So ultimately what is your conclusion between the 3?
I found this thread searching for any feedback on the Tenergy brand on Amazon. Looks like it is decent, so thanks. But now I am wondering about rechargables people are speaking of. I used to use AA and AAA rechargeable a while back but they were not that great. I think what I am missing is a really good charger. Any recommendations on chargers?
Edit: Found this, was hoping for CR123 also.
Rechargeable batteries have shorter run times than non-rechargeable. If you want the absolute longest run time before having to change out the battery, you need non-rechargeable.
If you don’t mind taking the time to change out the batteries in your sensors more frequently, then rechargeable batteries are an option.
I've had same luck with panasonic with cr123
My ultimate conclusion: buy rechargeables and stop filling landfills with dead single-use batteries.
Of the 3, they all seem to last fine in my uses. I don't record battery brand in my "Battery Replacement Dates" spreadsheet, so I don't know what I've had in the past. But I have all three of these in dozens of Iris v2 devices (47 contacts and 20 motions) and they've all lasted 18-24 months (at least). But as @Ken_Fraleigh points out, my Amazon Basics aren't what they are selling anymore.
But with the RCR2s lasting 18 months for me, I think they will be good enough to avoid the single use CR2s forever more.
For CR2, I bought one of the EBL set of 8 with the charger, which looks slightly different then what they now sell (that you linked to).
For rechargeable CR123As, I just bought these and they are arriving today, so I'll be installing them in a few hours.
