Remember that it does'nt take very long at all for lead acid batteries to weaken requiring a good long slow charge .
Also lead acid batteries that seem dead or actually are dead can more often than not be messaged back to life . With a battery taking no charge . leave it on the charger and and it will slowly take more and more current the longer it's charging of course to a point. Another way which IMO is better is to shock charge it with Your vehicles charging system using 2 pair of jumper cables . Charge for maybe 10 or 15 min then hook up an dc electric motor or headlight and drain down for 3 to 5 min then charge from car for maybe 30 min then drain for 10 or 12 min if it has that much in it. repeat this cycle 4 or so times increasing charge and drain times some each time and by now if battery is going to come back all the way You'll know because You can power things good batteries can , So go ahead and slow charge (2 amps) for 36-48 hours of course filling with "Distilled" water only and keeping full throughout this process
