I'd be surprised if there was. When you say the battery is "going bad," does your camera show that it is at the end of its useful life, or is it just performing poorly but is a relatively new battery? If the latter, has it been stored in a totally charged or totally discharged state for long periods of time, or at high temperatures? LiON batteries don't do well if stored fully charged at high temperatures. That's why batteries in laptops that are kept plugged in to their chargers tend to wear out before the typical 3 years, as the laptops, if they are running, get hot and the batteries are in a fully charged state.
On the other hand, new batteries benefit from going through a few charge/discharge cycles, which seems to enable them to get to full capacity.
