Thread: Light force spotlight battery

I use a light force spotlight 12v 100w bulb type for shooting deer.
I am happy using this spotlight as it mount on top of my scope and works well. Down side is carrying around a battery....
My battery has finally had its day and wont hold charge so time for a new1.
So was wondering time to upgrade? I am using 12v 18ah sealed type
What else is out there power banks, lithium ion 18650 in 12v form, or a newer typè of sealed battery with better life and hold charge longer...
Any suggestions welcome thanks....
