Battery leak

[Youngted]

A pal of mine has left old batteries too long in a T2 machine. Now it will not work due to the damage.How expensive would a repair be? I suppose the mother board would have to be replaced.

Brian,try Dave @Pentechnic he is the UK repair centre.

Not really sure why the name in the last was deleted but could be seen as petty especially when it was no active link and trying to help someone who has trouble with a detector.

Send it to him by PM. Non-sponsoring commercial links usually meet the same fate. Findmall policy.

In a T2, the batteries are away from the electronics. If he did not leave it turned on, the "brains" should be fine. If it was left sitting in the "on" state, the corrosion can travel up the wires. Leakage from storage would be confined to just the battery compartment. They share space with the speaker, which may or may not have escaped damage. Chances are a factory repair would be to just replace the battery/speaker section with a new one. It probably wouldn't be covered by warranty. If the corrosion is not too bad, sometimes it can cleaned away and the weak terminals renewed or rebuilt with a little ingenuity.

ALWAYS RECHARGING 9 VOLT BATTERIES AND FOUND THE MALLORYS WILL POP SOMETIMES
HAVE NOT HAD 1 EVEREADY ALKALINE POP YET
BOTTOM LINE ALKALINES SEEM TO STAY LONGER IN STORAGE THAN CARBON
LITHIUM BETTER IF RICH

I would avoid using carbon-zincs in most any detector. Detectors from the 70's are designed to use them, but not many newer models will work right or be safe having them inside. Yes they can be leak-prone, especially in models that use soft-touch type power switches, as they often have a tiny bit of battery drain even when turned off and that's what will make a carbon-zinc battery leak if left in once they are used up. If you check them for good voltage and make sure they are fresh, you are good, but don't forget and leave them in a detector for months of closet storage.

Don't judge a battery by how much advertising they have. At least one of the biggest names with a copper top has a pretty bad rep for leakage.
