Battery Types

Understanding the different battery types and their performance, for example lithium and alkaline batteries, will help you identify the right choice. Learn which ones last the longest, which ones are best for high-powered devices, and more.

 

Lithium Batteries

Longest lasting batteries with leak resistance and superior performance in extreme temperatures. Ensures your high-drain devices operate at their peak performance and helps you stay powered longer. Holds power in storage the longest compared to other types of batteries. Lighter than standard alkaline batteries.

Ideal for:

  • High-drain digital cameras and flash units that use a lot of power
  • Smart security devices such as wireless cameras, wireless thermostats, wireless doorbells
  • Remote-controlled devices
  • High-use/ high-drain game controllers or gaming systems such as Wii and Xbox
  • Computer accessories such as wireless mouse and wireless keyboard
  • Work-related gadgets such as high-powered LED lighting, laser level or stud finder
 
 

High-Level Alkaline Batteries

Longer lasting batteries that are designed to protect against damaging leaks when left in low-drain devices. Great for mid to high-drain devices. Holds power in storage longer than mid-level and low-level alkaline batteries.

Ideal for:

  • Smart security devices such as wireless cameras, wireless thermostats, wireless doorbells
  • Wireless gaming accessories
  • Remote-controlled devices
  • Alarm clocks
  • Work-related gadgets such as high-powered LED lighting, laser level or stud finder
 
 

Mid-Level Alkaline Batteries

Long-lasting batteries designed for everyday use and best suited to mid-drain devices.

Ideal for:

  • Alarm clocks
  • Torches and flashlights
  • Remote controls
  • Toy cars
  • Disposable cameras
  • Handheld label makers
  • Calculators
  • Voice recorders
  • Smoke alarms
  • Computer accessories such as wireless mouse and wireless keyboard
 
 

Low-Level Alkaline Batteries

Designed for everyday use in low to mid-drain devices.

Ideal for:

  • Radios
  • Calculators
  • Clocks
  • Low to mid-drain toys
 
 

Carbon Zinc

Economical option suitable for everyday use in low drain devices.

Ideal for:

  • Low-drain toys
  • Small devices

Battery Care

Make your batteries last longer with these simple tips.

Battery Tips

  • Store batteries at room temperature
  • Remove batteries from devices when not in use
  • Keep battery contact surfaces clean by rubbing them gently with an eraser or cloth
  • Do not mix old and new batteries, or different types of batteries in a device
  • Do not try to recharge non-rechargeable batteries
 
 
 

Battery Leaks

Alkaline batteries that are depleted or exposed to extremely high temperatures may leak, discharging a fluid which is caustic and can cause respiratory, eye and skin irritation. This liquid eventually forms a 'white fluff' on batteries and corrodes the battery compartment, which could ruin the device.

Any leaking batteries should be immediately removed and disposed of properly.
