Internal battery failure - Spypoint LINKSDARK Link-S-Dark Solar 12 MP Infared 100 Ft Camo None SD/SDHC Card

I have owned a dozen or so cellular trail cameras from various manufacturers. Overall, I like Spypoint the best. I thought this camera was the final solution. No batteries. Put it in the field in good sunlight, turn it on, and never have to go back. That was how it worked for 9 months. I had it in the field full time since I got it. Recently, pictures became intermittent. Then, they stopped all together. The battery showed to be dead. When I pulled it from the filed, it was completely dead. The on / off switch didn't do anything. When I plugged in the charger, it powered on, showed charging, but the battery % showed 100%. When I unplugged the charger, it was dead and wouldn't power on. I plugged it back in for a full day. Still dead.
So, I loved it while it was working. I'll be sending it back to Spypoint for warranty repair / replacement.
