Problems last Update G10 and G10t in Relay Digital Wireless Posted April 19, 2020 11 hours ago, phil_m said: Hmmm... Well, last time I got my transmitter down to the point it was flashing red, which was like last weekend, it stayed that way for over 20 minutes. I didn't actually let it die, so I just recharged it at that point. It really does seem to me that people are seeing very disparate behavior from their batteries. All I know is the firmware is probably clamping charging currents, or just squeezing the math, to fool the battery charging logics, and that’s to prevent a thermal runaway, without have to recall the hardware. Whatever they did, it ruined the charge cycle lifespan by a good 40/50%, depending how many cycles the battery has/had.. Also, let’s jump on that old statement from DI; “Here's the scoop: According to the battery vendor, the G10 transmitter specs at or better than 80% of its capacity after 300 full charging cycles. 300 full charging cycles equates to 2,400 total hours of playing, so if your gig is only one hour long, that means 2,400 gigs and 2,400 charges. What happens after 2,400 total hours of playing? Probably nothing, other than the battery might max out at 6-1/2 hours (80%) instead of 8. This is on par with Apple laptop batteries and better than many smartphones, both of which'll see way more usage than a wireless guitar transmitter.“ None of my G10 has been used for 300 full cycles, not even close. One of them had probably 50 cycles, the oldest probably 200, and in fact they were all lasting a good 6.5/7 hours before to blink red. The third unit, was a gift, that has been barely played, so it has few cycles total. As DI mentioned, battery life wasnt a factor originally (and in fact nobody ever complained about old batteries being weak), as it is not for any average Li-ion battery, which btw should last in the range of 500/1200 cycles, depending on specs and currents.
