OPINION

This case is an appeal in a products liability action of the dismissal of Appellant’s punitive damages claim against Appellee Duraeell and the grant of Appellees’ motion for summary judgment.

Appellant liana Cohen (“Cohen”) improperly inserted (backwards) one of four D-size batteries made by Appellee Duracell International USA (“Duraeell”) into a small portable fan made by Appellee Vectacor Incorporated (“Veetacor”). She did so having been familiar with battery warnings 1 and aware of the danger that improper battery insertion could pose. Despite the battery’s improper insertion, however, Ms. Cohen continued to use the fan because the fan seemed to operate in a normal manner. A day later, Ms. Cohen fell asleep for twenty minutes with the operating fan placed on her stomach. Two of the four batteries leaked 2 onto her abdomen, resulting in severe injury, disfigurement, and pain.

Given this background, Appellant Cohen seeks to recover under two theories: negligence, based upon alleged design defects and inadequate warnings, and strict liability, based on the firms’ introduction into the stream of commerce of allegedly defective or unreasonably dangerous products. J.A. at 667. In addition, Cohen seeks punitive damages from Duraeell on the basis that the battery maker demonstrated reckless disregard by not incorporating a design change to prevent leaking in the wake of hundreds of prior such incidents.

The District Court, Nickerson, J., dismissed Appellant Cohen’s claim for punitive damages against Appellee Duraeell because the claim relied on allegations of “reckless disregard” that cannot meet the Maryland standard of “actual malice” as a matter of law. J.A. at 237. After excluding Appellant’s expert testimony, Judge Nickerson then granted Appellees’ motion for summary judgment, finding that Appellant failed to establish a defect in either product and, even if such defect were established, that Appellant’s contributory negligence barred recovery. Appellant now appeals both of these decisions. Because we find that Appellant fails to prove any defect in the products involved, we affirm.

LEGAL STANDARD

The grant or denial of summary judgment is reviewed de novo. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986); Higgins v. E.I. DuPont de Nemours & Co., 863 F.2d 1162, 1167 (4th Cir. 1988). In making this determination, “the court is required to view the facts and draw reasonable in *375 ferences in a light most favorable to the nonmoving party.” Shaw v. Stroud, 13 F.3d 791, 798 (4th Cir. 1994) (citations omitted), ce rt. denied, 513 U.S. 813, 115 S.Ct. 67, 130 L.Ed.2d 24 (1994); Felty v. Graves-Humphreys Co., 818 F.2d 1126, 1129 (4th Cir. 1987).

Summary judgment is appropriate where no genuine issue exists as to any material fact and the moving party is entitled to judgment as a matter of law. Fed. R.Civ.P. 56(c). A genuine issue of a material fact exists “if the evidence is such that a reasonable jury could return a verdict for the nonmoving party.” Anderson, All U.S. at 248. Where the record taken as a whole cannot lead a rational trier of fact to find for the nonmoving party, however, then no genuine issue exists for trial and summary judgment is appropriate. Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 587, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986).

Once the movant has met its burden, “the nonmoving party must come forward with specific facts showing there is a genuine issue for trial” in order to defeat the summary judgment motion. Matsushita Elec., 475 U.S. at 587. Under Rule 56(e), the plaintiffs must introduce admissible evidence demonstrating a genuine issue of fact on each element of their claims. Fed. R.Civ.P. 56(e). Yet, the “mere existence of a scintilla of evidence in support of the plaintiffs position will be insufficient,” Anderson, All U.S. at 250, for “[o]ne of the principal purposes of the summary judgment rule is to isolate and dispose of factually unsupported claims or defenses.” Celotex Corp. v. Catrett, All U.S. 317, 323-24, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). DISCUSSION

Turning to the case at hand, we find that Appellant fails to meet her burden on summary judgment. In order to prevail, a plaintiff in a products liability action must proffer “proof of a defect in the product, whatever the theory of liability.” Riordan v. Jones, 793 F.Supp. 650, 651 (D.Md. 1992). Because Appellant Cohen fails to prove such a defect with regard to either the batteries or the fan, no reasonable jury could return a verdict in her favor on any of the claims asserted.

Between negligence and strict liability, Appellant’s stronger theory for recovery is under strict liability because “the plaintiff is not required to impugn the conduct of the maker” but is merely required “to impugn the product” by a showing that the product is defective in a way that is unreasonably dangerous. Prosser & Keeton on Torts § 99, at 695 (5th ed. 1994) The present-day elements to a claim in strict liability under Maryland law originated in Phipps v. General Motors Corp., 278 Md. 337, 363 A.2d 955 (1976):(1) the product was in a defective state when it left the control or possession of the seller, (2) the product was unreasonably dangerous to the user or consumer, (3) the defect was a cause of the injury, and (4) the product was expected to and did reach the consumer without substantial change in condition. Id. In this action, however, Appellant fails to demonstrate any defect in either the batteries or the fan. As a result, the granting of summary judgment in favor of Appellees is correct because Appellant’s claims necessarily fail. 3

Given the millions of batteries in this electronically-driven world, we make no shocking revelation in noting that some consumers will insert batteries improperly no matter what safety precautions are taken. To prevent these occurrences, Appel *376 lant Duracell has included conspicuous warnings not only on battery packaging, but also on the individual batteries themselves. Moreover, in the event that a consumer improperly inserts Appellee’s battery notwithstanding the warnings, the product was designed with a venting procedure whereby the batteries leak in order to prevent even greater hazards, such as battery explosions. See Footnote 2, supra. The latter scenario is precisely what occurred in this case: by leaking, the battery performed exactly as hoped so as to prevent an explosion, and even greater injury, from occurring.

Such safety features do not render the product defective, and they certainly cannot be said to approach anything unreasonably dangerous. Indeed, Appellant admitted to having read battery warnings and having known of the danger posed by improper battery insertion. Moreover, the uncontroverted evidence 4 indicated that the Duracell safety design was the “pinnacle” of the industry and conformed to all government standards. J.A. at 304. Without evidence of a defect in the design or manufacture of the battery, Appellant simply cannot recover in either negligence or strict liability against Appellee Duracell.

Appellant also fails to set forth a prima facie case with regards to Appellee Vectacor because Appellant again fails to give any evidence of defect. The product contained adequate warnings: the fan itself had elevated markings molded into the plastic nearby the battery compartment, and the fan’s instructions directed the user to insert the batteries “as the diagram in the fan shows.” Id. at 666. Appellant’s own testimony not only indicates that these markings were sufficiently visible, but also that she actually noticed them and attempted to insert the batteries as they directed. Id. at 412-13. Given the sufficiency of the notice provided by Vectacor regarding battery insertion and the proper functioning of the device, we find that the fan was not defective. Appellant therefore necessarily fails on both theories of the case that she appeals against Appellee Vectacor.

Because Appellant fails to make a prima facie case against either Appellee, the additional issues discussed below are rendered moot. 5 Accordingly, the judgment of the District Court is affirmed.

AFFIRMED.
