prepaid meter repair

This remote for prepaid meter was brought to me by a neighbour already opened with complaint it does not show digital numbers when press button are pressed, so as a result she can’t load her token to her meter. So when device was opened she noticed battery had leaked with the battery acid damaging board.

So I did primary checks on board, there seems no component burnt, however battery acid had done damage on board by burning off some tracks connecting to some numbers.

I could hardly see these broken tracks with my naked eyes, but with the use of magnifying lens. So I used copper tracks peeled off from a condemned phone charger board to do the resoldering work, in other to fortify it, I also use 4 mins glue on it and use razor blade to trim it so that the press button can have contact with pads.

Then assembled everything together with a set of new alkaline batteries (Duracell).

NOTE: Substandard cells will always leak.

Pressed buttons number and they all work, call customer for pickup, which she later called on phone she has been able to recharge her prepaid meter with her token joyfully. Pictures below explain repairs better. This is the finished repaired work. Have a nice day all.

    Good job done!
    Batteries like e-caps keep causing problems. And we use many in our homes. The important ones are 9V block batteries used in the smoke alarms on the ceiling in living home, kitchen and bedrooms. And most of those I already replaced by chargable Lithium-ion batteries. And 3 AAA batteries in the Carbon-Monoxide meter in my kitchen next to the cv-combiboiler. Luckily I do not have to keep track of the state of all the batteries because every device will start beeping as soon the battery is almost drained. But I still have to make sure to have a couple of spare batteries charged and ready at home in case that happens to my 5 smoke alarms and one CO meter.

    The baffling thing about some customers is they don't hearken to our advices, howerver I use Duracell alkaline batteries because I have not seen or heard it leak, in fact I use it in my tv remote for 3yrs without removing it and does not leak.Thanks for your comments, have a nice day.

      Imoudu: as long you are using the device there should not be any issues but the problem is they do not use the device for a long time but they keep the batteries in it causing them to leak and destroy the device. Have a blessed day

    I studied your comments critically and I want to ask if you have to modify the charging circuit of those devices using 9V batteries before you can use lithium-ion batteries in them. Most dmm use 9V batteries.Thanks for your comments

      My latest ANENG SZ02 Smart Meter uses 2 AAA's in it .... I didn't see anyone mention a DMM with AAA's in it . I did see Albert's comment on a Co2 meter alarm with AAA's in it , Those meter / alarms are life savers on fishing boats with sleeping quarters ...

    Very well done, Imoudu. Thanks for sharing this different work. Just one doubt: a prepaid meter can be used as electricity meter, water meter, gas meter and parking meter. What is the case here?

    Good Job! Imoudu.O,
    This is called confidence! Before being on this Platform I never touch the equipment if I am not familiar with the operating. I build my confidence because of this platform where experts Encourages us to think & go out of the boundary.
