BU-403: Charging Lead Acid
For your 7.5Ah battery, charge current should be below 1 amp. But a 2 amp or even 3 amp peak for a few seconds won''t do harm. So a 1 ohm resistor in series would be a good idea to start with, but measure the current by measuring the voltage over the resistor. If current is low enough, you can try using a smaller resistor like 0.1 ohm.
