Top 9 Best NiMH Batteries of 2021 – [Reviews & Buyer Guide]

Are You Looking For The Best NiMH Batteries?

Have you ever had a “National Geographic” moment when you almost captured the picture of your lifetime when your battery died? Whether it is the high-end cameras or music players, they all drain energy fast necessitating the need for frequent charging or using alternates like the best NiMH batteries in town.

The need for reusable and low costing batteries has increased since the debacle of the rechargeable alkaline batteries. Several renowned battery manufacturers have joined the fray to produce rechargeable batteries especially for gadgets that guzzle energy.

The Ni-MH batteries are the preferred choice of the masses and the manufacturers alike.

Why are NiMH batteries better?

These are the new age batteries which are not plagued by memory effect which just means that unless a battery is fully drained you should not charge it or it will lose its efficacy. This phenomenon is commonly associated with alkaline batteries. The Ni-MH last longer and can be charged whenever you assume they are short of power. They save time and money and are more eco-friendly than the other batteries.

A few notable points

  • The total amount of energy that these batteries store ranges from 1200mAh to 2700 mAH.
  • These batteries lose charge doing nothing, hence to overcome this drawback newer versions have been released called LSD or low self-discharge.
  • The lower capacity batteries can be charged around 1000 times in a slow charge mode while the higher potency ones which are in the range of 2100 to 2400mAH can be charged 600 to 800 times.
  • They are not suitable for smoke alarms which are used only occasionally as these cells lose charge even when not used.
  • Finally, unless you run three to five charge cycles these batteries do not reach their peak output and capacity.

Based on their voltage, capacity, storage time we have compiled a list of nine of the best Ni-MH batteries that you can use in your electronic gadgets like music players, digital cameras, handheld games, PDA, and toys.
