12V - 55 AH / 5 HR
Taken from the 1996 manual. The specs for the 1993 should be the same.
Used cars such as the Honda Prelude may be purchased from Auto Park Burlington or Toronto Honda. They have good quality cars that usually get traded or come off lease.

I assume by the question that you have a bad ECU, and want to replace it with a used one from the junkyard. I, myself, managed to take an ECU out of a 1995 Honda Prelude S and it runs without a problem in my 1991 Accord. The 1990 to 1993 Accords share the same motor as the 1995 Honda Prelude S, so the computers are interchangeable. Also, you might want to check what engine you have. If you have the F22A6, then the computers are NOT interchangeable.
You need to contact a Honda dealer who will sort this out for you.
There are many good sources in order to find a used Honda Prelude for a fair price. You can go to Auto Trader which is a very reliable company or a used car dealership in your area.
Removing the motor on your own is a daunting task, and it is not an easy way to answer this as it didn't specify what year and trim level Prelude in the question. My suggestion if you decide to do this is to pick up a Honda Prelude service manual for whichever particular year Prelude you own. This comprehensive manual is often used by authorized Honda service departments and auto enthusiasts that want to do their own repairs. replacements, and maintenance.
The best way to look for a used Honda prelude is through a dealership near you that also sells and buys used cars. It's also a good idea to check out Craigslist or Auto Trader to see if anyone near you is selling one.

The standard engine for the 1992 Honda Prelude is the H22. The H16 will also fit. However, it was used in many of the older models.
You can buy a service manual from Helms, Inc. (see related link). The manuals are used by certified Honda mechanics.
The answer is no. The fuel-injected engine from your 1987 Accord is a direct-fit into a 1985-1987 Prelude Si, but will not fit into a 1988 or newer Prelude due to a completely different engine and transmission being used. The wiring harnesses and ECU will also be very different.
You can use Prestone.
