If the battery is more than two years old, replace it.
If that's the original RCM, send it to tighed1 to be refurbished

Replacing a battery after two years is probably a waste of money, take the charged battery to a auto parts outlet and have it properly tested under load.
Suggesting the replacement of the battery of that age is not constructive, if it does not prove to be the cause of the problem are you willing to reimburse the man for the waste of money.
A battery could fail after one day, never the less get a battery load tested before replacing it.
