CTek Battery Chargers, any experience with them?


Recommended Posts

Having a regular battery charger (not smart) I was originally just in the market for a trickle one as the regular one was a bit much for my last old battery and kind of fried it. I saw a special for a CTek trickle charger but when I went it store it was 20 dollars more than advertised online which put it closer to the price of their 5 amp version which also has a 0.8 am bike mode that could also serve as a trickle charger. It has a reconditioning feature as well which some say is a gimmick and others not? Reading online reviews these get reasonable praise but also a number of comments claiming their batteries were destroyed by them. Having just done the same to my old battery I can possibly see however how some may attribute blame to a charger not completely at fault.  In my battery's case it sat idle from an accident then once fixed hit with lockdowns , topped up with an old style 5 amp charger that was just too much for it so I don't think its the chargers fault as such but more age and circumstance. But with the trickle function and the ability to add extension leads, sockets and other accessories to it may make a CTek a more usable option. Any users of these out there?

No experience of the Ctek charger, but I do have 6 Lidl chargers, that have the same layout and function's as the Ctek. I use them on my stored cars to keep the batteries topped up, and they work well.

Do you have Lidl supermarkets in Australia ?

It wasn't that expensive from Lidl when I bought it

I have a similar trickle charger with a winter mode button. I might be defeating the objective, but I run it through a plug timer socket that only comes on from midnight to 4am.

I also hooked this up to my lads 1 Series BMW while he was on Ops in Estonia for 6 months and it was faultless.

We were all set to get out first Lidl and Kaufland supermarkets, they bought 20 sites around the country, built a distribution centre,  poached hundreds of workers from other chains then pulled the plug on the whole thing in January. Aldi is quite successful here though.

Just to add, I have to admit that I do not as such use them as a battery charger, mainly I bought them for using as a maintainer across an already charged battery, the one's I have are the XS- 0.5, it has an output of 0.5 Amps and just keeps the battery topped up, and once the battery is at 100% charge (14.4 to 14.6 volts), just pulses the battery as and when it needs to,  to keep battery at its fully charged state, it would charge a flat battery BUT it would take an awful long time if it was say 55AH battery, it may take 4 or 5 days or so, but the thing is, CTEK stuff is good kit, end off.

For info correction - a fully charged battery (that is not connected to a charger) cannot be higher than 13.2v as each cell can be a maximum of 2.2v. The figure quoted is an approx ideal alternator output voltage.

i have 3 of these, fantastic things for maintaining the battery, one has kept my BMW battery good for 7 years, and an escort one for 5 and the other for 3 so far, i also have a LIDL one, thats ok ish, but i dont trust it as when it goes into top up charge mode, it seems to get stuck there
