TL-2150/S 3.6V 1/2 AA 1 Ah Lithium Battery (ER14250)

I'm supposed to rate the features such as longevity (obviously a forced, unknown value) along with Battery life (same thing, maybe?) and again unknown. This is an exact replacement for the backup batter I needed for a datalogger and approximately 1/2 the price of one locally. It got here quickly and I was happy to find it was indeed a brand name, exact match for the one I took out. I am pleased (except for the evaluation form which is goofy.

Perfect for my pulse oxygen digital. Didn’t think I’d ever find such an odd size battery.

Didnt work for what I needed. My fault

Met Expectations

It is used to power my dive computer. It does what it’s supposed to do.

Battery arrived expired (June 2020). Company tried to say insert it correctly…or be sure it’s the correct size for your device. I’m 100% sure-I have the owners manual foe the device. Also it’s inserted correctly-but it’s expired over a year and doesn’t have enough power to power on the device! They refuse to allow me to return it. Never buy from them!

Summer of 2020 during Covid lockdowns, I decided to replace the battery in my old snowball Mac. Backup battery died years ago. So far this battery is doing well. I would expect to get at least 4+ years out of it.

I was hoping this would simply solve the startup of an old G5 Mac but it didn’t. I assume the battery was fine. Note: Not sure why longevity and battery are rated upon purchase rather waiting some time to see how it does over time.

Exactly what I ordered, delivered much faster than I expected. Super service.

To replace the same old battery used in a light switch, hope it's less expensive or rechargeable.

It lasted for a couple of mins.

Works as promissed

Battery arrived quickly but like a lot of these, it was dead and did not work. Sent it back for a refund and ordered a new one from a different vendor. This one came fully charged as it should.
