During the middle of the night on Saturday/Sunday, I got a low battery voltage warning on the KX3. That struck me as odd, as I had recently charged up my 12V 10 Ah battery. I was expecting it to last the entirety of Field Day. But in the heat of battle you really don't think twice about it, so I took it off line and hastily replaced with a recently purchased 12v 5 Ah battery that I had gotten about two weeks ago. THAT battery lasted the second half of Field Day without a whimper.
When I got home from work on Monday, I put the 10 Ah battery on my charger and was getting a battery failure indication. It was reading at a level of 10V and 0% capacity and would not accept a charge, I was wondering how can this be? It was purchased new and I haven't put it through nearly enough cycles to have exhausted it. I figured it must be a battery charger fault, so I hooked up the 5 Ah battery to the charger to see what it said. The 5 Ah (which was in use for roughly the same amount of time, if not more) was down to only 11.8 Volts and had 89% capacity left in it! And the charger's fan started running as soon as I hooked it up.
No charger fault - I got a bad 12V 10 Ah battery. Dang!
I don't remember where I purchased it, whether it was from eBay or Amazon, but it doesn't matter. Its not like you can return a battery some 11 months after you've bought it online. I had purchased it after the 2023 Skeeter Hunt when my last deep cycle battery gave up the ghost. I don't want to be scrambling for electrons during the Hunt this year, so I went on eBay and found an economically (cheaply) priced 12V 10 Ah Deep Cycle Gel Cell battery.
I know, you guys are probably thinking, why didn't he go lithium? Price mainly, but also because I don't feel like purchasing a dedicated lithium battery charger. I once ruined a small lithium battery by not using the correct charger on it and I don't want to relive that escapade. I learned that lesson well. However, should this battery not last longer than a cycle or two, I guess I'll bite the bullet. Maybe spending a little more right now would be the right thing to do in the long run, but I guess I'm too frugal to have reached that point yet.
It should be at my house in about a week - long before it's needed for the Skeeter Hunt on August 18th - which, by the way, we've had 93 sign ups so far and the 1st Day of Summer was only 6 days ago!
And looky see what came in the mail yesterday!
