ctek charger

Hi my ctek charger has come today. It has an option for charging to 14.4v and 14.7v . I think I have seen 14.7 v mentioned here somewhere for charging. Is that correct.

Thanks for that. Which manual will tell me what charge rate to set then, a range rover manual is it.

i find it useful to read the manual of the product you've bought.

here, allow me to google it for you to save your fingers.

"14.7/5A AGM charging"

To save you the stress of googling that term

"AGM, short for "absorbed glass mat", batteries feature fiberglass mesh between the battery plates which serves to contain the electrolyte. Both designs offer advantages and disadvantages compared to conventional batteries, as well as each other.
"

The ctek instructions say, 14.4v for wet,ca/co,mf,gel and some agm batteries.
14.7v for most agm batteries like optima and odyssey.
hence my confusion.

Yes i googled that too..i just want to know wether to set it to 14.4 or 14.7 . that nonsense means nothing to me. Thanks for your reluctant help all the same

haha, you sounded like you couldn't be arsed looking

if yours is a normal lead acid just use 14.4V

if it's an unknown AGM then again i'd stick with 14.4

14.7 is useful when it's cold as the temp causes differences to charge rates. Also some batteries like optima will tell you exactly what's what. ie Support - Battery Care - Charging | OPTIMABATTERIES

afaik though, if you constantly 14.7 charge unknown batteries (ie chinese with no specs) then it can shorten the lifetime.

but tbh, i doubt it matters much at all, especially as it's a smart charger.

Nice one I shall set it to 14.4 then, I would have gone for the higher option . Using the search here 14.7 is mentioned . I think the ctek instructions assume that one is already an expert on batteries which I am not as my post shows.
I came back expecting another flaming from you lol

How much did that set you back? Aldi's £13.99 must be very smart, push the mode button till the car symbol shows and that's it

if you tried to find out and got stuck, then that's good with me

but you come across loads of lazy people who don't even bother to try and help themselves. they'd rather ask on a forum than a quick google and err i become a bit bitchy

58 pounds on Ebay,its the version 5.0 I bought a ring smartcharge 1st but it was faulty out of the box so I ordered one with a good reputation . Cars been going flat in 2 days of late so plan to keep it on charge constantly.Or until I get around to trying to find the reason. It doesn't get used much maybe once every week or 2.

Well the Aldi one is perfect, I use mine when I'm away for 3/4 weeks at a time (Roll on 2 weeks tomorrow) It won't charge a flat battery but will maintain a charged one.

buy a multimeter and you can do a few checks.. or take it to halfrauds and they'll check the battery for free.

In nearly 30 years of motoring I have never needed a battery charger or charged one up.Other than batteries for my powertools,they all vary in type but you just plug it them in and come back in a bit. No thinking req. Not being lazy just trying to make sure as it seems nothing on these cars is as straightforward as I wish and as I said I would have gone for the 14,7v as I read that was the alternator output.

All checks done, battery A ok, r/f fine now but I've had flat batteries in the past and it's cost me a shed full of money. For the cost of a charger I've never had a problem for the past couple of years.

Thought I would be clever and use the hardwire and quick connect kit , loosened battery live bolt now have a dash warning about resetting windows. They go up and down tho .lol

When you disconnect the battery you have to reset the windows, the procedure is in the manual...

Get in, turn on ignition, close doors, open the first window, keep your finger on the button for 2 seconds at the bottom of the travel, then raise the window (it will beep at you and tell you it is not set), keep your finger on the button for a couple of seconds at the top (it will beep again and then tell you the window is set)....repeat for the other windows and the sun roof!

The Aldi one is a Ctek one that's why - just the base model.
