hat’s what a new BB-390A rechargeable battery would tell you if it could talk.
The BB-390A needs a “break in” period. Its out-of-the-box performance in
your SINCGARS equipment will only be 6 to 8 hours.
But that figure will improve with each charge cycle until about the third
charge cycle when performance will level off at 12 to 18 hours depending on
use.
Fully charge the BB-390A prior to first use. Use the new BB-390A first at a
TOC, garrison, or other location that can afford an initial low run time. Prior to
the next charge cycle, ensure the new BB-390A is fully drained in your
equipment or via the PP-8448 Discharger, NSN 6130-01-430-3108, and then
recharge. Repeat the charge/discharge cycle one more time.
If you have questions about the “break in” period, call CECOM at DSN 992-
4948 or (732) 532-4948 or e-mail them at:
brockeld@mail1.monmouth.army.mil
