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

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

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.

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.

Met Expectations

I bought 6 batteries. All dead on arrival.zero charge

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.

Finally cleaned up the dive gear for inspection and was surprised to find 10 year old battery(s) in two dive computers that never leaked.

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!
