Yet another DUD battery ,, !!!
What is wrong with modern AGM motorcycle batteries , I gave up on Motobatts as they were so unreliable 3 in one year 2 were changed under warranty in Thailand , replaced with a Yuasa ?????, Then 2 Yuasas in less than 2 Years in UK ,, Now a Unibatt in UK only 18 months has died its showing 12.8v but 2 cells are down when a load goes on ,, I am trying a French/belgian Made Fullbat this time ,,,
In years past Yuasas and Motobatts used to last me 5 years at least ,,, None of the bike have charging problems ,and I use optimates as well. Other people are telling me that they are having similar issues with very few bike batteries lasting more than 2 years even on brand new bikes .....

FWIW I use jmt / jmp batteries on all my bikes. My 1100evo has had one in for four-ish years and starts no bother.
A local parts shop I use doesn’t like jmp, said he’s had a few issues. But certainly that’s not my experience. |

My Motobatt is now over 11 years old and still never been on a charger.
I might have to relent and give it a little trickle, as it's gone down to 11.7 volts after being off the bike for nearly a year. I think you must be buying those fake batteries Jerry? Always buy from a reputable source. For what it's worth I think optimates kill batteries.

Same as mr gazza here. I don’t trust optimates, never put my batteries on trickle charge.
The evo battery has never seen a conventional charger, my streety RS has once and that’s about it. |

Well, to put in my twopenneth, I use Yuasa batteries bought from a reputable source and they seem to last 5, 6 or more years. I always have and probably always will leave all my bikes permanently on Optimates or C-Teck battery tenders to zero ill effects since the late 90's. Currently I own 3 999's from '03 to '05 which must have similar systems to older Monsters. They always start off the button when I run them 4 times a year or so. Standard cables, standard batteries. I'm happy this way as it seems my bikes are too!

Last battery was Yuasa in the M750 bought from wemoto ,,, lasted 17 months 2 dead cells when tested under load ,, New battery in today is Fulbat bought direct from Fulbat main agent UK
The 3 Motobatts were from main importer 2 died under warranty the other lasted 2 years I always buy from reputable sources ,, and avoid Chinky copies .
