Question about my "The-Timer"

My dad, being the awesome dad that he is, gave me a feeder timer, The-Timer for my new feeder setup. But I have a question. Does anyone know what the very bottom right symbol is in this picture? I've looked on their website and I know it runs on 2 AA batteries, but when hooked up to a 6v or 12v battery for the motor, it runs off of that...so does anyone know what this is?

I'll also add that when I'm pushing buttons or testing it, the empty area in that symbol fills up to full if that helps any.

It's for your feeder battery, mine have all bars every time I look at it but I do have solar panels too.

So the top battery symbol is for the 2 AA batteries in the timer, and the bottom one is for the feeder battery? I just put a solar panel on so hopefully it'll last me until next weekend lol.

These are the only timers I use or recommend. The bottom indicator is for your 12V or 6V motor battery. As far as batteries go, I have had a rechargeable 12V last 6 months without a solar panel (it was broke)before becoming noticeably weak. I have some that always show a full bar and some that might show one or two bars all the time; however, they always work. Great timers.

That is correct

Check your battery connections might need to tighten them up a little. Some times my will show low until I tighten them up

I've just got alligator clips on the connections of everything in the box. It turned out to just be a low battery. It still slung corn, but I replaced it with a charged battery and that bottom indicator went to full bars. Thanks for the responses yall!
