Trickle charging
 
Having gone to my XT the other day and found the battery to be discharged, I've decided that, especially at this time of year, I should look into trickle charging the battery. I don't ride the bike much during the winter ( because I'm skiing and stuff, nothing to do with being a fair weather biker or anything ;) ) and I understand it's not good for a battery to be heavily discharged and then recharged repeatedly.

However, I understand there may be issues with overcharging the battery etc? Can anyone reccomend a good (cheap!) trickle charger I can leave hooked up to my bike while I'm not using it which will keep my battery in tip top condition?

Thanks,

MAtt :)

The "Battery Tender " is the best ,but it's not very cheap .
Or you could put your battery in a window hooked up to a small solar panel and charge controller .
Or use a low power battery charger hooked up to a timer .
Or ride more often .

Hi Matt, It's not really a cheap option but I bought an Optomiser trickle charger a few years ago ( £30 ish from Hein Gurkin ). It came with a lead to wire direct to the battery ( and another with crocodile clips ) and is easy to plug in, I use it on my XT and GS1150 (not at the same time) and however cold it is the bike fires up enthusiastically at the press of the button - every time. It's pretty robust and has survived a few drops onto concrete floors. I've also bought a connector ( the male bit ) some wire and a cigarette lighter socket from Maplins and made a charger socket that plugs into the Optomiser socket wired to the bike battery ( for charging the mobile phone when I'm out and about ). Hope that's some help.
Cheers Mike

The Tender made it work. Ran cord from Motel room.

I use an Optimate on my bikes; I have fitted a socket to each of them so it's easy to hook up. I also made up a "jump lead" with the same connectors. Most of the lads I ride with have the same socket and it would be easy to hook two bikes together for a boost. Also useful if you rig up an accessory socket/optimate lead you can charge a phone run a GPS, worklight, mini-compressor, etc.

Good bit of kit and well worth 30 odd quid

Thanks for the advice guys. I hadn't thought of using an adapter socket for charging the battery. That would make things a lot more convenient and a socket would be a useful thing to have on the bike.

Will have a look to see what I can get in the UK.

SAE on the other. Very fast and simple.

For what it is worth - Accugard
 
For the past couple of months I have been using an "Accugard" which is a cut down version of the Accumate/Optimate (where do they get these names?).
It is working fine, so far, early days really.
You can find them in the link, buried away within loads of others.

I had one of the cheapo, £10 or so, trickle chargers, which worked OK for a while (some years actually, but it is knackered now): but, it does not do any of that battery monitoring stuff and that makes the Accugard good value IMO.

Thanks for your input everyone. In the end I followed Walkabouts link and got an Accugard charger off ebay which should arrive soon.

Remove battery?
 
I dont know where I got the idea in my mind from, but I thought it was bad to charge a battery (through a socket or direct) with it still installed in the bike because during charging a battery gives off vapours that can corrode surrounding parts of the bike.

Any thoughts, comments or experiance?

I recently purchased a Datatool battery optimiser from Laguna M/C's in Ashford for £39.99 it's great but this morning whilst looking around HALFORD's in Ashford I saw a similar devise which only cost £24.99!

Go to your nearest Halford's and have a look yourself.

I honestly wouldn't leave my bike in the garage without being hooked up to one of these. One UK winter is enough to destroy the battery of any bike laid up until the Summer. Most batteries these days are sealed and you can't overcharge them if you use an OPTIMISER as apposed to a BATTERY CHARGER which may just cook your battery if left on charge for 6 months or more!

Matt,

something that worked on my TT and the XT before, was to drain the carb of fuel prior to starting it - after leaving the bike for a while. Get's all that crap old fuel out, and some fresh fuel in. The bikes always started first prod, as opposed to cough-cough-cough-splutter-cough-weak-cough-start-slowly... Means if you have a low battery, you've a better chance of starting.

If I was more organised I'd probably have drained the carb every time I parked the bike for a while...

cheers,
Doug

Good point about the Carb! - Just close the fuel tank cock and start the engine. Let the carb run dry and the engine will cut out. There done...

And I always cover my bikes in WD40 (not on brakes, disks or tyres). You can't do any harm with WD40 if you stay away from brakes etc... I know there are other more expensive options out there but these are all almost the same as WD40 - maintenance sprays which drive out the wet... I swear by WD40 and you can now get an enormous trade can for only £3.99.

You need a special BMW charger ....and you can use your imagination as to the cost of this little jewel. :helpsmilie:

Matt Cartney 28 Feb 2008 13:43

More great info. guys, thanks. I will definately drain my carb each time I lay the bike up now, sounds like a good tip.

Matt :)
