So when I sorted my click no crank with mods and a brand new motobatt gel battery in July 2017 I thought Job Done
wrong
6 months later motobatt reads 9v , won't charge or hold charge.
I'm about to send it back to Busters, Swansea for replacement
(I feel an argument coming)
£64 wasted plus an £18 motobatt charger
I think an old fashioned lead acid replacement being bought.
bike charges ok
battery is fooked in under 6 months

Looking on various forums motobatt gel battery don't look as good as the sales pitch makes out
they don't like extremely cold sub zero weather
( been minus 7 in my garage recently )
Battery killed

Been there with these 'super duper' moto batt things. The yellow ones yep?  My DR650 was bugger to start come winter time and despite having bought one from wemoto they insisted I didn't charge it properly.  I've got 3 seperate chargers and I expect the bike to charge it too. But , no...not interested. They aren't what they're cracked up to be.  I just buy yuasa now and stop the shopping around.

My biggest problem is that the lead acid come dry charged. You try buying acid in mid wales. Probably a 70 mile trip to Aberystwyth

Most batteries come with the acid packed separate, to be added when commissioning, I think it`s more to do with shipping regulations. I`ve never heard of having to supply your own acid

Hmmm. My latest bike purchase has a new Motobatt fitted, so I’m hoping it’s going to be ok. I usually buy the lead acid type, delivered with a separately sealed acid supply, which simply “ plugs in” to the battery, dispensing the acid safely and accurately.

Had mine for three years, occasionally use a trickle charger. No probs even with my low mileage or maybe that’s the answer??


Perhaps I should keep an eye on it!

I've heard two different opinions on Motobatt, one extreme case was one which lasted all of a few days, others have lasted years.
 
My favourite is Westco batteries from Tayna. They are a battery specialist (in Wales).
 
By the way, many batteries come dry with a filling kit. The important point is to leave it for at least 6 hours after filling before attempting to do anything more. Use it immediately and you will reduce the life.

as above -the initial charge can make or break a battery, plug & play is a recipe for a short life.

my motobatt required charging last night , was new just last year.
 
I will change the alternator belt and see if it improves but this thread is making me feel there's not much hope.
 
thanks Guys

Before you fiddle about changing the belt, read my post about the alternator wiring.
 
Run the engine and check the voltage on the battery. It's very possible you have a bad connection somewhere in the charging wiring from the alternator to the battery.

Whenever I need a replacement battery I get a Motobatt. Of all the electrical things that have failed on my last three bikes, using them all through the winter, it’s never been the Motobatt battery. Stored outside, no trickle charger.

As I said, some have lasted years, some only days.
But it will also depend on which battery on which bike.
All the older models don't have the parasitic drain of the ECU and dash, so the battery gets a far better life. Add to that all batteries fitted to the older models are far larger capacity.

My lawnmower battery bought from Tayna and as recommended by Mike H works great, 40 quid and has lasted three years so far, useful little handle too: https://www.tayna.co.uk/895-Enduroline-Lawnmower-Battery-P8379.html

I've got Motobatt on all my bikes and have had no problems at all, in fact I can only praise them based on my experience.

My 916 had a Yuasa lead acid battery before and it would run down enough to not start if left more than a couple of weeks, initially replaced it with the same again but it wasn't long before it did the same. 

Monster has a Motobatt although, to be fair I've never had a different battery on that as my experience with the 916 made me get a Motobatt from the off. But it has a very high compression and even with the added CCA/larger cables it still turns over slowly but reliably - they can be troublesome bikes to start.  

When I bought the Guzzi it had a new Banner lead-acid battery (the seller fitted it a couple of days before I bought the bike as the old one was dead) and it would often struggle to crank it over fast enough to start, especially after sitting a week or two.

Both replaced with Motobatt and both now start first time, every time and don't need topping up when not in use.

All my bikes have voltmeters and a comparison of volts indicated during cranking shows favourably to the Motobatt - Guzzi would often show 8v or less on the lead-acid whilst cranking, where as it's more like 10 -11v on the Motobatt. 

The Guzzi needs more power to crank than either Ducati (I think the starter gear design is the culprit?) but will start even at a slowish crank where as a 916 can be cranking OK but won't start if the voltage is slightly low as the ignition/injection/fuel pump are all dependant on a good voltage - would imagine modern Guzzis have similar problems?

Also the equivalent Motobatt has more CCA than the lead-acids they replace, which obviously helps.

The only downside is that they are heavier (Motobatt on the Guzzi is around 10kg!) but I'd rather carry a couple more KG than try to bump start a heavy, high compression V-twin.

They also make a black version of the model used in Guzzis/HDs because they're essentially on show and the yellow looks a bit garish...
