Lead acid battery and lead acid battery charger -- specs don't match, but can I use them anyway?
Connect it and use a multimeter to see the voltage and then also check the current - if it is below 5A and behaves nicely then I would assume it is doing fine.

If it hammers the battery at 10A and does not do any charge control then you need another charger.

If you don’t have a meter to check what is going on, either get one or stop playing.
