Battery Charger advice please
 

Over the weekend, my very ancient (it used to belong to my dad!) battery charger finally gave up the ghost, so I need to buy a new one. But there are thousands of them out there! :Confused:

What should I be looking for? Or can anyone recommend a particular make and model?

Thanks - Jim

It's cheap and cheerful from Lidl, but this one got recommended on a Mercedes forum I'm a member of:

They all said it's brilliant. I bought one last week and have been using it for a few days and all is well. Previously, I got the battery warning bleep less than 30 seconds after turning ignition, but now it's much longer.

You need to make sure you get one that will handle your battery!
The CTEK units always get good reviews (see last months Practical Classic mag)

Here's a 2012 review: (They do seem to rate CTEK)

Does anyone know offhand what rating the S8 battery is?

With 3.4A max current it's a bit weak, will take forever to charge A8 sized battery(95-110Ah). It should be OK as maintenance charger that you use regularly just to top up battery but it's going to take very long time to fully charge flat battery, expect 2-3 days for A8 sized battery to charge from 10% to 90%. You should be looking at 10A+ for A8 or even better 20A.

Something like this perhaps: http://www.ebay.co.uk/itm/Ring-RCB32...item19e2a3d673

Jim,

Best battery chargers in the world are manufactured by swedish company called CTEK:

Get this one:

I have installed a CTEK socket with traffic light indicator in my A8 and allows me to quickly connect CTEK charger when led is flashing red.

I can make a picture later for you if you want.

Don't settle for less.

Thanks Guys

I'll go shopping on line later this week

There is no doubt CTEK does good battery charges if a bit expensive but the one linked is only 5A. They do 25A workshop chargers but they are £200+.
I would recommend at least 10A for A8 http://www.ctek.com/gb/en/chargers/MXS%2010

Yes, please post a photo as that sounds a pretty good plan
