Just take note that these are rated in mWh and not mAh. 9000mWh = 6000mAh. It's important to know this so that you can compare apples to apples.

Good catch Norm. I didn't look closely and saw 9000 and that, "9000mah, not bad!"
Interesting idea for batteries though.

It's a marketing word-game gimmick to try to fool consumers who are conditioned to only look at the number. Not the first time this tactic is used, and certainly won't be the last. For D cell batteries, to me, 10,000mAH is the standard since that's what you'll get from Alkalines. If you get that or more, then they are premium cells. If you get a low number, then they are economy cells. Also, while some cells are D size externally, inside could be a smaller cell. On NiMH cells, you'll often find that the AH capacity rating of the cell corresponds to the weight of the unit with heavier cells providing greater capacity.

Agree with superduper. I have yet to be disappointed with my Tenergy 10,000mAh D's. The key to keeping them happy for many recharge cycles is to avoid the two no nos.
1: Never allow the batteries to discharge past 1.0V and certainly Never allow a weaker cell in a group to become reverse polarity depleted.
2: Never overcharge them. They seem to be topped off at 1.47V and then settle to 1.36V after an hour or two
Do this and they will last you 500 charges before you even start to see a decline in performance. Love these batteries. With a smart charger you can't go wrong.

I enjoy using rechargeable batteries in my boxes. I rarely use AC power even when I'm in the house. While a set of D's are ripping it up in a box another set is hot off the charger ready for consumption. It's like a bakery around here. A rotisserie of D size specials 
Are you noticing any boxes seem particularly “weaker†on the 1.2v cells vs 1.5v or no difference? Also do you have a later model lasonic? Wonder how they do with the lower voltage.
I need some of those wrappers. Do they sell ultra power ones? I need to upgrade my cells to as much power as possible.

Right off the charger I don't notice much at all in performance change however, once the batteries go from 1.3s to lower 1.2s the bass deteriorates slightly. It usually takes around 6 to 8 hours before this occurs in my heavy hitters.Superduper said:
