Lester Electrical warrants each new Lester Battery Charger for defects in material and workmanship for a period of two (2)

years from the date of manufacture of the complete unit.  Repairs can be made at the Lester factory.  To do so, first obtain a
"Return Material Authorization" number by calling the Service Department of Lester Electrical 

(402 477-8988)

 or by e-mailing

[email protected]

 and send the defective unit with transportation charges prepaid to:

Lester Electrical
625 West A Street
Lincoln, NE   68522-1794   USA
Attention:  Service Department
RMA #                               

For repairs made at other than the Lester factory, Lester will provide only the replacement parts.  Defective parts should be

sent with transportation charges prepaid to the Lester factory at the address noted above.

If the unit or parts are found in the reasonable judgment of Lester to be defective in material or workmanship, repair or

replacement will be made by Lester without charge for parts or labor.  Repair or replacement will be at the discretion of Lester,
with replacements being made using current models or parts performing the equivalent function.  Labor charges other than
those incurred at the Lester factory are not covered under this warranty.  All expenses associated with delivering defective
items to the Lester factory and the expense of returning repaired or replaced items from the Lester factory to the owner will be
paid for by the owner.  All warranty work accomplished at the Lester factory will be completed with a reasonable time after
receipt of defective items.

This warranty does not cover any semiconductor parts, such as diodes, which are vulnerable to electrical overloads beyond

the control of Lester.  Warranty on parts not manufactured by Lester, which include, but are not limited to, timers and
ammeters, is limited to the period specified in the original manufacturer's warranty.

This warranty does not cover any charger that has been subject to misuse, neglect, negligence, or accident, or operated in

any way contrary to instructions specified on the charger case and in the owner's manual.  No claim of breach of warranty shall
be cause for cancellation of the contract of sale of any Lester charger.  Lester assumes no responsibility for loss of time,
inconvenience, or other damage, consequential or otherwise, resulting from a defective charger.  All implied warranties
(including merchantability) are limited in duration to the two years from date of manufacture warranty period.

Some states do not allow the exclusion or limitation of incidental or consequential damages; or limitations on how long an

implied warranty lasts, so the above limitations may not apply to you.  This warranty gives you specific legal rights, and you
may also have other rights which vary from state to state.

Lester's obligation under this warranty is strictly and exclusively limited to the repair or replacement of defective items.

Lester issues this warranty in good faith and with full confidence in the workmanship and quality of Lester products.
