Recommended aftermarket battery for Sony a7r iii?

[Kirk_C]

I would need 5 batteries. That's why I want to save some money on the batteries.

You may spend less money but you're not going to save anything. You're going to get less for less.

Sony's batteries are outstanding. Every review raves about them.

Note that there are reports on Amazon that the Wasabi battery returns an "incompatible battery" error message.

I let myself get talked into a Julio battery when I recently purchased my A7r III.
It wouldn't charge initially, then eventually seemed to take a charge. When I went to use it a few days later it threw an incompatible battery error and I've sent it back and demanded a genuine as replacement.
