decided to try a little experiment
. taking my old school
non intelligent cheapo battery charger and connecting it to my test bench battery. this charger never charges past 14.2 volts no matter how long it charges. i added a 1n5404 diode inline with the pos cable and immediately the voltage started to climb. peaking after a few minutes at 14.8 volts. a.6 volt increase which makes sense. next i decided to try adding another diode and again the voltage increased although not to the same extent. after a few minutes voltage reading was 15.15V and measuring current
with my ampclamp meter current
has settled between 900 milliamps and 1 amp.
so my thinking is that in theory and practice i can raise the voltage with this simple trick in order to equalize a battery with a non equalizing charger.
next test i guess is to try doing this same setup with an intelligent charger.
