Battery lifespan?
- Thread starter Photo
- Start date
I bought them 2,5-3 years ago, don't know manufactoring date! I use a DY3... Do I have to buy more stuff to measure internal resistans??
In worst case I store them max 20hrs fully charged when an assignment has been canceld.
The Tenergy 5-in-1 Battery Meter does check the IR. It is not intuitive but following the instruction will work.

Do you have this model? Bought many on Amazon which claim IR measurement, but they do not? Sky RC D100 v2 I had to get in the end.
Yes, I do have a couple of them. The older version did not measure IR. The newer ones will measure it.
Maybe I will do another crumby video.
bought three different types which all claimed to read IR, bit none did, hand for checking voltage in the field.
saw this on a previous thread, bottom line the third party sellers gave false information.
It's a good start. Will give an indication that cells are close to the same voltage etc. But IR is like a blood test, will reveal a lot more than what's on the outside.

How does rising internal resistance of a battery affect performance. Sulfation and grid corrosion are primary contributors.

You can find the manufacturing date by looking under the flap. There are several digits displayed after a letter. The first 8 digits is the date in day/month/year format. It will prolly be something like B01042016xxxxxxx which will represent 01 April 2016I bought them 2,5-3 years ago, don't know manufactoring date! I use a DY3...
