Battery charging...

[noddyunplugged]

Hi all,
Just a silly question really;
Sadly due to our current 'work-shy' climate, my faithful charriot hasn't seen much use over the past few months and so (naturally) the battery's flat. Instead of actually removing the battery to charge, I've left it in place and just removed the boot floor panel and spare wheel, ran an extension cable from the garage into the boot and set up the charger in the boot. Does anyone think I may cause harm to any of the car's other systems by charging installed as apposed to removing the battery for charging?

P.S.
It does seem to be charging totally fine at the mo and it's an '01 E53 4.4i Sport.

I use a "floating/maintenance" type charger: Battery Tender. I have
used it, via an appliance timer, for weekly charging, for 5 months at
a time, while away. Our '01 3.0 has fired right up with zero ill effects.

Not humping Battery Tender brand, but I would rec'd any brand of
floating/maintaining unit as opposed to a high amp charger/"hot shot"...

Meanwhile, why not use the battery connection bolt points under the
hood, (bonnet)? Easy to attach alligator leads there and one can
close the hood. Easy on/easy off, no moving parts around.

If you need pics of my set up, post and I'll dig out the pics and thread
from history.

I also use my "Tender" to keep that X, my Vette, and 3 motorcycles
charged, in rotation, as none of them get driven on a daily basis...
never an ill effect. My Tender is almost 20 yrs old and runs fine;
the newer models and brands are even better, I suspect.

Hey motordavid, thanks for the reply,

I only went in thru the rear of the X becasue of how i've parked it on our really short driveway to do it, my charger uses croc-clips too.

I've left the charger and everything in the trunk (boot for UK folk), and just have an extension cord trailing over the top of the closed tailgate whilest the upper hatch (glass part) rests close on top of the cord, cord then trails into the garage, garage roller-door shut closed over the cord.

I was only a little concearned about leaving the battery installed whilst charging (which i have done) incase i popped any fuses or upset any systems.

Noddy, never a problem charging/maintaining, with batt installed, that I noticed...
my oe batt went 6 1/2 yrs and I changed it out only to do it on my time, not "its".
The battery well area was nearly pristine, so I detected no problems due to long
"seasonal" charge and, the frequent slow "top up" charges I do.

Just hope you are using a low amp, "trickle/floater" type charger.

Sounds like a good set up.

That's good to know then

Ohhh it's a trickle-charger alright, this thing takes "forever!" lol

I just wanted to double-check as these car's have a lot more kit in them than I'm used to lol

Thanks for all your help!
