Lithium-Ion Battery Charging Best Practices
Bigblue Dive Lights uses the safest Lithium-ion batteries on the market today. They are specifically
designed with protection circuits to the exact specifications of each light for maximum safety and
output. Keep reading to learn more about Lithium-ion battery charging best practices you can apply to
extend the life of your dive light!
Many of our customers choose aftermarket batteries, and the truth is, it’s a bit of a gamble. There are
hundreds of somewhat comparable Lithium-ion batteries on the market but unfortunately, they are not
all created equal.
The biggest problem, (aside from the obvious safety issues), is that they may be slightly shorter in
length, causing the contacts to be misaligned. This will cause flickering, or in some cases, the light
will not function at all.
Bigblue Dive Lights – Battery Care & Best Practices:
• Fully charge before first use.
• Plug in charger before inserting the battery.
• Observe correct polarity. Red light = Charging. Green light = Fully charged. Remove battery.
• Avoid letting batteries drain completely
• Do not turn light on if fully discharged.
• Use only Bigblue Chargers
• Don’t leave the battery plugged in once fully charged and don’t leave the battery charging
unattended, especially overnight.
• Keep batteries in a cool, dry place, away from extreme heat or cold which can reduce lifespan.
• Prevent dropping, puncturing or crushing batteries
• Remove battery if stored for a longer time.
Charge after each use. For long term storage store at min. 40% charge.
Monthly charging recommended even if unused.
Safety Tips:
• Never leave batteries unattended while charging.
