The next time you use the Continental drain the battery completely and then recharge it fully. During the next use drain the battery completely again and then again recharge it fully and then use it for at least an hour. Do not leave it fully charged and not used. Do it a few times each time you use this amp. This procedure should help counteract the 'memory fatigue' of the battery. If the serving time of the battery is still one hour short then that means that the battery starts losing capacity to hold the electric charge, probably due to the effect of aging caused by excessive heat. When it gets down to three hours then it is time to get a new battery. The battery of the Continental is glued in its place and you would have to ask ALO Audio if they can change it, but depending on how often you use this amp you still have about 2 years of use ahead. ALO Audio should make a better design related to the battery of the Continental. The ALO Audio does not want people poking into the insides of this amplifier. Probably ALO Audio thinks that the manual would encourage the people to do so.
