Powerex Precharged D

these are the batteries that you can depend on, i purchased several powerex batteries and i used them to power my eton field radio and they are very reliable, doesn't drain fast and if I may suggest use the powerex mh c808m charger designed to charge d cells, for quite sometime these d rechargeable batteries were out of stock finally amazon replenish their stocks and iwas able to order several packs of these batteries, low self discharge rate is added feature since the radio that I am using them with consumes a lot of batteries, somewhat pricey but I believe they are worth the investment in the long run, a much better alternative for alkaline batteries which are quite expensive and sometimes, they leak which will damage your equipment. these batteries are quite hard to find and different stores do sell them but with added costs, sometimes you will be charged with the shipping, almost one third of the cost of batteries. amazon ships it for free most of the time. I do hope that amzon will re-stock the mh c808m and the powerex 100 minute cool chargers, grateful to powerex and amazon for leveling the playing field!

I've owned several sets of Powerex batteries and they have always performed well. This review is specifically for the Powerex D cell 10 Ah variety. I bought these in 2016 and as of 2023, they are still working well. Capacity as reported from my Opus charger is still around 9970 mAh, which I think is great. Although I have them 8 years, I probably only charge them about 4 times a year, so they haven't been cycled too many times. When I bought these, they cost about 60% of what they do now. Given that in the devices I use these in that I would have gone through about 4 sets of regular D cells per year, the breakeven for me came after 2 years, so despite their high cost, they have still saved me quite a bit of money. I was kind of shocked to see the price of them now, so that would be the only negative, but I guess you get what you pay for. They are true D cells with the corresponding higher capacity, not C cells that have been put in a D cell case. If you don't need the kind of capacity these provide, you can save some money buy buying the lower capacity cells, but if you do need the higher capacity, these work very well.

These hold a charge for a reasonable length of time but they don't last long. I have had two fail out of six that have been in use for a little over a year. For what they cost, this is NOT acceptable! Not sure I will buy any more. I might just use alkalines instead since D size rechargeables are nearly impossible to find.

These batteries are my favorite especially in the D cell side and they really do last for long periods of time even if not used and last longer than any batteries I have when being used. You won't find a better battery anywhere especially for high drain devices.

We tested a few dozen D cells and discharged/charged them three times to maximize output. In the end about 5% were greater than 9,500 mAh. Most were 9,200 - 9,400 mAh. Some were lower than that. The label states 10,000 mAh in big font and 9,000 mAh in teeny tiny font as the minimum. The old design non-LSD Powerex were north of 10,400 mAh but of course would not hold the charge as well in storage.

What is going on with Amazon Quality Control???? Original Order had 1 Battery out of 2 DEAD (cannot charge)...I just received a replacement and the plastic casing/package is cracked / compromised....Looks like it was opened and returned.... Followup: The replacement order also has 1 defective battery and it looks like the batteries were used. The second battery was okay

So far, so good. Initial break-in on the MaHa charger shows mid 9400's on them. Minimum rating is 9000 so they split the difference between minimum and full-rated.

I bought these in March, and I am seeing reduced rates after about 6 months. One battery is failing- it doesn't hold even 50% charge any longer. One of the batteries holds about 75% capacity. The other two batteries have held up decently, and seem to hover around 90-95% capacity. The quality control or the longevity seems to be the issue.

I don't like the price, but I have have many Powerex batteries, and all, including these are well-made and last exceptionally well.

Excelentes duran mas que energizer. Las utilizo para el calentador de paso.

Muy buen producto para el chispazo del calentador..hoy lo coloqué y después les aviso cuanto tardo la recarga

Good high capacity batteries

Just as described. Thank you so much.
