RE: Re: [RCSE] JR 8103 lithium battery failure question
I went through this with my 10x. I did manage to replace it myself, but I am in the business, and a professional risk taker. A joke :-} I would not recommend replacing the battery yourself, in fact Horizon is very reluctant to sell one to you for your own installation. Why? Several reasons. It is hard soldered in, at least on the 10X. If you do not remove it carefully you will damage the radio permanently. If you do not use a grounded professional grade soldering iron you run the same risk of zapping your radio innards. Moreover, the replacement cell is a generic type which you have to modify by using a dremel tool to relieve some metal on the solder tabs. Is it worth the risk to do it yourself? I do usually send radios back for a bi yearly check up, If your radio is more than three years old, take my advice and have it gone over and have the Lithium cell replaced by the very competent Horizon tech dept. and protect your warranty.

Re: Re: [RCSE] JR 8103 lithium battery failure question
I believe if you leave the TX battery connected you can change the lithium without fear of losing any settings. I think I saw that in the manual. Dennis - Original Message - From: "Robert (Bob) P.

Re: [RCSE] JR 8103 lithium battery failure question
Why worry about what will happen ? Just send it back to Horizion Hobbies and get a new Lith battery installed--and ask them to check the xmtr over while they have it. I sent my 388 back last year and got excellent service, reasonable prices and about a 2-3 week turnaround. No need to push your luck.

Re: [RCSE] JR 8103 lithium battery failure question
Karl, I would be guessing, but even though a low battery condition exists on your Lithium battery it should be at least a week possibly a month before it was low enough to start to lose memory.

Has anyone experienced what really happens and how long after the flashing L appears does the lithium battery last until it completely dies? Just wondering in case this happens at an out of town contest if it would still be safe to fly. Thanks for any info, Karl Miller RCSE-List facilities provided by Model Airplane News.
