Buying guide: What should I consider when buying the best battery & charger for TENS & EMS?

While it is possible to find a large number of batteries of various types that, in theory, are compatible with rechargeable electrostimulators, it is important to emphasize that they are temporary solutions that can do more harm than good to the integrity of the electrostimulator. Therefore, it is necessary to identify the characteristics to which you should be attentive in order to identify a quality battery that meets the specifications of your device.

Among these factors, we can highlight the following:

• Battery type: it is necessary to consider the type of battery used by the device. Electrostimulators can operate with a wide variety of batteries, ranging from lithium batteries to classic AA batteries. It is necessary to consider the quality of the batteries, their recharge mode, if available, and their autonomy.
• Type of use: each type of electrostimulator is designed for a variety of uses, or a particular use, from the treatment of ailments to physical conditioning, and this is a factor that must be taken into account when selecting a battery that can maintain the necessary performance in relation to the use of the device.
• User experience: Selecting the right battery requires a certain level of knowledge and experience with electrostimulators. If you do not have the right experience, you may end up selecting a battery for the wrong reasons, which will do more harm than good to the device.
• Time of use: when selecting an electrostimulator, you should take into consideration whether it will be used for long periods of time, since in the long term it will be necessary to obtain a new battery.
• Warranty: the warranty varies from one brand to another, as well as the places where these devices are obtained. However, in regions such as Europe, the minimum warranty stipulated by law is two years.
• Price: the importance of this factor is linked to the purchasing power of the buyer, but it is rarely a determining element in the quality of the device and its ability to meet the user's needs.
