Using a rechargeable wireless mouse offers several key 
advantages over one that uses disposable batteries.
Significant Cost Savings Over Time
While a rechargeable mouse may have a slightly higher upfront cost, it saves you money in the long run.
No more purchasing disposable batteries: You eliminate the recurring expense of buying AA or AAA batteries, which adds up considerably over the mouse's lifespan.
Ready when you need it: Unlike a mouse that uses removable rechargeable batteries, a built-in rechargeable battery simplifies power management, saving you the cost and hassle of maintaining separate battery packs and chargers.
Environmental Friendliness
Choosing a rechargeable mouse is a more sustainable option that reduces your carbon footprint.
Reduces waste: It eliminates the need to constantly dispose of single-use alkaline batteries, which are a source of hazardous waste and can be difficult to recycle properly.
Lower environmental impact: By using a single battery for the life of the mouse, you minimize the consumption of resources needed for manufacturing and shipping countless disposable batteries.
Convenience and Less Interruption
The built-in power source offers a smoother and more reliable experience.
Quick and easy charging: You can simply plug the mouse in with a USB cable (often a standard USB-C or Micro-USB) for charging. Many models support "charge and play," allowing you to use it as a wired mouse while it recharges.
No frantic battery hunting: You won't be caught off guard mid-task with a dead mouse and no spare batteries on hand. You just need to keep the charging cable nearby.
Lighter and Better Ergonomics
Mice with built-in rechargeable batteries can be designed to be lighter and more comfortable.
Reduced weight: They are often lighter than mice that require bulky disposable batteries, which can be an advantage for users who prefer a light, fast-moving mouse.
Optimized weight distribution: Manufacturers can strategically place the internal rechargeable battery to ensure better weight balance and a more comfortable, predictable feel during use.
