Power Boost: Get More Battery Life!

Consider Upgrading for Maximum Efficiency and Longer Run Time

Looking to get the most out of your device? Upgrading to a battery with a higher milliamp hour (mAh) rating can be a simple way to extend your device's run time and performance without additional effort.

Why Opt for a Higher mAh Battery?

A higher mAh battery holds more charge, which translates to extended usage between charges. For example, if your current battery is 2200mAh, switching to a 3000mAh option offers approximately 36% more usage time. This means less frequent charging and more productivity.

Benefits of a Higher mAh Battery:

  • Longer Usage: Enjoy more time between charges, ideal for high-demand applications.
  • Less Charging: Focus more on what you need to do, with fewer interruptions.
  • Enhanced Efficiency: Perfect for power-hungry devices like cordless tools, smart home gadgets, or other electronics that benefit from extra power.

Is a Higher mAh Battery Safe for My Device?

Yes, it's completely safe. The voltage stays the same, so your device will operate as usual, just for longer periods. A higher mAh battery is a reliable and effective way to maximise your device’s performance.

How to Check Availability:

Higher mAh batteries may be available for various models. To check if an upgrade is possible, simply search for your device’s brand and model. Some options are available across a range of models, so make sure to explore.

Battery Care

Operating Instructions

  • All new batteries should be fully charged. After completing 2-3 charge and discharge cycles, the battery will achieve optimum capacity.
  • After the battery is fully charged, unplug it from the power source to prevent overcharging. Note: Most modern charging stations and devices automatically stop charging when the battery is fully charged, so manual disconnection may not be necessary.
  • Disconnect the charging unit from the power source when not in use.
  • Store batteries at moderate temperatures. If batteries will not be used for an extended period, remove them from the device and keep them in normal indoor room conditions.
  • Isolate batteries from metallic objects such as coins, clips, or pens when carrying an additional battery.
  • Ensure the positive (+) and negative (-) ends of the battery are facing the correct direction.
  • Avoid fully charging and discharging the battery if possible: While most modern devices manage charging effectively, it’s still advisable to avoid extreme charging cycles to prolong battery life.

Warnings

  • Do not apply batteries to reverse polarity or other devices.
  • Do not continue to charge batteries beyond the specified time.
  • Do not crush, drop, mutilate, or penetrate with foreign objects.
  • Do not use or charge batteries if they appear to be leaking, discoloured, rusty, deformed, emitting an odour, or otherwise seem abnormal.
  • Do not spill water on the battery or get it wet.
  • Do not dispose of batteries in a fire or trash incinerator, or leave batteries in hot places or under direct sunlight, such as inside a vehicle.
  • Do not attempt to disassemble, puncture, or modify the battery.
