Product Support Bulletin Subject: Equity LT Battery Life and the AdaptaPAK Battery Pack Date: Page: 9/7/89 1 of 2 PSB No.: S - 0096 Originator: BGB (-7 ;i4 The purpose of this bulletin is to provide the test results of the Product R&D's AdaptaPAK Battery and usage instructions. Like the Equity LT's internal battery, (refer to PSB S- 0055) there are several usage variables that can have a significant effect on the working time. In this test, the Equity LT was configured with the 20MB hard disk drive and the EL (electroluminescent) backlit LCD and set at 10 Mhz. This is the most popular configuration and also the one that consumes the most power. The first test was with heavy access, constantly using the hard disk and floppy disk. The internal battery was previously discharged. The laptop and AdaptaPAK battery were charged for 18 hours. The battery charge lasted a total of 5 hours and 15 minutes before it ceased operation. The second test was with minimum access and the hard drive turned off after powering on. The internal battery was previously discharged. The Equity LT and the AdaptaPAK battery were charged for 18 hours. After turning on the unit, a program that didn't require any keyboard input was executed. The battery charge lasted a total of 8 hours and 15 minutes before it ceased operation. NOTE: The battery lives listed in this document are the results of our tests. Your experience may vary as battery life is affected by configuration and usage. We can also assume that if we were to follow the guidelines (PSB S-0055, P3) to extend the battery charge time, we would get even better results.

The purpose of this bulletin is to provide the test results of the Product R&D’s
AdaptaPAK Battery and usage instructions.
Like the Equity LT’s internal battery,
(refer to PSB S- 0055) there are several usage variables that can have a
significant effect on the working time.
In this test, the Equity LT was configured with the 20MB hard disk drive and the
EL (electroluminescent) backlit LCD and set at 10 Mhz. This is the most popular
configuration and also the one that consumes the most power. The first test was
with heavy access, constantly using the hard disk and floppy disk.
The internal battery was previously discharged.
The laptop and AdaptaPAK
battery were charged for 18 hours.
The battery charge lasted a total of 5 hours
and 15 minutes before it ceased operation.
The second test was with minimum access and the hard drive turned off after
powering on. The internal battery was previously discharged. The Equity LT and
the AdaptaPAK battery were charged for 18 hours. After turning on the unit, a
program that didn’t require any keyboard input was executed. The battery charge
lasted a total of 8 hours and 15 minutes before it ceased operation.
NOTE: The battery lives listed in this document are the results of our tests.
Your experience may vary as battery life is affected by configuration and
usage.
We can also assume that if we were to follow the guidelines (PSB S-0055, P3)
to extend the battery charge time, we would get even better results.
