Both of those are 20-amp batteries. A .25, assuming no voltage drop, pulls a little over 16amps. 15 on a fresh battery, if you want to be realistic. So yes, it's a reasonable fit for either of those batteries.
Generally, you can even push slightly past the continuous limit. It's just not advisable as it leaves you no safety margin, should something go wrong and tends to lead to diminished charge cycles, more voltage sag, and capacity loss. That's why the general thinking is to stay a little below the continuous rating, where the battery is known to run at a safe, none-too-damaging temperature even if it is discharged at that rate continuously.
The general rule of thumb is that if your battery is getting extremely hot, whether you're under or over the amp limit, you're gonna have a bad time. So long as they are generally running cool, you shouldn't have too much to worry about it.
Brush up on your ohms law and you won't have to be so uncertain about how hard you are pushing your batteries. Know what your batteries can handle according to actual testing, not just published ratings. When in doubt, use

this chart as a starting point for researching different batteries. Google is your friend for learning more about specific batteries and how they hold up compared to the numbers as well as other batteries.
Remember, it is your responsibility to use the tools available to you to put your safety into your own hands.
