BatteriesPlus review: duracell motorcycle battery and staff

Bought Duracell motorcycle battery approx 4 months ago new with battery tender from Battery plus.
Battery went dead with battery tender connected.
Called Battery plus store
Blake advise me to check connections, fuses, and alternator.
I checked. All good. Battery dead with battery tender connected.
I took battery out. Put on another charge which showed BAD.
Took battery to Battery plus store where purchased plus battery tender.
Blake tested battery tender. Which worked fine.
Blake tested battery. Showed 2 volts.
Blake would not replace till after testing 24 to 48 hours. Then since he was off weekend some will call you.
I waited past 48 hours. Past 2 full days. Blake had battery at noon Thursday.
No one called. So sunday called at 1130. 1.5 hours after store opened.
Gentleman answered phone. Asked about battery. He stated he had battery and paperwork in front of him. I asked the status he didn't know. He would have to call me back.
5 minutes later he called. He said he tested battery. There is nothing can be done. Battery is at 1.5 volts. He said anything under 12 volts there is no replacement or warranty due to outside source.
I asked what outside source. He could not explain. Then I asked how did you test. Then he admitted not testing battery.
I asked how do you not know the inside of battery does no have a defect. He could not explain.
Asked explain outside source definition. He could not explain.
Asked so no replacement or warranty on this battery. Answer no
I request battery be held pending this complaint and investigation.
PROBLEMS:
1) Don't call the customer after 48 hour. Keep in mind battery was there at noon Thursday. I called at 1130 Sunday. They were already open for 1.5 hours
2) What is outside source?
3) If all connections, fuses, alternator, and wiring check ok plus the store checked battery tender ok. Then why is battery not replaced?
4) When I tried to call store Sunday at noon no one answered. Called 4 times?
I was trying to get gentleman name for this complaint. I guess caller I'd someone decided not to answer. Just by chance had s friend pass by sore with no customers, guy behind counter just walki g around while the 4th no answer call was made.

In all Duracell warranty does not state warranty no good under 12 volts.
The battery no taken charge is a warranty issue. The outside source is a question to be defined. I did everything request of me y store with positive results except battery.
SOLUTION:
1) Replace battery
2) Explain outside source
3)Remediate customer relations

I didn't appreciate being lied to.
Call you after 48 hrs. BS
I tested then said he didn't. BS
Battery no warranty u der 12volts BS

Battery plus has enough complaints and doesn't need another one.

I rely on Battery plus to do right
