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.

Is A Higher Ah Battery Better?
For example, if you see a 10 Ah battery, it means the battery can supply ten amperes for one hour before draining completely. By extension, this same battery could also provide five amperes for two hours or two amperes for five hours. It''s important to note that higher Ah batteries typically have more cells inside them and appear in larger packs …

Lowering amperage a good thing? | Tesla Motors Club
This means that the current sent to the pack by the charger is split 46 ways. Charging at 240V and 32A results in about 22A into the battery pack. Divided 46 ways that is 0.47A charge into each cell. Dropping your charge current to 20A would drop the charge current to 0.29A So no dropping the charge current would have no effect on …
