The thermoelectric generator SP1848-27145 - a device on the Peltier effect - Seebeck effect to generate electricity and to heat or cool something can be connected to the power source terminals of thermocouple.
List of supported batteries: NiMH / CD AAA / Micro, AA / mignon, Li-ion (26650, 22650, 18650,18490, 18500,17500, 17355, 16340 (RCR123), 14500, 10440)
- a device that uses an external source of energy for charging electric batteries. Typically, the charge carried by an AC voltage of 220 volts.
The structure of the memory includes: a voltage converter (transformer, switching power supply), rectifier, voltage, amperage control device and the charging process, an ammeter or LEDs.
Features chargers depend on the type of battery, rated capacity, the operating voltage.
Chargers are built-in and external.
Chargers used in the industry, are blocks with electronic equipment for simultaneous maintenance of several batteries. This allows you to automatically various long-term operations, such as charge-discharge, charge pulse currents.
Chargers and starters
To extend the life of your battery, you should use a high-quality battery chargers.
- this is a very powerful battery chargers, which are mainly used to start the engine when the battery villages. Their peculiarity is that they can give a higher current and are therefore suitable for launch vehicles. Such devices can operate in constant voltage or constant current.
Depending on the method of charging, battery chargers can be divided into groups:
Charge the battery direct current low value. These chargers are cheap enough, but I have such a flaw can reduce battery capacity by 15-20%
Analog chargers with microprocessor
charges faster than passive, and have the function of determining the end of the charge, but only work on certain types of batteries (Ni-Cd and Ni-Mh).
Digital universal charger with microprocessor
These devices are protected against short circuit; They provide an opportunity to the required value of the charging current.
In addition, the chargers are divided into automatic, semi-automatic and manual (mechanical).
memory for time interval is also klacsifitsiruyut charge: with a small charging time (1-2.5 hours), with a sufficiently large charging time (14-15 hours, sometimes 24 hours), conditioning (about an hour). However, not all batteries can be charged at high speed. For example, lead-acid battery is charging more slowly than nickel-cadmium. Accelerated storage battery charge current of 0.3 C (C - battery capacity). Slow charger charge current in 0.1 C. In these devices, the battery can be left connected to the charger for some time after charging, and it will not lead to any change in its work. And if powerful rechargeable battery will be used powerful enough memory, the battery will always be undercharged and lose some of their capacity.
High-speed (conditioning) memory is charged at a current of 1C and reduce the current after the battery is fully charged. Therefore, these memories are considered particularly promising.
Algorithms charging different types of batteries (lithium-ion, lead-acid, nickel-cadmium, nickel-metal hydride) differ greatly among themselves, therefore, imperative that the type of charging and battery type match.
How it works memory
The important point here is to define the end of the charge. In the cheapest models of chargers charge end time is determined by a preset timer that turns off the current. When reinstalling the previously charged battery charging, the charger will again supply current, and this will lead to a decrease in battery life. In slow memory is not defined at the end time of charge, as an extra hour or two charging virtually no effect on the battery. Sometimes the time of the trip depends on your current absolute value of the voltage. Disadvantages of this method - the voltage may vary depending on the temperature and velocity of the charge. More sophisticated and modern memory incorporate microcontrollers. They monitor the battery voltage, current, temperature, and thus accurately determine the time of current interruption.
Select memory or ROM
The selection is made by a set of basic features, such as inrush current, capacity, power, charge mode. But it is important to note that an important role is played by the versatility of the instrument. If you will need to recharge the batteries of different types, the versatility of memory would be a significant factor. In addition, you may need a buffer battery storage mode, as it improves the performance and increases the lifetime. Thus, when choosing a battery is oriented not only on the basic characteristics but also on functionality.

Prices chargers vary widely, so you can easily find a suitable you.
- is a versatile device for charging lead-acid batteries of different types. Chargers are suitable for charging sealed batteries. Another company manufactures GreenChip classical models for charging car batteries. In the presence there as ordinary chargers and digital, and besides - inverter, allows you to test and restore the battery after the deepest discharge.
Chargers GreenChip have a set of tools that will keep your battery from overcharging. The models provide automatic shutdown of the battery at full charge. Most of the devices have the function of regulating the charge current, as well as the ability to change the voltage. Varied serial number allows you to meet your needs and choose exactly the model that you need
