Battery Charging differences: Lead Acid vs. Ni-Cd
During your aircraft familiarization course differences in battery types are pointed out with their specific properties (charge, thermal runaway etc.). But what about charging the battery? Is there any (technical) difference charging a lead-acid battery versus a Ni-Cd (apart from heat development regarding the Ni-Cd)? Would your car battery charger work on both types? Is it basically [Battery Voltage] * 1.2 = Charging Voltage ?
