OT, but always best to also read the owners manual when using ~high end~ batteries as well. For example, another manuf. recommends for maint. charges on their agm, they recommending holding at 15 1/2 volts, which is much higher than even the ~standard 14.7~ for AGM's. Per the previous post, not all batteries are the ~same like~ and it's always best to RTFM.

FWIW, SD, I've had a AGM battery in my care since the 3rd year of ownership. Had had the X for about 13 years now ! After losing out of 2 $$ AGM during that funky electrical issue...I went back to a standard wet cell. Figured even if the X was in the mix for another 18 months or so, I should get at least 5 years out of any decent wet cell.

Sorry to butt in but Can you use a charger to recharge the battery in the car using the under hood connectors? or is it better to take the battery out of the car altogether to charge it?

Under the hood terminals are fine.

So it should be ok.
The OEM Battery lasted 7 years
But we have been through 2 Batteries in the space of 4 years since
If your alternator is working properly and the battery is to spec and holding a charge there should be no reason that you need to charge the battery based on the miles you are driving.

Reply to an old post but here is what ctek had to say when i popped the question of using a ctek(5.0) on an agm battery


HI

We are probably one of the safest chargers on the market and our chargers does not damage batteries.
But you need to always follow the recommendations of the battery manufacturer.
Different batteries have different requirements.
MXS 5.0 has different programs for separate use for each size and type of batteries.

Charging with CAR mode is in 14.4V, with higher rapid peaks in desulphation mode but ONLY if the battery NEEDs it.

reagrds, CTEK

Hello sir/madam, please can you verify if my CTEK will damage an agm battery ? I read the specs and reviews of agm and says charging at over 14.4v can cause damage, and the ctek 5 I see does go 14.4,14.7 and peak at 15.8v in some cases.


Any feedback much appreciated

Nope, they are not as safe as others like the Noco Geniuses

Had 2 Batteries killed by a CTEK charger.

From my testing by keeping 49 batteries charged EVERY DAY the best single battery at a time charger and maintainer is this :

Pulsetech Xtreme Auto Charger



Its not the best fast charger or jumpstarter but it is the best at keeping a battery topped off and healthy. The desulfator function on this unit WORKS. I have brought several batteries back to life with it.

I bought mine here :

One way you tell if a charger is actually desulfating the battery is to look down in one of the cells. If you see stuff floating in the acid after charging with it then its actually doing something. 99% of the chargers that claim to desulfate don't actually do anything. Which is easy to tell by looking at the clear battery acid. Let this puppy loose on a sulfated battery and it will peel chunks of crud of the plates. You can see it working.

I've got like 4 cteks on deck - for the respective battery size. Two 4.3 amp, 7 amp and a 25 amp.

Sorry, google it. Look at the guts of a Ctek and look at the guts of a Noco. Noco has great marketing.....consider how many OEM's choose ctek and stick their logo on them.....
