LIMITED POWER OF ATTORNEY

Know all by these presents that the undersigned hereby constitutes and
appoints each of Karen J. Yodis, John Yarbrough, and Joseph G. Lewis,
signing individually, as the undersigned's true and lawful attorney-in-fact
to:

       execute for and on behalf of the undersigned, in the undersigned's
capacity as an Officer of EnerSys (the "Company"), Forms 3, 4,
and 5 in accordance with Section 16(a) of the Securities Exchange Act of
1934 and the rules thereunder;

       do and perform any and all acts for and on behalf of the undersigned
which may be necessary or desirable to obtain filing codes, complete and
execute any such Form 3, 4, or 5 and timely file such form with the United
States Securities and Exchange Commission and any stock exchange or similar
authority; and

       take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of benefit
to, in the best interest of, or legally required by, the undersigned, it
being understood that the documents executed by such attorney-in-fact on
behalf of the undersigned pursuant to this Limited Power of Attorney shall
be in such form and shall contain such terms and conditions as such
attorney-in-fact may approve in such attorney-in-fact's discretion.

The undersigned hereby grants to each such attorney-in-fact full
power and authority to do and perform any and every act and thing
whatsoever requisite, necessary, or proper to be done in the exercise of
any of the rights and powers herein granted, as fully to all intents and
purposes as the undersigned might or could do if personally present, with
full power of substitution or revocation, hereby ratifying and confirming
all that such attorney-in-fact, or such attorney-in-fact's substitute or
substitutes, shall lawfully do or cause to be done by virtue of this power
of attorney and the rights and powers herein granted.

The undersigned acknowledges that the foregoing attorneys-in-fact, in
serving in such capacity at the request of the undersigned, are not
assuming, nor is the Company assuming, any of the undersigned's
responsibilities to comply with Section 16 of the Securities Exchange Act
of 1934.

The undersigned hereby authorizes each such attorney-in-fact to
file any original or copy of this Limited Power of Attorney with any
institution or person or in any public office, including the United
States Securities and Exchange Commission.

I hereby revoke any and all Powers of Attorney executed by me prior
to the date of this Limited Power of Attorney that cover the subject
matter set forth herein.

This Limited Power of Attorney shall remain in full force and
effect until the undersigned is no longer required to file Forms 3, 4,
and 5 with respect to the undersigned's holdings or transactions in
securities issued by the Company, unless earlier revoked by the
undersigned in a signed writing delivered to the foregoing
attorneys-in-fact.

Any provision of this Limited Power of Attorney judicially determined
to be unenforceable or invalid for any reason shall be entirely
disregarded and such determination shall not affect or impair the other
provisions hereof.

IN WITNESS WHEREOF, the undersigned has caused this Limited Power of
Attorney to be executed as of this 2nd day of January 2025.

/s/ Keith Fisher
Name:  Keith Fisher
