Charging battery whilst still connected

[Morcs]

Is it possible to do?

Ive had battery problems of late, and even with a new battery I dont think it will be the end of it considering the TLs charging system is so crap.

Can I just hook up my charger to the terminals whilst everything it still connected?

If not can I do it with just disconnecting the -ve?

Just getting the bolts back in is a pain in the arse and I cannot be arsed.

Of course you can I do it all the time.

Just don't try to start the bike or dick around with any electrics while the charger is hooked up as it will very likely blow the fuse on the charger - if it is so equiped.

Cool, thats all I needed to know.

Just hook it up first then turn it on at the wall - less chance of sparks

Just use a little 4 amp charger and you will be fine. Don't use a massive 25A industrial one and put it on "boost" coz the regulator will get real hot.

It will possibly charge quicker if you disconnect it, as the regulator will start to shunt some of the chargers' current afer a while. Also be aware that automatic chargers might never show their "battery full" green light, because the bikes' regulator will clamp the voltage down (like it's supposed to do.)

If the battery fuse is handy I would just pull the fuse out. Shrug, its just the easy way.

I've just bought a Battery Doctor (not the name on the box but its the same thing) to trickle charge my battery. It plugs into the power outlet accessory port and I'm told you can maintain a number of batteries at the same time with additional connectors.

I had to jump start the Duke once and that was a right pain, especially when I was running late. Take off lower fairing, mumblefarg.... mumblefarg......

So, I've purchased a couple of short ignition leads - probably only needed one for positive terminal but didn't want to shag around sparking off the frame for the earth. I'll clamp the leads to the battery and position them for easy access in future so no more mucking around with fairing screws etc.

... and pay attention to what you're doing.
I had some handy-dandy quick-connect leads on my bike for plugging the battery charger into, but somehow managed to connect the wrong lead to it in an incestuous loop. Less than 2 seconds later it was smoking, and of course I couldn't unplug it, as it was too hot to handle.

In the unlikely case that you battery is an old-style, non-sealed type then don't charge it without un-buttoning cowls/seat/fairing. Otherwise you could end up with a hydrogen fuelled BBQ between your legs when you next start her up

Getting a new one today, so no worries there.

Mines one of those $30 jobbies from repco. its about the size of the battery itself. should be ok eh?

Yep. Otherwise known as a trickle charger, you'll be fine.

I asked this question a while ago in relation to the Guzzi and it's potential for a power surge to stuff the computer, general consensus seemed to be to play it safe and disconnect. The manual advises against jump starting and crash starting for the same reasons, otherwise I have charged all my vehicles over the years with everything still hooked up without probs.

I have a permanent flush mounted DC socket on the side of my bike (mounted through a hole I drilled in the plastic) which is hard wired through a 10A fuse to the battery under the tank. I cut alligator clips off my 3500mA Projecta charge & maintain unit I use and put a 2-way connector plug on them and a socket on the charger lead so I could still use the alligator clips when need be for other batteries, and made up a new lead with the matching 2-way connector as well, and a DC plug on the other end. This has the added bonus that not only can I charge through the DC socket, I can plug any 12V device in there too if I want (not that I've bothered yet).

Excellent idea.... I may copy it on of these days......Thanks

It is quite handy. I even made up a lead with the 2.1mm plug on it and banana plugs on the other end that plug into my multimeter, so I can measure battery condition by checking battery voltage while cranking without removing anything - that gives a good indication as to the battery serviceability. I'll make up a cigarette lighter socket to plug into it too before the 'Kiwi this year. It might come in useful for a light or cellphone charger...
