10. MountingRecommendations˃ Provideproperlyspacedholesformountingaccordingtothespecifiedcelldimension

inordertominimizetheterminalsofthecellbeingmechanicallystressed.˃ Donotplaceanythrough-holesdirectlyunderneaththecellorinthecloseproximity

ofthecell.Allowatleast5mmdistancefromanypointontheouterdiameterofthecelltotheouterdiameterofanythrough-hole.

˃ Protective coating of components on the PCB is strongly recommended in order toreducetheriskofthecomponentsbeingdamagedinaneventofelectrolyteleakage.

˃ Provide at least 2mm clearance from the safety vent and do not position anythingnearthesafetyventthatmaybedamagedbytheventrupture.

˃ AssemblethecellonthePCBtakingintoaccountthatthecellmaynotbecompletelyhermetic during its lifetime. Electrolyte vapor and gases generated during normaloperationmayescapethepackage.
