I have been using AA Energizer Lithium's in my thermal scope and have been pleased with the length of use but the price of them hurts a little. Regular alkaline batteries are lame and only last for a short period of time. Has anyone used rechargeable NIMH batteries in a thermal yet to see how they work out?

Would not recommend using rechargeable in any thermal gear.

Don't do it - and ALWAYS take the batteries out when not in use.

Have you considered the new LIPO batteries?

Why not use rechageable in thermal?

My manual states that rechargeable batteries are fine. I'm hearing some "no don't do it's" but not the why. As I understand it, FLIR ships several models with rechargeable batteries in them from the factory.

Don't know of any TWS manufacturer that allows the use of NIMH rechargeables, the FLIR units you mentioned use Li-ion, not NIMH.

If your specific TWS manufacturer states that they are fine for you to use in your unit, why did you ask about using them in the first place?

I'm asking because it states rechargeable batteries are fine it just does not specify if they should be Li-ion or Nimh. Until I started researching the subject today, I didn't know rechargeable Li-ion batteries existed. I am leaning toward Eneloop Pro's by Panasonic.

You'd best contact the manufacturer of your unit with your questions before using any rechargeable battery in any thermal device.

As a rule, it is a NO-NO.

Apparently, several of the major manufacturers embrace the concept of rehargeable batteries. As noted, some FLIRs have built in rechargeables. The FLIR R series accepts external battery pack such as the 15,000 mAhr Anker SkyPup has used. Armasight sells external battery packs that allow for the use of 18650 rechargeable batteries. UNV sells external power supplies for ATN THOR units that ATN has approved for use that use 18650s. Pulsar specifically allows for the use of rechargeable batteries.

I would add that Pulsar not only "allows" for use of rechargeables, it sells them for use with their gear.

I have been using Li-on batteries in virtually all of my gear for a long time with zero issues. The idea that there is an issue with them as it pertains to the gear is bunk. What scope do you have ntxtrapper?

Edit: I would like to make it clear that all of mine are used with external rechargeables, not rechargeable AA's or CR123's.

Pulsar sells two external rechargeable batteries for the HD 19. The EPS3 (2.4Ah) and the EPS5 (5 Ah). Or you can build your own pretty easy and cheaper.

Wow! Thanks dfwroadkill. All these bad answers on here and you come to the rescue with exactly what I need. I assume this this plugs in the DC jack? I use it at work way too much to use throwaway batteries. It's on several times a night 4-5 days a week. fugitive apprehension, clearing a structure with no lights and seeing if a car has been used recently are just some of the uses I have found for it. Thanks again.

As previously noted, Lithium ion rechargeables are utilized in the FLIR RS series as well as their PS and LS series, these are NOT NIMH rechargeable batteries as OP originally inquired about.

18650 batteries are Lithium Ion, not NIMH rechargeable batteries.

DO NOT use any rechargeable batteries in any TWS unless the manufacturer specifically states which ones are acceptable to use.

And, as usual, it pays to contact the TWS manufacturer directly for information instead of trying to find it on the internet.

Remember, NIMH is a NO-NO in spite of what others may say.

There were not any bad answers in this thread, just bad questions.

Cool then unless you know, don't post "Would not recommend using rechargeable in any thermal gear" unless you know about the subject. I came here to seek information and guidance from folks who have the knowledge. Luckily someone who does, read my post and knew exactly what I needed. Apparently they use thermal devices a lot like I do.
