Pros & Cons

Update Pros and Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

I use a tens unit which came with weak nmh aa batteries. On my headlamp, they work at full brightness around over two hours. Considering high end nimh batteries are around 900 mah at mostly 1.

They hold about 650mah but need the special charger. They also have a built-in micro-usb charging port so you don't need a special charger just for charging lithium rechargeable batteries.

I feel i am due a refund on this purchase from the company that sold them through amazon! Still deciding whether to return or replace.

Quality

No complaints, they have a great performance and are charged easily

Easy to recharge and didn't notice any physical defects.

These li-ion cells work verywell and the charge indicator shows full after many uses.

They last about 10 hours on a full charge.

Price

They have saved me so much money buying throwaway batteries that are bad for the environment when they go in the trash.

Even at a $40 investment to start, this will save you money in batteries.

I know you’re not supposed to mix voltages w batteries but it’s a cheap light and the batteries aren’t too expensive so i’ll ta... Read More

Competitiveness

I see no need to go back to the disposable ones from costco

I have some of another brand that suffered the same fate.

Lithium aa batteries are far better than nimh or nicad batteries.
