No. You will never get the full capacity of your new battery if you don't start it off with a big enough charger. Check the manual for the battery. Trickle - not enough.

https://www.yuasa.co.uk/info/motorcycle-and-powersport/battery-selection-activation-charging/Do not use a high-amperage charger to reduce charging time as it will void the battery warranty
To find the recommended charger current output in amps for a specific battery, divide the battery
amp hour rating by 10. For example a 14AH battery should be charged at 1.4 amps
(14AH รท 10 = 1.4 amp current). Select a battery charger that comes closest to the value of that
figure. All Yuasa powersport batteries have the amp hours printed on the front or top of the battery case.-Mike

Many standard adjustable chargers with a 2 amp setting are just fine for that 1.4 amp recommendation. I think 10 amp is too high however.
But a trickle charger is not a good idea for the first and most important charge of the battery's life. It might be OK, but it might not.
Do not cover the cells with the plug strips before that first charge; there's a lot of breathing and fuming going on.

And make sure it's in a well ventilated area. |

Larry--Years ago I bought an inexpensive Black and Decker charger that allows me to set the charge current at 2, 6 and 12 amps, or maybe 2, 4 and 6. Get one and you will have it forever. I'm sure there are other chargers that will work similarly. Check Amazon. You would be able to charge your cars and other vehicles as well. Pick the current that is close to the recommended charge rate explained by Mike.
Good luck.
Greg

Definitely need a 2 amp charging rate. I tried my .75 amp charger/maintainer and it showed it was charged after a 10hr. charge but at the initial start, no go. Put 2 amp on until ready all was good.

Buy a charger that gives you the 1.4-2.0A you need to initially charge a new motorcycle battery. Like Fazer suggested, I would just get a typical car battery charger that can be switched to a 2A output, that way you can also use it for car batteries. The actual current will automatically drop as the battery is charging, i.e. the current meter on the charger will initially show 2A, but the needle will drop over time until the battery is fully charged. The 2A/6A charger Fazer recommends is okay, but I'd rather spend a little more money and get one with a 10A higher charge rate and a boosting function as well, giving it more capability with car batteries.
Get a good smart charger (not the cheapest thing you can find at Walmart) to maintain the charge on your motorcycle battery if you're not riding it for a few weeks or longer.

A 750mA charger will maintain the charge at whatever level the battery is at the time you hook it up, but it will NOT increase the charge. It's called a trickle charger for that reason. Do NOT use a 10 amp charger. A 1.25 amp, to a 2 amp max, is what you're looking for.
