Having a n00b moment...

Had to replace the battery for my K6 last July, and went with Motobatt;

https://www.motobatt.com/index.php?route=product/product&product_id=93&year=05-09&cc=1000&manufacturer_id=49&category_id=63&model_id=1037

Due to decreased use of the bike, I need to start mainting the battery properly. I have the below charger for my car, but can anyone tell me if it will be fine with the AGM battery?

I should add - the battery is currently low and needs charging. Enough for the electrics, but not enough to crank the engine.

I only use Ctek for all my batteries.

Amazon sell them too.

A charger will boil the battery as it can over charge.

Plus that shit looks Ching Chong. I downloaded the info pdf. What a waste of the Internet that was. Smile

The battery will have maximum charge rate written on it and it will likely be 1amp - so 6 amps is too high.
I would still probably risk it for a short period to get the bike started.
Once your battery has been let go flat it won't last long anyway so you don't have a lot to lose.
It won't explode or anything. Probably.
When your bike alternator is working flat out to top up the flat battery it will output at least 10 amps anyway.

Buy a smart charger - Optimate or CTek are both very good.

Yes, it’s only a cheap charger. But it gifted to me, and works perfectly fine for the car when necessary.

I have a small jump pack to get my bike started. Using this method, how long would I theoretically need to ride for in order for the alternator to charge the battery?

Or watch out for Aldi deals. Their CTEK rip off (re-branded?) is 14 quid and it's done a good job on my jolly sensitive KTM so far.

First off, if you jump started the bike and charged it with the internal charging system, it'd probably be charged with 20A or so, depending on various factors.

(From what I can find - 400w charging system, so around 30A, but the bike will be using some power to run too.)

So 6 amp not nearly as bad as that.

And thus it wouldn't overly bother me.

It should certainly be 'better' for the battery to use this than jump start and charge from the bike it's self.

However, a lower amp charger isn't a bad thing to have.

If you don't need your battery left on charge permanently, a cheap hobby charger like the B6AC gives you loads of options, different battery types and selectable amp output and shows you stats on how much power is put in etc.

Bung it on your charger and charge it noiw. Don't leave it permanently on charge. Once it's charged, it will be absolutely fine for a couple of months if there's no current drain and the battery's OK.

However. Judging by what you say above, if it's been like this for a while, it's scrap. YTZ12S is ~£47 from Tayna (2 year guarantee).

Charge the battery on the bike? Say, for the sake of argument, that it's a 360W alternator. So, 30A max. Let's say 24A 'cos reasons. What's the cranking current? Again, guess. Max CCA for your battery is about 160A, guess when cranking 120A. Time? 6 seconds (urgh!). Safety factor of 3. A couple of minutes would do the job if all else is good.
