also receive USB/LSB voice.

We'll see how long this battery lasts. I'll update the hourly voltage readings below. Today I'm just listening, as I don't yet have my dipole set up at the new QTH. I'm looking forward to getting that set up and to transmitting soon.

Voltage Readings - Listening Only:

6:35am - 11.1v

7:35am - 11.0v

8:35am - 11.0v

8:47am - 10.9v / 11.0v

9:35am - 10.9v / 11.0v

9:41am 10.9v

10:35am 10.9v

3:35pm 10.8v

7:35pm 10.5v

9:35pm 10.4v

10:35pm 10.4v

11:00pm 10.3v

Needless to say... I don't think I'll ever be in a situation where I'll ever want to simply listen for more than 16 hours at one sitting. So, the next test will be to try some transmitting and see how well the battery does. I'm very happy with this setup. I might have to buy a second of these batteries for back-up on extended hiking trips in the mountains.

UPDATE: 30 Nov, 2015

I had thought that the battery was fully charged when I received it in the mail, but I was wrong. Something that you might not expect with this battery is that you turn it on when you're charging it. If it is not fully charged, the indicator on the plug will turn red. When the battery is fully charged, the indicator light will turn green. The light on the battery remains blue at all times. With a (now) fully charged battery, the transceiver now shows an input power of 12.9v. Plenty of long-lasting power for future radio outings.
