Another useless thread by yours truly, but I have a new issue
I have one genuine Pentax battery that came with the K-1, and 3 non branded batteries. The non branded batteries are performing badly, literally dying within 30mins from full charge, or at least one or two are (and I'm being unlucky by always using that same crappy one and thinking they are all doing badly when in fact that's just not the case and one in particular is the culprit etc).
In addition to that I am chewing through AA batteries all the time. Yes I have rechargeable's (16 or so), but I still buy brand new packet ones from time to time when I see them on special, but I get in a bit of a mess with keeping track which ones are dead, been used partially and which ones are fresh. (I've done silly little 'drop onto the table' tests to try and get an idea of battery health but yeah I think I want something more advanced than that).
So it's occurred to me that some kind of battery testing device is needed, something to give me an idea of the health of the battery and expected duration/last-ability.
Can anyone recommend something that can be used for the following;
1) A gizmo that can be used for weird batteries such as the D-LI90 K-1 batteries as well as being compatible with more regular battery formats such as AA/AAAs?
2) Something that can make sense of the readings for thicko's such as I. Something that can tell me information such as;
a) If the battery is fully charged or 75% depleted, 50% and so on.
b) Something that allows me to calculate the health of the battery and how long it will last if put in 'x' device that consumes 'y' power? It might be that the battery is fully charged but gone are the days it's going to last like it used to etc.
It might be that nothing can really calculate part 'b)', but it sure would be swell if I could input what the K-1 approximately drains a battery at (it's rated in per shots taken or something? is there somekind of power drain figure given?) and then test certain batteries and just bin the ones that are showing as being pathetic etc. Same for AA's in flashes.
So does anything like this exist, something that's not overly complicated for a thicko like me to understand? I don't mind if the gizmo spits numbers at me that I don't understand as long as I can input said number/figure into some kind of equation given here which would give an indication of health etc.
Battery wise I think I will buy Pentax genuine this time. Last time I literally bought all 3 for the price of 1 new authentic one, but time does seem to wreck these other non branded batteries, they just don't seem to have the same longevity...
Anyone help?
TIA!
