Whether for flashlights, toys, or other devices, these batteries have been reliable and powerful.

I have never had this much charge left in any battery after 6 months…but the again….
Price
I love that they can be recharged up to 1000 times, making them super cost-effective in the long run.
Amazon won't let me relay anything about my size c amazon basics nimh rechargeable batteries that were purchased on 6-19-20 for $12.
I can hardly wait to see the size d prices, if and when they get stock on them.
That is quit a price increase in little more than 2 years.

These were delivered on 3/1/23…these all had a date code of 09/2022…i started my normal discharge/charge cycle on my iq338xl charger.

The fact that they come pre-charged is a huge bonus, and i was able to use them right out of the package.
Competitiveness
With all the batteries i have so far purchased, i've noticed little difference between these and other brands.
