Smart Battery chargers
« on: April 05, 2020, 04:32:24 PM »
Driving any of our two cars will be limited to very short grocery trips due to this Coronavirus Emergency.

I am concerned about battery health in my two Mazda cars .     

Have a 2017 Mazda 3, 2.0litre Petrol 120ps Sportnav with a start stop battery. The OEM battery has no usefull info on it. Looking online it seems I must use EFB battery (whatever that means). and I believe it may be a 65Ah battery. I also have a 2016 1.5 SEL MX5 ND with the original OEM 45Ah battery (no start stop).  The Mazda 3 start stop is being defeated ("NOT READY") due to the battery.

Thing is I am looking to buy a good smart battery charger to charge the batteries without disconnecting them from the car.

Not sure what I should be looking for. Can anyone who uses these smart chargers help point me in the right direction?

A few years back I used the excellent Ctek Charger on my Jaguar and it maintained my battery perfectly.

Ordered the-e CTEK MXS 5amp today and hopefully should get it in a week or so. 
Let's hope the batteries aren't flat any time soon since I have never used battery chargers before, smart or otherwise, and don't know they can revive a flat battery.

Neither battery is that old, a few years ago I left my car (with a 6 year old battery at the time) on Southampton docks for a fortnight.

It definitely turned over slower than usual when I came back but she fired first time.

Also weather is good for batteries currently, not cold and not hot.

i use an AA battery  CHARGER which can be used to charge and maintain a car battery ,it tests the condition of the battery before it starts charging.Think I bought it from amazon but its an AA BREAKDOWN branded device.

I had better get onto Ctek and ask for my commission. The charger does have the facility to rebuild heavily discharged batteries I believe, and is the one to use for occasional use vehicles. (Classic cars, summer sports cars etc).

I bought a CTek MXS 5.0 earlier this year, and have connected a permanent connector to the battery so I can just plug the charger in anytime (I bought the kit, that includes extension connector lead, normal and  comfort connector although the LED's flashing I don't like so don't use it)
Mine is a Sport Nav auto, 67 plate.
I mainly got the CTek because I noticed my stop/start wasnt kicking in after I put a dash cam in. Now I pop the battery on charge every now and then it does kick in again:)
I will say I really only use my car at the weekends, as I use a van for work.

Has any one used the NOCO GENIUS5 5-Amp Battery Charger (sold at Halfords), is it any good or better than the Ctek charger?

My Ctek mxs 5.0 arrived yesterday, going to be maintaining the families cars with it. Currently got it hooked up to my sons Audi S3 which has a EFB battery, Ctek advise setting it to normal mode for this kind of battery.
Looks a good piece of kit 👍
