    A long shot, but I have just got an old LabCraft TP2mkV leisure bettery charger/box. Now, I have had all leads replaced and it is charging from 240v supply. It has a small round socket & plug that is marked as 12vDC outlet which gives a 12.8ish output.
    On the lid, it states - 3 Way Charge.
    *From 240v Mains.
    *Whilst in trailer trickle through normal wiring system.
    *In boot of car boost charge - No additional equipment required.

    Question - does anyone know how to charge it through 12vDC system.

    There is only a 12vDC outlet? is it charged back through this?
    Any help on htis old battery box much appriciated....

    I have just bought one, but can't get the green charge light to light up. It barely lights the amber one. That is with a battery that I have already charged from a seperate charger.
    Is it broken?
    Any ideas?

    when we had one, we had a lead made up from the towbar wireing inside the car boot to a bugin plug and keep it in the boot for topping it up as we went for days out, moving it back to our trailer tent in the evening.

    It was a great bit of kit, sadly nothing like it around now.

    them was the days:thumb:

    TP2 mains charging

    I’ve just bought a TP2 Mk V from a caravan breaker on eBay (yes, I know!!!). The mains charger doesn’t seem to be working. I installed a brand new 85AH leisure battery which was supplied ready charged. I then ran a small 3A coolbox for about 10 hours without the mains being connected. The battery voltage was 12.5V to start with (green and amber LEDs lit) and fell to 11.7V (only amber LED lit). I then disconnected the coolbox and connected the TP2 to the mains. The mains red LED lights up but not the charging LED. After an hour I checked the terminal voltage and got 11.7V, i.e. just the semi-discharged battery value. Before I send it back can anyone who has some knowledge of this product tell me at what nominal battery voltage the charger should kick in? Does anyone have a manual? I had hoped it would keep the battery topped up after only the slightest voltage drop but that doesn’t seem to be happening.

    Actually I had the original TP with an analogue readout,ie meter. That was nicked when my van was broken into,I then bought another the MkV which had the 'traffic lights' instead of the meter and a different connection system. I have heard it was also known as 'the battery frier'.
    Have you contacted Labcraft for a copy of the manual? Surely they would have it in their record/archives that they could copy or scan and send to you. I think I still have my TP somewhere I may have to have regression therapy to find out where I've put the instructions.

    read that as 'just a FULLY discharged battery value' if it's off load.

    12v is generally accepted as flat at the recommended 50% discharged state

    10.5v is totally dead.
