Hi i have curious problem of RTC timer not keeping sane during runtime.After few hours. the time goes absurd.like 3-148-2000 00:01:00 and then 33-38-2032 31:33:00 instead of 4-18-2022 13:39:56.
pretty clueless. any hint will be welcome.
thanks

What is the voltage of the battery on the RTC timer?

Which model of timer is it (adafruit#)?

Sir,
the voltage of the battery is near 3.2V dc. and model of timer is old RTC_DS1307.

The battery sounds reasonable @. 3.2v. Can you post a photo of the board top and bottom?

Sir,
The data shield is working fine now. Changed power supply of Arduino from adapter 5v to USB power 5v mobile charger!
Now the data collection is just as per requirement.

thanks
