This is generally enforced by limiting chargers to a max rate of 6 amps. However certain special conditions could allow a charger with a max rate greater then 6 amps to be used. |
I hate to disagree with all of you but if you read the Enersys application manual for our batteries it does clearly state the maximum charging rates on page 6. The confusion seems to be the fact that the bolted terminal line says 6CA. All the other columns are specifically amps. If you go to page 17 you will see the definition of CA and the line above with c-rate.
The actual max charging rate on our battery is 6 times the Ah rating or 6*17.2 for a max of 103.2A. Would anyone ever charge at that high a rate? I would expect not. If you look at the other columns in the chart on page 6, why on earth would you be able to charge at 75A maximum through a normal spade terminal and only 6A through a physically bolted connection. That just doesn't make any sense at all. The most important thing with these batteries is not the amperage that you charge at, it's the voltage which should be 2.35-2.45 volts per cell or 14.1-14.7 volts.
It's all about reading the manual correctly.
