I was let down by the battery last weekend. While it is probably my fault, it meant I had to swap out the TeleMetrum for a non-trackable flight computer. This led to an hour of whacking bushes so to speak in farmers fields. This is what I got the TeleMetrum to prevent. So I have some questions about the best way to care for and handle the battery. (I’m using the 900 MaH LiPO)
When I last used the device, I’d returned from the field exhausted. I just set the rocket aside with the battery still connected to the TeleMetrum. I knew this would drain the battery, but I thought it would be no worse than that. When I did take it out to charge, I found that I’d actually left it on, so it had been transmitting until it died. Oops. So I put it on to charge overnight before bringing it to the field. I’d never actually checked it until I got to the field. The battery hadn’t charged at all. It was dead. I put it on a car charger for a little while, but I was getting nothing. So I had to swap it out for another, less capable, computer. When I removed the battery from the foam I had wrapped it in, I also noticed that it had swollen, and was no longer the flat battery I had put in. So my questions are: 1. Is it normal for a battery to fail after being fully and completely discharged, or do I have a bad battery? 2. Is the swelling of the battery normal? If not, what would cause this? 3. What are some good ‘Best Practices’ for the care and handling of the battery?
