This question is somewhat ambiguous. 'Battery life' can mean two things... the overall service life of a battery, or the amount of time the battery can power the laptop before requiring a charge.
For an improvement to overall service life:
-----
Create a DOS boot diskette or a DOS boot CD.
Once a month, boot the laptop from that diskette or CD, and let the computer run unplugged at the DOS prompt, until the computer shuts down from low battery charge. Since the hard drive isn't used in this instance, your files and data are safe.
Remove the diskette or CD, plug in the charger, and let it charge fully. You can use the laptop during this time, but be aware that should you lose wall power, your battery won't be able to keep the laptop running until it's again charged up somewhat.
Don't recharge the battery as often. Let it get run down to below 40% before charging it.
On some computers, there is a BIOS setting that will allow you to change how much the battery is charged. Only charging the battery to 80% of a full charge significantly lengthens the battery service life, but shortens the time the laptop can run from the battery before requiring a charge.

For the amount of time a battery can power the laptop before requiring a charge:
-----
Set all components to power down after a short time (hard drive, LED screen, modem, network interface card, USB ports, etc.)
Get more memory if you have insufficient memory to run everything without using virtual memory. Doing so allows the hard drive to spin down more often and for longer periods.
Get a low-draw Solid State Drive. The newer solid state drives often take less than the old platter-style drives.
Turn down the brightness of your LED screen.
Don't use any external USB accessories unless you absolutely need to.
Get a higher-capacity battery.
Some laptops let you use two batteries at once. If yours does, do so.
If you use your laptop outside in the sun very often, consider investing in a solar-charger.
