    I am in need of one, not for woodmaking equipment. Curious about everyone's 'go to' choice for brand?

    My dirtbike's battey has left the building after ~ 5 years. It was a lithium variety in order to save 4.5 lbs over the factory Yuasa lead acid unit. Brand was actually Battery Tender. I bought it because it had a great price on Amz. They are no longer available for purchase. Today looking at two brands to replace it...AntiGravity who specializes in offroady stuff and Motobat which is a brand that I have used before in my street motorcycle. The Motobat is generally considered 'generic' but has incredible spec at same price point as the AntiGravity unit. AG has a fancy phone app thingy...which I'm not really interested in.

    Always have trusted Yuasa in the past for powersports stuff, my bike is a little portly in the scheme of things so I have tried to save weight where possible leading to these Lithium units.

    AC Delco was my favorite Auto battery back when I was young. Stayed with Toyota's True Start (Interstate) batteries while I drove them with Excellent service lives. Dunno who/what the Nissan I have now uses, but it don't look big enough to me coming from Group 27's in my Tacomas (overkill but one of the best places for overkill in a truck...the battery).

    What do you like/use? Opinion based off of service or price points? Bit o both?

    I've had an antigravity in my ktm for maybe 5 years now. I've seen it flat dead and it charged back to life, several times.

    Buddy put an antigravity in his ktm and it was dead in about a year.

    According to Internet pros, Shoria is a good choice. From what I've read, some prefer them over anything else. I've never owned one myself.

    Never heard of them...must be one of those brands that have popped up since my day to day changed from bikes to "almost everything else"
    Like was mentioned, Yuasa was always the big dog...

    Go ahead and correct me if I'm wrong but I can't recall seeing a lithium battery offered from Yuasa. Rocky mountain only offers a lead acid Yuasa for my bike.

    I'm gonna try the Motobatt. $20 cheaper than the others and free shipped.

    First I've seen/heard about them. You'll have to keep us updated when you get one.

    Specs are higher than the others excepting the amp hour (6.0 vs 5.0). The one I put in the motorbike sat for three years (on a tender) and was totally fine when I sold the bike. Guy I sold it to had the bike listed couple months ago and didn't mention a new battery so that's about 5 years or so unless he replaced and did not mention in the ad. An independent shop here sells their AGM's fairly regularly but doesn't stock the lithiums.

    I have an Antigravity in the Duc. Been great. Prior to that, I had the WPS house brand lithium called Featherweight Firepower.

    I ran that in the Ducati for 4 years, then it started cranking slow. Thinking the battery had run its life (this was my first lithium), I replaced it with the AG. Turned out the starter was going bad, so I put the FP in my Simplicity lawn tractor and it’s still working great. I bought that darn battery when I worked at the bike shop (left 2017). So I would not hesitate to recommend them.
    For autos I’ve had great/excellent experiences with Walmart Everstarts (used to be made by Johnson Controls). Typical to get 7-8yrs in my truck.
