To prevent that sensor Q1 is warmed up by its own current draw, I recommend adding a cooling rib of sorts. Setting up a webcam sight illuminator over your laptop's webcam will certainly “enlighten” your online conversations. Temperature compensation helps prevent overcharging, the LM334 temperature sensor should be placed near or on the battery.
The charger’s input voltage must be filtered dc that is at least 3V higher than the maximum required output voltage.
Would it be possible to modify the above circuit to produce a 14.3v charge and 13.5v float to charge a gel cell battery?

This curve is a real record for a standard 3 stages charging process, based on A100-24 model. Your use of this website constitutes acknowledgement and acceptance of our Terms & Conditions.
The charging current decreases as the battery charges and when the current drops to 180 mA the charging circuit reduces the output voltage to 2.35 V per cell, leaving the battery in a fully charged state. The comparator’s output controls the voltage regulator, and produce the lower float voltage when the battery-charging current, passing through R1, drops bellow 180 mA.

Open the regulator, replace the 56 ohm resistor marked as VR1, with a 100 Ohm trim pot via two tiny wires. One variation is to start a timer at "CVh" stage, when the timmer out, the charger will enter "Floating charging stage" automatically. I have more than one car and while not in drive I trickle the battery to keep at 12.9 V without charging element.

    Use a high current to get device, replacement of Ni-Cd with the electrolyte does not participate in the.
