I bought a couple of Aldi AutoXS CPL2054 automatic battery chargers a year or so ago and they have worked really well.

Recently, Aldi had them again so I bought another as did a friend. Whilst they look the same, have the same part no., and the instructional text is identical, they are not the same.
The most obvious difference was the inclusion of illumination for the LCD screen. Inconsequential, I know, but that's what made me look further.
On initial connection, the LCD screen shows the correct battery voltage cf. several of my digital voltmeters.
However, on pressing the Mode switch to start the charge cycle, the metering in the charger reads 0.75 volts low. "So what?", you ask. Well, it means that the charger thinks the battery is low on charge so it commences charge at the 3.8A rate. The problem is that it continues to read low and keeps charging the battery even when the battery is fully charged and then overcharges the battery.
As you can see from my pics below, the battery voltage is 14.86v and the charger reads 14.1 volts and the bars on the right indicating full charge are not yet fully illuminated.

When it reached 15.04 volts, the charger read 14.2 volts and the bars were fully illuminated but the charge indicator still flashed.

Eventually, the system decides the battery is charged and switches to standby. But wait! There's more. The battery terminal voltage now falls slightly so the charger, still reading low, thinks the battery is discharged so it starts charging again.
This testing was done on a near new battery in my Rangie.
Thinking I'd got a faulty unit (see my faulty good thread http://www.aulro.com/afvb/general-chat/36525-my-propensity-buying-faulty-goods-continues.html) I took it back and exchanged it for another.
Well, the replacement does the same and will be returned for a refund. To triple check, I borrowed my friend's unit which was still in the box and, guess what, it's the same. My recommendation to her will be to return hers for a refund.
So, I wouldn't recommend these recent ones to anyone unless I can be convinced I'm totally wrong and, if you have bought one recently (since October), check it.
