In the market for an external battery

This was the battery I purchased just over a year ago, it was for the Elecraft KX3 as a back up battery for the times my internal batteries gave up the ghost. Unfortunately the battery will no longer hold a charge and it's only after a year and maybe 3 uses. I am now in the market for an external battery that I hope will not let me down after only being called on 3 times. Any ideas out there??

    Mike, I had exactly the same problem last week with the same type of battery. When I took it apart one of the cells was showing 0V. Apparently, the cells are recycled.

    LiPo batteries are better but still need careful handling. LiFe batteries offer the same benefits as LiPo but are very much less likely to catch fire, although they are a little heavier for the same capacity.

    I plan to get a LiFe battery as weight is not my most important criteria but these (and LiPo) do also need the correct type of charger.

    Like you I am looking for advice before I commit to a purchase.

    Simon, G0FCU.

    Good morning Simon, very interesting to hear that you found the cells to be recycled and that makes sense with the limited life time of the battery. I am going to do some looking into the LiFe batteries as well. Do email me when you find something that suits you.

    Hi Simon.

    See my blog post from some time ago. I can tell you that using this battery pack has provided faultless power on the many ‘Walk abouts” i have had. it is a handy form factor and is reliable. over a recent 48 hour outage it never failed and was only half charged once finished.

    The down side is its expensive, but on reflection its good value knowing how reliable it truly is. I have a few videos on my YouTube Channel where you can see the pack in action – if you have any questions i am happy to help.

    I went through Deal Xtreme. Don’t expect anything pretty but my 9Ah pack has been working well for 3 years now

    Its a bit like this one…..

  • Steve WI2W:

    Check out:

    These packs have built in overvoltage protection, undervoltage protection, and balancing function. Pretty foolproof. They also come with a charger. I think they are reasonably priced and good value for dollar. 2 year warranty.

    Good evening Dan, I have purchased the Tracer battery online and it should be here next week. I went online and there were many reviews all very positive. Thanks for the link and the info.

  • Mike VE3WDM:

    Good evening Alex, great to see you have found something that has out lasted mine by a mile. Not sure what went wrong but a fellow ham and blogger has the same event happen to his as well. I also was informed that this company puts refurbished batteries in the unit….no wonder it only lasts just past the warranty.

  • Mike VE3WDM:

    Top of the evening to you Steve, thanks for the link and it sure is a nice product! I settled on the Tracer product and seems very similar to this one you sent me the link of. It would seem you have to spend close to 100.00 to get the product that will last and do the job.
