Battery options for Sony RX10-IV? (1 Viewer)

[Western Tanager]

I bought some Kastar batteries for my camera but some them seem to not hold a charge very well.

Are there other better battery options besides the Sony original which is quite expensive?

I've been using Watson and Green Extreme replacements batteries for a couple of years with no issues. I also tried Wasabi batteries, but the two I had swelled up. None of the replacement batteries have held a charge as long as the OEM batteries.

I have several brands, but tend to use the same ones. So I have no true idea about which are better or worse. Patona has held its charge rather well. Duracell is probably the one that holds its charge best. But the camera is a power "gulper". So I tend to take along spares all the time. Original ones are not that much better, if at all. I think they may have been at the beginning. One of my two Sonys is definitely better than the other one, though I bought them together. I have one other one that seems not to have a brand name. It only says Li-Ion BATTERY. It has 1500mAh instead of the customary 1020 to 1030.
