The power necessary to keep your Amiga clock on
the right time, while the Amiga computer is switched off, is provided by a small battery.
After time the clock batteries can leak acid, causing great damage to your Amiga hardware.
These leaks can go unnoticed. There is no noise, no smells, and no outward signs, until
you begin to have failures.
Then it is too late...
It is recommended you replace the clock battery on every Amiga that is more than three
years old.
The batteries are small, barrel-shaped objects with a red or blue plastic covering on
them. The covering is often labeled with the name of the manufacturer (e.g. GP or Varta)
and the battery properties (3.6V, 60mAh). Also, the anode ("plus pole") should
be marked clearly. They are about 1 inch long and almost that in diameter. The
batteries are soldered on the motherboard, with two connectors on one end, and one at the
other, though they look as if they are held by a clamp.
How to find your battery:
Your battery may look like a capacitor on first glance, but it is larger than most
capacitors on the motherboard.
- Amiga 500:located on the A501 (or equivalent Ram Expansion card)
- Amiga 2000: under the drive bridge, where the floppy disk drives are
mounted
- Amiga 3000: near the left edge, in the middle of the main board
- Amiga 3000T: below the power supply, next to the two Kickstart ROM
chips
- Amiga 4000: left side of the main board, near the mouse ports: NOTE:
Newer A4000's use the disk-shaped lithium batteries, and these do not leak.
CHECK YOUR BATTERY: Start worrying if you find corrosive
salts covering the metal casing of the battery:
If you have this sign, you should replace your battery as soon as possible.
Only attempt to replace the battery on your own, if you are skilled with electronics.
Most users should consult a specialist, such as an Amiga Certified Repair Center, any a
reputable computer repair shop, should be able to assist you in replacing the battery.

WARNING:
NiCd rechargeable batteries contain CADMIUM, a toxin.
Thoroughly wash hands after contact with
any leaking battery or contaminated motherboard.
NOTE: Dispose of leaking
batteries responsibly; use a hazardous waste facility. Protect our environment from toxic
materials. |
