battery didn't fit. sent a polite email to the retailer and rep was an @ss about the whole thing. last purchase from ameridroid
Hi Cody,
We’re truly sorry to hear about your experience and that the battery didn’t fit as expected. We strive to provide helpful and clear support, and it’s disappointing to know we fell short here. For transparency, we’ve shared the email exchange below so others can see the context of our interaction:Cody’s Email:
'Good monring, i bought a direct replacement for my battery, two of them actually. and it doesn't fit, it's too long. i'm a novice with electronic batteries. what did I get wrong?'
Our Response (Brandon):
'Hello Cody, I would assume your batteries might not have been 18650 batteries? 18650 batteries are standardized in size, with a nominal diameter of 18 mm and length of 65 mm, hence the name '18650.' However, there can be slight variations: Protected vs. Unprotected: Protected 18650s (with built-in circuit protection) may be slightly longer (up to 68-70 mm) due to the added circuitry. Button Top vs. Flat Top: Button-top batteries have a protruding positive terminal, making them slightly longer or taller than flat-top versions. Manufacturing Tolerances: Minor differences in diameter or length (within 1-2 mm) can occur due to manufacturing variations.
For most practical purposes, 18650s are interchangeable in devices designed for them, but always check the device's requirements for protection type or terminal style. Brandon'
Cody’s Reply:
[A picture of the battery, no additional text]Our Follow-Up (Brandon):
'Hello Cody, Not sure the reason for the picture, but I can see that you received an 18650 battery which is what you ordered, do you have any other questions about the battery? Brandon'
Our intention was to clarify the battery specifications and ensure you received the correct product, as well as to understand if there were additional concerns we could address. We’re sorry if our response came across as unhelpful or dismissive—that was not our intent.
