Hi,

First of all thaks for your orientation about it, I would like to tell that we are in battery business at the first starting business we had someone to do battery test, now, time has changed and myself must to perform it. I can drive this topic in two sections theorical and practical ones.

Theorical one -

What I do know is that battery discharge must reach 80% of nominal voltage in order to avoid battery damage, i.e. 36 V battery will be 28.8 VCD between positive and negative pole, which means 1.6 VCD in each cell. good point you make me remarkable is to take voltage and SG readings to get a battery cells reference ( I will do further).

From your lines I understood that cells are damage if they reach 1.6 VCD along battery deliver power which means any cell above it will work fine.

Questions:

1. what to do about Amps will drain the forklift in an operational condition vs. battery power to expect the worling time in a battery tested? or what is the way to calculated it?

2. i.e. I charged fully a battery and then I discharged it using a electronic discharger , after 177.44 minutes draining 80 Amps(constant current draining) it stopped. what to do in order to know the battery lasting time in a operational condition if the machine is not a constant current device?

Note: Battery dicharger we have will stop automatically at 240 minutes or when cells reached 1.75 VCD.

Hands on -

in a scheme I had to have to change a cell -
1. Do you know where I can find the driller bit for posts? also, we will need the cable terminal molds which will attach in the cell post, do you know where to get them? do we need to make them in a machinary shop? if we so, Do you know the molds specs to go to the shop with it?

All above is what I got when a battery thechnician worked with us.

Let me know what we will go next to get batterry well tested and/or try to get them back in working life.

Kind regards,

Luis

Fact of the week
The word "robotics" was coined by Russian-born American science-fiction writer Isaac Asimov who first used the word in 1942 in his short story 'Runabout'. He characterised robots as helpful servants and as "a better, cleaner race."
