Testing rechargeable batteries in my 06044M sensors. I purchased EBL 1100mHa  batteries for my sensors. These are Low Self Discharge Ni-MH batteries. I know that Acurite does not recommend using rechargeable batteries but I have done the research and I think these are going to work fine. So far they are working fine.  The display on the sensors shows that the batteries are not fully charged but that is because rechargeable batteries are 1.2v where alkaline's are 1.5v to start, This does not affect the report on myacurite... they are still showing good. The power curve on the rechargeable batteries is better than what alkaline batteries offer. I think that that battery chemistry has really improved over the years and warrants a second look. I did purchase a Opus Charger so that I can tell exactly how the batteries are preforming. I did this because we spend $80 a year on batteries and see this as an opportunity to save some money.

So far so good, 2 weeks now and all my sensors are working fine with the rechargeable batteries.

I take it 1., you are not in a cold climate and 2., your sensor is in a location where you can easily access the batteries. Energizer Lithiums last 3 years, and we have -35C temps here. Good luck though, the progress in li-ion batteries is the focus now. Not so much the Ni-mh.

I am in MI, but i am only using the rechargeables in the indoor sensors. I have 10 sensors indoor and plan to add more , this will save money provided it continues to work. I figured it was worth a try for sensors i can easily get to. Not going to do it for the one on the roof....

For the value I get from quality lithiums, I wouldn't even consider rechargable batteries for outdoor use.

I think the new low self discharge nickle metal are much, much better than the old batteries. Time will tell if i am right or if i wasted $20. I also purchased a quality charger so that i can control the charge rate. All the fast chargers just shorten the life of the battery. lithium batteries are great but expensive. Too bad the sensors can’t use the 3.7 lithium rechargeable... that would truly be the best.
