Notes on handling batteries
When replacing batteries, replace all four batteries of each set at the
same time. Do not mix battery types or brands or use old with new
batteries.
When installing batteries, turn off the power of the Speedlight and
never reverse the polarity of the batteries.
If the battery terminals become soiled, remove dirt and smudges before
use, as this may cause contact failure.
Battery power tends to weaken as the temperature drops. It also
gradually decreases when batteries are not used for a long time and
recovers after a short break following intensive use. Be sure to check
battery power and replace the batteries with fresh ones if you notice
any delays in the recycling time.
Do not store batteries in locations subject to high temperatures and high
humidity.
Because flash photography consumes a large amount of battery power,
batteries may not operate fully before reaching the end of their stated
lifespan or number of charges as specified by the battery manufacturer.
