## Questions & Answers

**Q: Do batts, work in honeywell spotmatic - F?**
A: Probably not. None of mine worked and they didn’t take them back.

**Q: Would this battery work in an Olympus 35 EC 2?**
A: Not sure that it could work. It did not work for the purpose I bought it for. Thus one needs to ensure that the dimension of the battery is a best fit for the one it will replace.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works in my Pentax Spotmatic SPII
*by S***. on December 30, 2024*

This battery works perfectly in my Pentax Spotmatic SPII. If you put it in and the meter works in reverse, flip the battery around. That's a fun little quirk of the Spotmatic meter that I'm glad I read about in advance, because I would have been so confused when it happened to me!

### ⭐⭐⭐⭐⭐ Spotmatic Works Again.
*by W***Y on November 7, 2024*

Bought this for an old Pentax Spotmatic and it works. I haven’t used it long enough to know how long it’ll last. It’s not like I’m using the camera constantly so I imagine it’ll last long enough for my purposes. No complaints.

### ⭐ Questionable seller
*by H***R on August 2, 2025*

Would not buy from this seller, battery was dead, checked with voltmeter, asked for a refund, no response at all.
