3.8 BATTERY USE
The following section contains general information and rules, which must in any case be observed, for the correct
use of plug-in batteries.
Lithium-ion batteries can explode, cause fires or generate undesirable thermal effects such as
'Thermal Runaway' if disassembled, short-circuited, damaged or handled improperly. Do not expose to
water, fire or high temperatures.
The battery is comparable to a 'reservoir' from which the product to which it is connected draws the electrical energy
required for its operation.
NOTE:
In this section the term plug-in battery or battery pack may be used synonymously.
The plug-in battery consists of lithium-ion cells based on lithium chemistry, with modules connected in
series/parallel and including a management and control system for the main quantities involved in the perfect
functioning of the battery in its charge and discharge cycles.
Lithium-ion battery technology has become very widespread and is increasingly used in tools, gardening
equipment and many other applications, precisely because it can pack a high energy capacity in a compact
package.
The use of lithium-ion batteries therefore has numerous benefits, but also involves situations that must always be
taken into account, also in light of the fact that lithium-ion battery technology is constantly evolving. Hence, older
batteries may have a lower performance/critical condition:
either as a result of how old/obsolete the battery is;
or if the basic rules concerning battery storage and management are not observed.
The main causes of criticality of lithium batteries, besides obsolescence, are related to the following phenomena:
In light of the pros and cons of lithium-ion batteries, it is good to know that batteries have a limited life cycle from
the moment they leave the factory, however, something can be done to keep them efficient for as long as
possible.
Specifically, the basic rules for better battery efficiency are as follows:
➢ It is advisable to recharge completely for the first time to obtain maximum capacity.
➢ Afterwards, it is best to avoid 'stressing' it with frequent and/or partial recharging
➢ Let it go completely flat, however, every 30 charge/discharge cycles
➢ A lithium-ion battery stays healthy if used often, so it should be kept in 'training'
➢ If you plan not to use it for a while, it is best to disconnect it from the device and store it in a cool place.
Remember that the battery chemistry degrades (oxidises) less when it is about 40% charged; therefore it
should never be left completely discharged
➢ Remember that the main enemy of a lithium-ion battery is heat because it makes it age faster and also
risks creating other problems such as thermal runaway. For these reasons, it is suggested not to leave it
with the device or in direct sunlight or in particularly hot environments, and when the charging cycle is over,
it should be disconnected from the charger
➢ Periodically it is suggested to clean the contacts with a brush with plastic bristles (e.g. polyester or similar)
making sure they are not made of metal material, to maximise the efficiency of the contact over time
➢ Charge in an environment with a temperature between 0°C (32°F) and 45°C (113°F).
NOTE: the estimated battery efficiency after 500 charging cycles is 90%.
