How To Change Your 3.6V Clock Mac Battery

How to change our your Mac battery

How to change out your Apple Macintosh pram battery

Changing out a battery is not difficult on most Mac systems. Simply pry off the retainer and pull the battery out.
Reverse the procedure with the new battery making sure the + is positioned correctly.

Restart your system and reset the date and time and other control panel settings as needed. Note 4.5V Batteries are small square and black. They are stuck down with velcro. Simply pull up the old battery and unhook the cable. Reverse the procedure. There is only one way the cable plugs back in.

How To Change Your Coin Cell Clock Battery

remove your computers coin style clock battery

install a clock or button style clock battery

After powering down and unplugging your system, open your computer and locate the battery on the motherboard. It may be easier to set the unit
on it's side.Slide the battery out from the holder. A small screwdriver may help but use caution, the pro's use a small plastic non conductive tool.
A plastic knife or ice cream stick would be a decent and safer substitute for a removal tool.

IMPORTANT: Slide the new battery in, making sure the + POSITIVE symbol shows up. While extremely rare, it is possible for an improperly installed battery to explode.

Button up and restart your computer. Using preferences, reset the clock and check your other settings.

Batteries contain chemicals that may be harmful to the environment. You should dispose of used batteries at one of the recycling centers.

Read about proper battery disposal

Once you've replaced the battery, you will want to reset several settings. If you're on a network, you'll want to open the Chooser and enable AppleTalk. Note some Macs may not support all these control panels (preferences in OSX). These are the control panels you'll need to use:

  1. Startup Disk. Always reset your startup disk. Your system may not boot well or give you the flashing question mark if it gets confused.
  2. Date & Time. First, choose your time zone, then set the date and time.
  3. Memory - Mac OS 8.5 and later will usually set this automatically. Set your cache to a Meg if you have plenty and 1 meg over on virtual.
  4. Network or AppleTalk. If you're on a network that isn't LocalTalk, you will need to reset your network connection on any Mac with a LocalTalk port.
  5. Mouse and Keyboard. You'll need to reset the mouse tracking and double-click speeds, as well as setting the keyboard delay and repeat.
  6. Energy Saver or Auto On/Off. Energy saving settings, power-up time, etc. are stored in PRAM and need to be reset.
  7. Monitors and Sound or Monitors & Sound. You need to reset speaker volume and monitor bit-depth -- and possibly resolution.

Beware of Substandard Batteries

I was looking at some of the pram batteries sold by our competition. No one sells batteries for less than we do, and no one sells fresher batteries than we do. I saw a couple who advertised lower prices but by the time you paid shipping and handling you end up paying substantially more. What really bothers me though is some of these low priced specials were lower milliamp batteries. Before buying any 3.6 V Lithium Battery that fit in most of the Macs make sure the batteries you are getting are 1200mah. Remember we import these batteries direct and they are not made before we order. While lithium batteries have a long shelf life, most batteries in the states these days are several years old. Ours are no more than 4 months from the date they were created.

When pricing laptop batteries you should always compare the milliamp hour rating (shown as mAH). Sometimes a bargain is not a bargain if it doesn't last long in your laptop. More is always better.

Mac clock battery in its native habitat

Has your system recently lost its mind? If your clock is not keeping time you need to immediately replace your clock battery. Failure to do so can cause drive errors and loss of data. Lithium Batteries last 3-5 years, and the Alkalines last as little as a year up to 2 years. These are exact replacements for Tadiran, Saft, Maxell, Rayovac etc. and meet or exceed OEM specifications.
