ULTRABATT issues

If anybody else is in the same position as me (waiting months for an ULTRABATT 300CCA to come off "back order") I have an update today from Ultrabatt. They have been taken over by MOTOBATT. The delay has been a result of re-branding. The new range was unveiled at a trade show in Europe earlier this month and are now branded MOTOBATT in the familiar yellow colour. Should be available in retailers from Feb/March 2026.

Oh man. What a drag. Motobatt went tube city about 3 years ago.

Historically I have always used Anti-Gravity Batteries, But I would be interested in trying something new if there is an advantage or quality difference -  Why do yall choose this brand over others?

** I currently use AG401  , AG801s and AG XPS SC-1

I have gone with this for the physical size against power and the internal tech

Is the parent company still the same?  Motobatt batteries have been selling in the USA market for quite some time now.  I've used them in a bunch of my bikes.  One thing to realize, if you let the battery discharge while the bike is in storage, it will damage the battery.  I allowed a fairly new AMG Motobatt battery to discharge, and despite my trying to bring it back up, my meter says "63% health".  I bought a pulse charger, which is supposed to be better than a common battery maintainer, but the battery has not improved.  Once damage done, there is nothing you can do.

Motobatt is the "parent company"  hence the black/red "Ultrabatt" branding disappearing. The key difference from a Motobatt point of view is the addition of Ultrabatts lithium battery range to their offering under the Motobatt brand.

Well this story continues to rear it's ugly head. In May last year I was checking price and availability, found they were on "back order" with an expected delivery June so I ordered one. In June the expected delivery moved to Q3, no issue as I wasn't ready for it. When Sept (the end of Q3) came around I chased again. This was when I was told Ultrabatt had sold out to Motobatt and that the range would be relaunched under the new branding at a November trade show in Europe with stock available from Feb 26. This was OK for me, but Feb cam and went, then March came and went. I followed up again with the supplier in Italy (Ultrabatt didn't have a UK distributor) was told hopefully April ?? Now today I have been told not before June  !!!!!!!!! At this point I nearly "lost my shit" !!!! the bike should be finished in 4 - 6 weeks so after a 4 year build and a battery is looking like being the deal breaker. I don't have the space for anything bigger as the back end was built around the Ultrabatt dimensions, going with anything much bigger will involve completely re-working the back end of the frame and bodywork - words can't describe my frustration right now !!!!!!
