Purchased this replacement battery in April of this year as I needed a spare. Just started using the battery and am having a problem with it staying charged. Since it is a new battery I feel this should not happen. How do I go about getting a re;placement at no charge???Please contact me asap as this is used for work purposes and is needed for everyday useThank you for your prompt reply.Susanne
