🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

1 review for KYF36UAA 1500mAh 3.8V Li-ion Battery for KYOCERA KYF36 KYF37 Flip Phone

  1. M******* (verified owner) –

    Needed a new battery for my old KYF36 flip phone — the original one wouldn’t hold a charge anymore. This KYF36UAA is a direct replacement, fits perfectly. Phone powers up like new, battery lasts a couple of days with light use. Great to have this classic phone working again as a backup device. Shipping to Greece took about 3 weeks, which is fine for international delivery. Very happy with it.
