Ancient battery restored
Following on from yesterdays discovery – this shows a rusted up ancient alkaline battery being restored. See Laserhacker.com for the SJR 3.0 circuit. My version here uses 4x ferrite rings from the cabling of old CRT PC monitors. 600 winds Secondary as the first layer, 150 winds on top. Transistor is a C4439 – 1.8W with 8W maximum. Input is 11V from a rejuvenated cordless drill pack. The battery, made by Vinnic, had 0.009V on it. I missed the start up of rejuvenation unfortunately, but, with a 1 minute connection to the output HV of the SJR 3.0, it shot up to a mispronounced 9.8V ! The coil began to sing, with a slightly varying high pitch of low volume. After about a minute it was disconnected and the level fell to 1.05V…but…then started to climb !!! It climbed like battery recovery, yet had started at 0.009V – I have no idea at this point why it would do so. The 9.8V situation is intriguing too. It settled out at 1.25V. Next, it is shown running a blocking oscillator (air wound tapped coil on the outside of a water bottle cap). An hour now since starting the run, it’s still going 🙂 Br0ns0n77 over at Energetic Forum has replicated the charging abilities shown yesterday and found them to correspond with my findings…cheers Br0ns0n for doing so 🙂
