Certainly, any date stamp gives an indication about the battery's age, but only if you manage to decipher it correctly...
Care to answer my question, as to how your battery tester might derive the
battery capacity from 5 minutes of testing?
Or did I get this wrong, and your battery tester only tests for maximum load
current capability and then goes to a pre-programmed lookup table and pulls
out the associated capacity, which is only an estimate of course?
When doing my daily load tests, I gain a thorough understanding about the
batteries ability to store the rated amount of Ah. In the process, I also get a
printout from the terminal voltage data logger set to one minute intervals, to
see how this voltage compares to the manufacturer specified discharge
characteristic @ the constant load test current. Note that this result is directly proportional to the battery capacity, provided the battery was at 100% full charge at the start of this 30 minute testing routine.
Just to satisfy your curiosity, no we don't charge for this load/capacity test.
