Leaking Batteries.... - Page 2

Bend them a few times and they'll eventually come off.

You do not charge batteries that are not rechargeable.

DUH, even my ass understands that

I meen, why not put in a rechargeable battery in the Amiga?

Erm, sorry for that misunderstanding.. :-)

People want to get rid of them because they have a tendency to leak..

However I personally don't see the problem when using NiMH cells.

It just seems that people want to be rid of the problem once and for all -> coin cells it is.

Do i need to remove the legs holding the battery from the motherboard
so that i am able to use the coin batteries ?

Not really, it's all up to you.

It's neater if you remove the legs and clean the holes, but functionally it doesn't make a difference.

Dr. Dude · 04 January 2005, 20:51

I say clean the holes, why make a mess of it?

Any of the 1N4000 series diodes should work fine 4001-4007. But make sure it gets put in the right way. Stripe end to the motherboard where the positive side of old battery was connected and other end connected to the positive terminal of the battery.

Yes, some A3000s might have problems with the SCSI bus afterwards, though.

Ok....If i remove the battery from my A3000 desktop & A3000 Tower,
what will happen ?

Will they not boot up because they have lost their Scsi settings ?

And if so.....how would i get around this as a temporary measure ?

Would i just save the exact same settings on my workbench disk
and boot from that ?

THX1138 · 08 January 2005, 15:47

Right........i had an old spare 2000 motherboard laying
about,so i used this as a practice run !

I opted to remove the legs holding the battery as well,

Don't think i burnt anything else on the board....hehe

Does this look ok ?

Jope · 09 January 2005, 07:31

It looks fine.

You can use solder sucking wick to clean out the holes. Remember not to heat the pads for too long at a time.

It depends on the machine. Some work just fine.

You need to set them with a boot disk every time you turn the machine on, if your SCSI devices don't work with the defaults.

I haven't used a battmem tool in a long time, so I can't remember whether it can be automated.

But a battery + a clock that keeps time is necessary anyways - I'm so annoyed that my better A4000's clock doesn't keep time (the battery's dead, but I haven't gotten around to replacing it)

What do you mean necessary.......just so that you yourself know what
the time and date is ?

Or will not specific hardware & software not work because of this ?

Jope · 09 January 2005, 11:59

A computer's clock must be set correctly at all times.

No software stops working, but all timestamps are wrong in the files I create and then when I look at my WB's titlebar, I don't see the time.

Muchos annoying. I don't want to dig out my phone every time I want to know what time it is.

One solution is to use an NTP synching program, I guess I might as well install one of those for the time being.. Just haven't gotten around to it. :-)

Edit: NTPSync installed, works nicely.. Miami runs it on startup, so I get the right time every time I boot into WB .. Also found a newer version of AWeb, seems stabler now.

My two Amiga 3000 computers work just fine without the battery. So does my Amiga 2500 and my six Amiga 2000 computers. They all work great without a battery.

I do not recommend this, you could easily damage the solder pads. It is best to de-solder the battery and do not replace it. Your Amiga software does not need to know what time it is. Anyway, the clock will work just fine without the battery, just as long as the computer is on. On bootup you enter the correct time and date. This is only necessary for folks that must have "dated files", like programmers and people that use their Amiga in business.

what, if you set the time it shows on the wb titlebar???? I use os3.9 , never saw time there...

Yes, the clock still works without the battery, just as long as the computer is on.

You may have to use a program that displays the clock in the titlebar. I remember 15 years ago, I used a program called PopCLI to display the Chip Memory, Fast Memory, and Date & Time in the Workbench 1.3 titlebar. I do not know what you would use for Amiga OS 2.x or 3.x because I do not really care about "seeing" the date & time that much.

Because they leak.
If you forget a lithium coin cell inside a computer, it won't leak and fuck up a motherboard. The rechargeable nicad barrels will eventually leak and surely fuck up your mobo in the process....

A Lithium cell lasts eons with this useage, so I recommend everyone making the mod to put one of these instead of the NICd barrels.

This reminds me, my Mac Classic II needs its battery to be removed, if nobody did it already. Never checked the innards.

04 February 2005, 16:52

I can vouch for them destroying motherboards - my A3000 has a hole in the top layer of the mobo from the damage. I'll take a picture, because it's a right mess :-(

Good, would illustrate the point of this thread perfectly
