Rechargeable Ni-Mh Batteries - 20 + AA Cell Size (2900mAh) - 19.95 at 7 Day shop

2900mAh is good to have powering your item for longer than something like 1800mAh :thumbs:

:thinking: It may help if you mention that the price is for 20 batteries ..... I thought iut was for 4 & that it wasn't such a good deal :$ :lol:
 
After use for awhile I find them (also 2900mAh Ni-Mh) need a top-up after two weeks
 
I'd rather buy the newer Eneloop technology batteries that come precharged and will hold their charge for up to a year.

You could get 20 of them from 7DayShop (their own brand) for around £20 as well.

I've found that eneloop batteries are FAR better. In a lot of cases the quoted mAh just doesn't seem to be realised in reality. Eneloop on the other hand does seem to give you exactly what's on the tin.

Yeah but these are 2900mAh not 2100 - 2900 is better :thumbs:

I think that depends how recently they've been topped up as Eneloop or 7 day shop's equivalent "Good to Go" batteries are designed to hold their charge a lot longer so potentially the 2900mAh could have lost more charge than the 2100mAh!
 
Well to be honest I have no used the 7 day shop branded 2900's.

I use the Uniross 2700 Encore and they are superb so I was just assuming the 7 day shop 2900 would be good also
 
John, I'll back you up here. The 2900 7dayshop batteries are great for the money. I have eneloops as well and they're a different beast. I keep those for back-up as I know the 2900's will run down like a normal rechargeable, but the advantage of about a second quicker recycle at full power is worth it.

Try charging both sets of batteries up, and then putting them in a drawer for a few weeks and then use them and see which are actually better ;)

That is not a fair test, Dave. The eneloops are designed to hold a charge like an alkaline, whereas the 2900's are a standard nimh rechargeable, but with more power. They are both great at what they do.

Except that's the way most people use batteries, charge up and put them in a flash, camera, torch, whatever. Two or three weekends later decide to take some photos or need a torch to find something in the dark. Click and the old tech batteries barely work while the eneloop style will still have 95% charge.

Not many folks will remember to charge 2 or 3 sets of AA rechargeables the night before a weekend away.

And I haven't even brought up the problem of overcharging the batteries every month "just in case" you might need them.
 
But these batteries are not aimed at that market. They're aimed at the strobist who goes through batteries a lot and really needs or wants that extra second recycle.
 
Having got those 2900mAh from 7 day shop I can say without hesitation how long they last.
Using them in a Nikon D300 grip which hold 8 at a time and checking the pictures after each one in the rear screen I was only getting about 100 shots before those particular batteries ran out of power. Not very good in my opinion so I have ordered the EN-EL4a Nikon battery with the cap and charger instead (still to come)

I thought everyone was on about using them in a flash gun, ah well back to the start, and go over the thread again :lol:
 
I agree. They're not at all designed for a grip!
