Are these the eneloop "stay charged" type, I'd never by normal NIMH again now, they go flat just too quickly.
#2
No these are standard NiMh. The duracell terminology for the hybrid type is StayCharged. Agree that the hybrids are great, but I'll be using these AAAs in a bike light which will mean frequent battery changes so they won't be sat around in a drawer for very long...

Agreed these would work in a bike light situation, though 12 might be a bit over the top as I would not charge them and leave them sitting around. If you have a use for 12 then good deal, but must admit my money has been spent on updating all my standard NIMH batteries to Hybrids.

People see "Duracell" and think it's special, it's all the power of advertising no more, if you want standard type, I suppose the price is OK, but who wants standard rechargeables now?

I don't buy standard NiMH batteries any more, the Low Self Discharge type cost little more, and suit almost all use better - this type have a habit of remaining discharged in a drawer while you buy disposables at a high cost because you need them straight away!

These are normally around £5 per pack, so this is a great buy!
#6
Went in at lunch time. There were other brands more expensive than £4.99 for a pack of 4. Energisers were ~£10 for just 4 batteries.

So getting 12 Duracell NiMH for £10 is awesome - serious heat!
They are rated at 1000mAH so they have to be alright.

Okay so we know that NiMH drop charge if not used in a while, but until the stay charged type come down in price, I would advise buying 3 packs if you have a lot of AAA devices. My DECT phones at home use AAA, TV remote and the like... Cant go wrong IMHO.

Just checking on those FAMOUS Eneloop batteries that people like to recommend - Yes they hold charge for longer... but only just...

http://en.wikipedia.org/wiki/Low_self-discharge_NiMH_battery

Standard NiMH batteries like the ones in this thread, lose half of their charge in one year
Eneloop one dont lose as much - just 15-30% over a year... now I dont know about you, but I am not bothered about them losing charge over a year... in a few weeks/months maybe.

What is all the fuss about Eneloop for then if they are only 20-35% better? (over a year)

A year?
Most rechargeables are uselessly flat in a couple of months unless the LSD type! The voltage drop alone makes them a problem in lots of gear.

Clearly you haven't tried them, like chalk and cheese!

Depends which sources you believe, Eneloops are supposed to maintain 85% charge after 1 year, rule of thumb for normal NiMh is 1% self discharge per day, so that's a big difference. That matches reasonably well with my personal experiences of NiMh versus hybrid.

I would be using these batteries in my cordless phone. Is it best to put the phone back on its dock (and charging station) only when the batteries are running low (and need recharging), or can the phone be put back anytime its not in use?

In theory NiMh like to run full-empty but TBH we've been using AAA powered DECT phones at home for 5 years, phones live in charging cradles, and the phones are dying before the batteries so I'm not convinced there's much difference in practise.

Just buy them you can't go wrong. They'll last ages and when your phone needs charging just place in back on the phone base for charging. Job done :)

I bought the batteries - they were a great buy as per comment #5. Just thought I'd ask the above as well!
