Recommendations for use your battery powered lamp with its build-in Li-Ion Battery;

What do you need to know about Li-Ion batteries management.

Replaceable Li-Ion Battery in a Reading Book Light

Your LED book reading lamp or music stand light use a Lithium-Ion (Li-ion)  battery, you need to be clear that  Lithium-ion batteries have no “memory effect” as Nickel-Cadmium (NiCd) or Nickel-Metal (NiMH) rechargeable batteries such as those commonly used in digital cameras and MP3 players.

Memory effect.

The memory effect is a phenomenon that reduces the capacity of recharge some kind of batteries, occurs when a person stars charging a battery without discharging it completely before.

Under those circumstances crystals are created inside these battery because a chemical reaction caused by heating or the use of defective chargers.

Our reading lamps and most of other devices now are using Lithium-Ion batteries due they are much more efficient than their predecessors Nickel-Metal (NiMH) or Nickel Cadmium (NiCd).

Then when you buy a device with lithium batteries you should not handle them in the same way you would with other types as you will reduce their duration.
  • Lithium-Ion batteries no need charge before first use, usually come with an initial charge.
  • If the battery is below 20% you must charge it, avoid letting it deplete completely.

Performance

The performance of a Lithium battery is almost the same during its useful life, when you notice a decrease in the duration of the charge is because the battery is about to end its life cycle.

Recharges

Do not allow the battery to fully discharge to start recharging, LI-ION chemistry prefers partial charges and discharges except for batteries on larger devices – such as laptops – equipped with sensor that can suffer a de-calibrate and give inaccurate readings.  In this case is advisable completely exhausting once every 30 cycles, so that return to zero levels.

Disconnecting charger

Most of Lithium-Ion batteries have a circuit which shuts off power once the charging is complete, your battery powered lamp should have an indicator to let you know the charging process is complete.

Of course you must keep in mind that there is always the possibility of the adapter suffering a current peak, an overload or a fault therefore we do not recommend leaving the charger permanently connected.

How long does a Li-Ion battery?

The life time of a Li-Ion Battery depends of several factors; you can expect to last for 1000 charges/discharges or about 3 years, there are some tips to have a better life time:

  • Heat: The Li-Ion batteries are extremely susceptible to high temperatures, so try to use your device in a cool environment will extend its functionality.
  • Storage: If you are not using the device you must store it with a 40% of charge, this is ideal to maintain the battery lifetime.
  • LED bulbs are very low consuming, then your battery powered lamp will runs on battery so much hours before need a new charge and you always have the possibility of use it with the AC adaptor or any USB port connection.

Reusability

It is VERY IMPORTANT that the lamp you buy has replaceable batteries, otherwise you will have to throw away the entire appliance once the battery life cycle is over.

Make sure your new book light is always charged: Know all the tricks!

The most frustrating thing when you need your book light is to find the battery completely discharged, with the following tips you can avoid it:
#1 Know the battery status: press the switch for 3 seconds and the green flashing will indicate the percentage of charge (1,2,3,4 flashes indicate 25,50,75 and 100% respectively)

#2 If the green light flashes periodically while you use the book light, it means that it is about to run out.
#3 Make it clear that you can use the book light while charging.
#4 You can use any USB source (computers, car radio, power banks, other adapters, etc.)
#5 If you use the included adapter, we recommend using the most efficient port that is 1.0A.

#6 Use the lowest light level you feel comfortable with, remember that the charge can last up to 20 hours with a single head on at the lowest level.

Finally, DO NOT THROW IN THE TRASH

You must be careful with the disposal of lithium batteries as they contain chemical elements dangerous to human health and the environment, please do not throw the lamp in the trash with the battery inside, try to remove the battery and dispose of it separately.
