The brand leader for baked beans is Heinz.

In the "Which?" blind taste test of baked beans, Morrisons own Value Baked Beans (29p) and Heinz Baked Beans (64p) achieved equal scores (70%).

Seems like a credible analogy here.

Very credible

I buy value*** not a label.


*** "value" in this case meaning performance or taste per unit shekel.

Just got some batteries for my K3 from UK Battery (China!) and they must have strapped them to a snail to deliver them too but they did arrive and though they were stated as 2000 MAH, on arrival I notice they are rated at 2800 MAH! Time will tell!
You never know the original has been out a good while and tech moves on...

DSTE batteries and charger arrived today well packed. If attention to detail is anything to go by then they should be OK. Both batteries arrived in individual plastic bags in individual boxes inside two cardboard boxes. The charger is described as a travel charger and comes with an adaptor for UK use. I won't be using this as it is a fast charger.
Both batteries display as fully charged and K5 operates OK with them. How good they are will become apparent in time, "I'm just going outside, I may be some time....."

2800 Mega Amp Hour - they will certainly last. Might have trouble putting one in the camera though.

2800 mAh maybe ...

To be even more pedantic and with a point:

Hours are represented by an 'h'.

'H' is magnetic inductance whose unit is the Henry, which is in turn 1 Weber (a unit of magnetic flux) per Amp (Wb/A).

Therefore MA.H is the product of 1 million Amps and 1 Henry.

so multiplying out you get:


10^6 A x Wb/A which makes 10^6 Wb or a mega-Weber.

I'll settle for that!

Or even a Mega-Weber! I did think of the same but thought that would be too technical for a lot of users. It does however demonstrate what the effect of using an incorrectly capitalised "prefix" can be.

And I thought you were just a barbecue! or maybe a pico-gram-weber !
