to charge an AGM battery

for stop start battery charging/conditioning

experts required please

 

I've a 180 quid one on my bike c-tec I think and a cheap 15 quid halfords one I had on my Sierra. No difference what so ever in what they do lol the cheap halfords one senses 12 volts and maintains as well

 

it's going to be used on at least 5 different motors, including a ferrari and a porche as well as 2 nearly new mercs with the stopping and the starting stuff plus a beemer so it's got to cover ALL the bases

the one he's been recommended is the c-teck one that's Ł324, is it really worth that much money?

 

Doesn't matter what it go's on a battery is a battery un less it's a fancy new lithium battery

 

it's a stop/start battery, it's not recommended

 

What you mean by stop start battery?

 

The stop start cars have a different battery, which is the agm one with glass and stuff in it so it's not a "normal" battery and you have to disconnect it from the car to charge it
What he's after is a trickle charger to keep it topped up when it's not been used for a month

 

The two I said above are trickle chargers they maintain a battery they sense 12 volts and stop charging. Once it drops to a certain voltage it tops it up again

 

i use a couple of optimate 4 chargers on my bikes and cars
no issues

 

optimate for me too. buy a few extra ends for each car then just unplug each one and swap over. easy.

busters on ebay usually does a good price

 

I used to think the same till my cheap one was side by side with my expensive one doing the exact same job

 

If it is only a month between uses, I wouldn't worry, they will start fine.


Either that, or offer to take them for a run each once a week lol

 

If there is a healthsensor at the negative batterypost, you have to tell the computer
of the car that you put a new battery in it every time you charge the battery, otherwise
the battery won't last long. The battery is kept at an partially charged state so the car can put its "brake-energy" into it (the alternator will charge the battery coasting off throttle, "free energy"). If you do not tell the ECU there is a new battery in it,
it will be treated as a half charged battery and it will not live long.

 

c-tek gets my vote, theyre good and do agm, stop / start battery makes no difference its the agm bit.
agm batteries are used in most stop start cars, vag group, porsche, merc, etc
ring do an automatic charger but ive got one and it doesnt like to go into the float stage. so if i were spending any money id buy c-tek.

 

Any battery charger will charge an amg battery they just don't like being over charged so you need one that maintains

 

I've been using a ring maintainer/charger for a few years now and would buy the same again if I needed another one. I've got a longer lead on mine and have it going through the window and plugged into the cigarette lighter socket.

 

Which ring one have you got mate? There are so many chargers out there he doesn't want to have one per car

 

CTEK MXS 5.0 Ł58.45 on Amazon, covers regular and AGM batteries, I've had mine a while and its a good charger. http://www.amazon.co.uk/gp/aw/d/B00F...M4L&ref=plSrch

 

was looking at that one for my orion.i go out to porsches,astons etc and most of these companies recommend c-tek ones.ebay here I come lol

 

I use a cheap one to for the sierra, one that maintance to and it's just as good as the more expencive onces.

 

Just bought the C-tek MXS 5.0

Looks decent and sounds like it will do the job...also does gel if I ever need it for that
