Battery Life
« on: December 25, 2016, 10:15:16 PM »
Random question,  I know battery life diminishes with age each time it is charge.  is there a way of telling how good a battery is, with out the obvious of using it from fully charged and taking a note of how many pics it does.  Reason being i currently have three batteries for my camera,  One of which is relatively new and the other two quite a bit older (should have marked it somehow shouldnt have i)  with getting the new A99 i will have four,  and will need to sell a couple  of them with my A77 and A700.   Obviously i would like to keep the best one.  to do the exercise of fully charging and running them flat taking photos would be a challenge in itself.

Brian,
I will be watching to see if anyone comes up with an answer but I am one step ahead of you as I marked mine. :grin: :grin:  It is so variable as how often do you look at an image after taking it and what focus method do you use etc?

With my old (sorry Gordon) A700 I bought a cheapie no brand as a spare and all was going well until the critical time, we were on a dolphin spotting cruise in Western Australia a few years back and I popped in the spare.  It took three shots and that was it.  On recharging, it said it was full and took two shots back in the camera before I pitched it.  I have only bought Sony branded ones since..... john

I started with an A200 about 8 years ago, and my collection grew to a height of A200, A700, 2x A900 with a total of I think 8 batteries - 7 with Sony branding, 1 without (I am not sure if all 7 were genuine Sony).

I now have 'just' the 2 x A900, and 6 batteries (2 in VG + spare for each), and have no idea which of them these are (other than 1 being the unbranded one, as I sold both the A200 & A700 with apparently genuine batteries) - and have not noticed any real difference in capacities.
If I shoot a lot, sometimes it switches to the second battery in the grip.
I take the spare because it takes very little space, and the long life means I sometimes forget to check the levels of the batteries in the grip before setting out, so even if one is empty and the other partly drained, I still have a days shooting life :)

Keeping the battery constant through the Alpha range is one of the best moves from Sony - I have friends who use 'other brands', and a new battery for each new model is one of their biggest gripes.

I have An A700/A850/A77 all with V. Grips. Therefore I have two original Sony batteries in each, #1,2,3,5,6,and 7 plus another 6 fakes #4, 8, 9, A, B, and C. I use a Sony AC-VQ900AM which can charge two batteries at a time and it indicates the charge left in Hours and minutes. The fakes I do not use as they have no chip in them and do not switch over correctly in the V. Grips. I do keep them charged for emergency use. As you can see from the chart below, even the batteries that came with the A700 are still in good shape. Sony claims that this charger optimizes the charging.

Batteries for my A7 are all fakes. Not having a grip for the A7 I felt fakes were adequate.

This is a picture of the chart I use to keep track of them. occasionally, after charging I mark the time left in each.

so if i run the battery flat and time the recharge, that could possibly give me an indication of the better batteries - longer charge = longer use time?

My charger, the Sony AC-VQ900AM gives the time for each of the two batteries (that is the time that it will run a camera that is turned on and being used). It must be an approximate time as all Sony camera/lens combinations use more or less power.

A regular charger Sony BC-VM10 only shows a Yellow light and when it goes off, your battery is charged to its mazimum. However you will not know how strong the charge is, or how long it will last. You are correct though, You could manually time a new battery and compare that with an older battery and have a reasonably accurate estimate of the batteries condition.
