Review on 🔌 Kawish Full Automatic Car Battery Charger 12V/24V 10Amp Intelligent Pulse Repair Battery Charger: Ultimate Power and Convenience with Terminal Clean Brush by Tim Purdie

The world of anti aging batteries seems to be pretty big, mostly fictional, but I'm seeing great success with this charger on an 8 year old Concord Aircraft AGM battery. The battery suffered from low starting current and low voltage when fully charged (12.4-12.5V). This charger charges at a constant 14.26 volts, which I consider to be the absolute maximum before the battery starts boiling water. I left this charger plugged in for a few weeks and regularly switch it to MANUAL charge mode which is around 16.4v for 10-20 seconds. You can hear the electrolyte boiling at this voltage so I'll be brief as the batter is sealed and engineered to reabsorb the gases. At last check, the resting voltage (two hours after pulling 20mAh) is 12.85V. While some batteries wouldn't be in the 13.1 range, it's much higher than I expected. My plan is to configure an Arduino controlled timer to give power for short bursts (5-10 seconds?) throughout the day. [Note: Always follow the manufacturer's recommendations for replacing aircraft batteries on certified aircraft. Capacity and duration are critical issues.]
