Lead-acid battery discharge cut-off voltage

The discharge cut-off voltage of the lead-bismuth battery varies with the discharge current. Its value is not fixed.

Assuming standard capacity of lead-acid battery discharge current for the C (60 ah battery such as capacity, C = 60 a) :

When the current I = < 0.05 C, monomer battery cut-off voltage of 1.9 V, The 12 v battery discharge cut-off voltage of 11.4 V.

When the current I = 0.1 0.3 C, monomer battery cut-off voltage of 1.8 V, 12 V battery discharge cut-off voltage of 10.8 V.

When the current I = 0.4 0.5 C, monomer battery cut-off voltage of 1.75 V, 12 V battery discharge cut-off voltage of 10.5 V.

When the current I = 0.6 3 c, monomer battery cut-off voltage of 1.6 V, 12 V battery discharge cut-off voltage of 9.6 V.

The termination of the single battery voltage of 2.7-2.8 V, that is to say, the charger (no-load) highest voltage is 16.8 V. Because of the uncertainty of the power supply impedance and battery internal resistance, the voltage can also be a little higher, but it must be according to the actual situation of the power supply and battery charging strict monitoring. Otherwise it's easy to put the battery is bad.

For the power supply, light, the output is impending, did not use electrical appliances.

Low battery voltage of 10.5 v will charge, battery power can't put down, put out has a great influence on the battery life

After discharge of lead-acid battery, recharge, open circuit voltage drops too fast

Because power outages in the evening, the electric vehicle battery removed a piece of a bulb lighting (12 V), forget to turn off, after 2 days up to find the light bulb is not bright, remove the light bulb with a multimeter to measure voltage is only about 7 V, the charger is used after separate batteries, when voltage around 14 V, remove the charger, battery pack and the three groups together again, but this is only the battery voltage is always less than the three battery 0.5 V, and after discharge the battery to restore capacity will need to recharge.

When you charge to 14 v voltage to online, but in fact are not overcharge.

Suggest you separate to recharging the battery charging voltage with constant voltage 15 v had better, time control in 16 hours. Remember, is a "constant pressure" charge.

The other three batteries in accordance with the 12 v constant voltage charging the 15 hours, so we can put the battery level.

You are the only transition pass electricity, the battery can cause damage, sulfide, general sulfide it is difficult to restore by way of charging. So cannot return to the other two. Upstairs advice can a try, dead horse move! The

Cell represents the cell's cell, each cell voltage is approximately 2V; 12V cell has 6 cells, the termination voltage is 6 times the cell termination voltage; 6V battery has 3 cells, and the termination voltage is 3 times the cell termination voltage. Others like this.
