Motobatt Failures? - dickturpin - 20-12-15

Anyone else had any failures on their Motobatt battery? I'm suspecting mine has failed . Under load the bike won't start. I  just get a buzzing noise. It's on charge at the moment on a different charger to see what voltage I can get in it.
Bought in April 13 from Busters so will have done about 10k miles.

I've got a motobatt in mine and it has lasted two winters so far with no issue's. It sounds like yours just needs a good charge and it will work again. The buzzing is your solenoid trying to turn the engine over.


Re: Motobatt Failures? - taylor - 20-12-15

mine didn't last one winter, :rolleyes


Re: Motobatt Failures? - dazza - 20-12-15

My local bike shop's workbench has always got a selection of failed Motobatts on it.
Yuasa all the way for me.


Re: Motobatt Failures? - dickturpin - 20-12-15

Just tried the old battery that was in the bike prior to the Motobatt.... I had kept it on the bench for testing 12v kit..charged it up and bike started....guess that confirms the demise of the Motobatt Sad


Re: Motobatt Failures? - nickodemon - 20-12-15

Did your motobatt not take a charge? What exact model is it, as fleabay advertises two part no's for the fazer and it's the MBT14B4   that should be fitted NOT the 12 model.


Re: Motobatt Failures? - dickturpin - 20-12-15

Yes its the 14b4 model....it shows 12.8 v straight off the charger (I realise I should give it half an hour) but just doesn't have any guts under load of starting.


Re: Motobatt Failures? - slimwilly - 20-12-15

Check all connections,,under loads they could be holding back your ooommmph, lol


Re: Motobatt Failures? - nickodemon - 20-12-15

Try leaving it on charge for as long as you can, as it might just not have a good enough charge in it. once charged check the reading and recheck an hour or two later.  I had a yuasa battery in mine a couple of years ago and it lasted one winter, so i won't buy them again. (they used to be the best batteries, but i think there standards have dropped over the years Sad )I have an alarm on my bike, which kills the battery. My motobatt has worked perfectly for the last couple of years. Do you have an optimate?


Re: Motobatt Failures? - dickturpin - 20-12-15

No optimate but it has a trickle setting I can leave it on for 24 hours and see what happens when I put it back on the bike. Seems there is a lot of luck in battery life with differing views on different makes.

I deal with batteries at work on a daily basis in the film industry.
Old or new, batteries and chargers can go wrong, doesn't matter on make whatsoever, shit happens basically.
I have a feeling mine's a Motobatt which i've had a few years now and i was off work last year for 3 months without using the bike and it started straight away when i needed it to.
You need to phone them up and ask what the warranty is on batteries, as in my opinion they are a very good brand.
I'll ask the electronics fella at work if he knows general warranty periods as well in a few hours and let you know.


What amp charger are you using on it too, be very careful if you mention charging it off the bike because if you've used a charger that's got too much ampage they could use that as leverage to point the finger at you for possibly damaging it. 


Re: Motobatt Failures? - dickturpin - 21-12-15

When I checked last night I had 12.88 v in the Motobatt and 12.94 in the old battery.
Appreciate the comments about warranty but my contract is with suppliers not Motobatt direct...unless they offered any goodwill.
Battery always charged on 'bike' setting on charger.


Re: Motobatt Failures? - dickturpin - 21-12-15

So the motobatt had dropped to 11.4v overnight but the old battery had only dropped to 12.4 v


Re: Motobatt Failures? - darrsi - 21-12-15

Unfortunately the fella at work who mainly deals with our batteries is off work now, sorry fella.


Just read elsewhere though that MotoBatt warranty their batteries for 2 years!


Re: Motobatt Failures? - Grahamm - 21-12-15

Take it to a friendly garage and get them to put a Load Tester on it.

I had a brand new one that was duff from the word go. Took a charge, seemed to be ok, but had repeated issues with the bike being difficult to start, it turned out that one of the cells was duff, so the Volts were fine, but not enough Amps.


Re: Motobatt Failures? - darrsi - 23-12-15

I did get to talk to the person who deals with our batteries at work and he said that a standard warranty would be at least one year, but for more expensive ones they could give you two years, which is what I read about MotoBatt items.
Without me even mentioning it though, he did also say that it would be a factor on what you used to charge it with, which is what I said before about using a charger that is too extreme for a smaller battery.
Even though they will charge it quicker, and then cut off when done, it will decrease the battery life over time much quicker than normal.
I've said on here before, if a bike is used regularly then it is more than enough to keep a battery in good condition, even more so if a bike is garaged overnight.
Main problems occur with bike batteries when they are not used regularly, or are constantly left outside in very low temperatures during winter, which is totally understandable.
Other culprits that can add to problems tend to be alarms, or even other items that are wired straight to the battery and don't get turned off when finished with.



Re: Motobatt Failures? - dickturpin - 23-12-15

Thank you Darrsi
The bike is garaged but gets infrequent use at this time of year. No alarm, just a couple of power sockets left wired to the battery but no appliances in those sockets.
I have contacted Motobatt following the start of this thread...interested to see their response.
Will keep the thread updated.


Merry Christmas everyone!

Whats all the fuss about these Motobatt's anyway? I seem to read just as many bad reports than good :\


Re: Motobatt Failures? - dickturpin - 28-12-15

So this was the response....
[color=rgb(33, 33, 33)]Motobatt has a 24 month warranty, if your battery has last you three seasons that is good going, and it's now outside the warranty period.[/color][color=rgb(33, 33, 33)][/size][/color]
