  AGM and Gel Batteries – The Heart of Emergency Power

  Maintenance-free batteries made with AGM (Absorbent Glass Mat) and Gel technology are the foundation of any emergency power system. They are specially designed for buffer operation, where they are fully charged most of the time, waiting for a mains power failure to immediately take over powering the connected devices.

  Key features of our batteries:

  • Maintenance-Free (VRLA): The sealed design eliminates the need to add water and allows for operation in any position.
  • Long Lifespan: Designed for many years of buffer operation (typically 5-10 years depending on the model).
  • Low Self-Discharge Rate: Can be stored for a long time without losing charge.
  • High Performance: Capable of delivering high currents in a short time.

  Main applications:

  • Buffer power supplies for alarm systems
  • Emergency power for CCTV monitoring
  • Computer UPS systems
  • Building automation systems
  • Cash registers and payment terminals

  Choose a reliable 12V battery (e.g., the popular 7Ah, 12Ah, 18Ah) from Actii.pl and be sure that your system will work even when the power goes out.

  AA/AAA Batteries and Rechargeables – Reliable Power Source

  Batteries and rechargeables in popular sizes AA (R6) and AAA (R03) are the primary power source for countless everyday devices. From remotes, through toys, flashlights, computer mice, to cameras and game controllers – efficient cells are essential for their operation.

  Disposable Batteries vs Rechargeable Batteries

  At Actii.pl, we offer both types of cells to match your needs:

  Disposable Batteries (Alkaline, Lithium)

  • Alkaline Batteries (AA/AAA): The most popular choice for low to medium-drain devices like remotes, clocks, or mice. They offer an excellent price-to-capacity ratio and a long shelf life (up to 10 years).
  • Lithium Batteries (AA/AAA): Significantly more powerful than alkaline, ideal for high-drain devices (e.g., cameras, flashes) and for work in extreme temperatures (high and low).

  Rechargeable Batteries (Ni-MH)

  • AA/AAA Rechargeables (Ni-MH): An ecological and economical solution. Although the initial cost (batteries + charger) is higher, they can be charged hundreds or even thousands of times, dramatically reducing operating costs.
  • "Ready to Use" (LSD) Technology: Modern rechargeables (e.g., Eneloop, Varta Ready2Use) are pre-charged and have a very low self-discharge rate. They retain up to 80% of their energy after a year of non-use, combining the advantages of batteries and rechargeables.

  Other Battery Types

  In addition to standard "sticks", our offer also includes:

  • 9V Batteries (6F22): Used in multimeters and smoke detectors, among others.
  • C (R14) and D (R20) Batteries: For high-power flashlights and older radios.
  • Button/Coin Cells (CR2032, CR2025, LR44): For watches, calculators, bathroom scales, and memory backup on motherboards.

  Choose reliable power from Actii.pl. We offer alkaline and lithium batteries and high-capacity AA/AAA rechargeable batteries from leading brands.

• Chargers Rectifiers

  Battery Chargers and Rectifiers

  This category includes specialized chargers and rectifiers designed for charging and maintaining various types of batteries. Unlike simple power supplies, these devices have advanced circuits that control the charging process, which is crucial for the safety and lifespan of the cells.

  At Actii.pl, you will find primarily:

  • Chargers for gel / AGM batteries: Specialized chargers for maintenance-free batteries (VRLA), commonly used in uninterruptible power supplies (UPS), backup power systems, alarms, as well as in electric toys and vehicles. They charge the battery in a controlled manner, preventing overcharging and "gassing," which is critical for gel and AGM cells.
  • Car rectifiers: Used for charging lead-acid batteries in cars, motorcycles, and boats. Modern microprocessor-controlled rectifiers automatically diagnose the battery's condition, select the appropriate charging current, and have desulfation and maintenance functions.
  • Chargers for AA/AAA rechargeables: Designed for charging popular Ni-MH "sticks" (see Batteries and Rechargeables category).

  Why can't a simple power supply replace a charger?

  Charging a battery (especially gel or AGM) requires precise voltage and current control. The charging process is usually multi-stage (e.g., constant current charging, then constant voltage).

  • Risk of overcharging: Using a standard power supply (e.g., 12V) to charge a 12V battery will lead to overcharging once it reaches full voltage. In the case of VRLA (gel, AGM) batteries, this leads to irreversible damage.
  • Safety: Rectifiers and chargers have short-circuit, reverse polarity, and overheating protection.

  Take care of your batteries' lifespan. Choose a professional charger or rectifier from Actii.pl, tailored to your cell technology (gel, AGM, lead-acid).
