Brand new battery (AJC ATX20L) from a Canadian Supplier called Battery Clerk.
Battery is 12 V, 18 Ah, CCA 270 A, AGM technology.
Installed in bike 1987 K100 RS, with no ABS and no alarm on bike. Charge topped up with NOCO charger.
Over three days 12.8 V drops to 12.3 V then on day four it is sitting at 10.5 volts! Used a Fluke meter to verify the reading. Only load on battery would be the BMW digital clock and a digital Voltmeter readout plugged in to the 12 V outlet under the seat.
What am I missing?
