I have a Triopo Speed Light TR-980N (one of these: https://www.giftsngadgets.com.au/pro...0&cat=5&page=2 ), which takes 4 x AA batteries. I initially just grabbed 4 alkaline Energizers out of the cupboard and it worked really well for maybe 20 or 30 photos, but now when I turn it on, it takes longer to become ready than the auto-off time of the flash, so the only way I can use it is to operate the buttons on the back while waiting for the red light to come on.

So when I was down at Woolies today, I was having a look at the batteries available and nearly bought some 2300mAh NiMH batteries, but then thought it might be wise to ask here for advice to make sure I get the most appropriate batteries.

I also noticed there are Lithium batteries available which say (among other things) "do not recharge"... why can we re-charge the Lithium batteries in our cameras, but not the AA ones??

Regards,
John
