Just wondering if a fault in my Sky as the batteries (genuine Energizer lithium) only seem to last 3 months, and they look as if they are about to go again.

They drop so quickly that it is darn near impossible to throw an alarm to warn that they are about to expire…

I didn’t even get an offline alarm. I did receive a notification and email when it came back online after the battery change out.

That is a normal characteristic for lithium polymer batteries… they deliver to the end and then just die. Sort of like a total cardiac arrest. Most battery types go through a gradual charge decline and provide some warning of their demise. Rechargeable lithium polymer batteries are the same way… …

Just swapped out the SKYs batteries (Ultimates). Lasted pretty much 8mths (power save mode disabled). Remaining voltages: Top group of 4: 1.64v 0.61v 1.11v 1.08v Bottom group of 4: 1.15v 1.60v 0.61v 1.13v I should have kept the vertical pairs together as that’s probably more relevant.

The upcoming solar panel will save you all that trouble. The field tests were awesome. Keep tuned to WF.

Just installed my solar power unit for my sky. I’m so happy. Took maybe five minutes and now I don’t have to worry about sudden lithium death syndrome anymore.

I meant to also give a shout out to the amazing WeatherFlow team. They said they would deliver us a great product and they did. They said they would give us solar power and they did. Top notch work - congrats all around for everything you have done! I’m a big fan.

I received my SPAs for my two SKY units but 5080 was showing below 3V so I decided to let it run until it died. It was a guessing game of, “will it die while I’m gone or or not?” This morning it was at 1.85V but went up before I left. Strangely, it died at 1.93V. I know what I’m doing when I get hom…

For those who are interested, here are the voltages of the Energizer Ultimate Lithium cells taken out of Sky 5080 after the unit shut down. These are in order. Top set: 1.465 1.469 0.3936 1.246 Bottom set: 0.3527 0.3847 1.430 0.586 Totals: 1.8177 1.8537 1.8236 1.83…
