Specifications Contact Us Ordering Guides. Sun Nov 15, 3: These rechargeable batteries do discharge by themselves rather quickly. A bit over a year.

Make sure to add a 47uF capacitor at the HT output, it will help. Say days to bring it from academic numbers to real life or about. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.


Thus, it limits us on internal discharge more than counting pico current.

HT78XX — 500mA TinyPower(TM) LDO

The applications mentioned herein are used solely for the purpose of illustration and Holtek makes no warranty or representation daatsheet such applications will be suitable without further modification, nor recommends the use of its products for application that may present a risk to human life due to malfunction or otherwise. He writes about unsoldering the LEDs and their resistors. Based on 3 days of logging it seems like it will run for about 24 around 12 days total before the batteries reach the 2.

It’s capable of running on 0.

HT78XX — 500mA TinyPower(TM) LDO

Check out a LiFePO4 cell instead of the lithium ion cells. I’m not sure where I got the mA figure from, maybe the seller Anyway it should be fine, it’s only receiving, not transmitting, we’ll see It’s annoying me for a lo[…]. Further thoughts on power saving: Thanks for the tip! Still a big improvement over not sleeping at all I guess, but it won’t last years.


I’ll list my admittedly limited data and open my thingspeak channel when I get home. Look at my intro story about ESP-Basic it has a s[…]. Have you read it? From that I can gauge device lifetime based on cycle frequency and available battery capacity.

Still not bad for a 30s log cycle. It has a lower voltage and does not require a regulator to power the esp. I had a Microchip part that was rated for mA and it worked much of the time, satasheet I did experience problems. We are a strong Community of developers, hackers, and visionaries. Current limit is measured by pulsing for a short time.

The guaranteed specifications apply ht77833 for the test conditions listed. Submit a new text post. Added info below and revised the lifetime from 24 to 12 days, because the cutoff for 2 batteries is 5v not 2. Since my other projects involve current hungry led strips, I’m probably sticking to LiIon for now.
