These tests below only note my personal opinion for the ESTIMATED ratings for the batteries I tested at the time I tested them. Any battery that is not a genuine Samsung, Sony, Murata, LG, Panasonic, Molicel, EVE, Lishen, BAK, or Sanyo can change at any time! This can be one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.
Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of property damage, personal injury, or even death. Never use them outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous discharge rating (CDR), never let it get colder than 0°C or hotter than 60°C to help lower the risks and extend cell life, and keep the plastic wrap and top insulating ring in perfect condition. Never use a battery that is physically damaged in any way.
Testing batteries at their limits is dangerous and should never be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.
If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.
Test Results
This is a great performer at moderate to high power levels and is only beaten by a small number of cells. At very low or very high power levels there are better choices though.
The 45T uses the new model numbering by Samsung along with a revision code, CC4503F101 Ver C for the ones I tested. The short version model number, 45T, is still on the metal can though and can be seen through the wrap near the top using a bright light.
I only have the RUMORED specs from a faked (lots of spelling errors) Samsung spec sheet for now…USE THESE RATINGS AT YOUR OWN RISK:

- Standard capacity = 4500mAh typical/4400minimum.
- Standard charge rate is 2.25A, max is 6A but I am sure that will shorten cycle life.
- The “max continuous discharge” rating is 35A with a temperature-limited non-continuous rating of 50A if you never let the cell get hotter than 80°C.
- In my testing though, like all Samsung’s, the 45T ran a little hot for its rating so I am estimating its continuous current rating to be 30A.
- If you run it in bursts at up to 50A be sure to never let the cell reach 80°C! To keep the cell from aging quickly I recommend staying under 60°C max.
- At 5A the 50S, P50B, JP40 are a bit better with the P45B are about the same.
- At 20A theP50B and JP40 are a bit better and the P45B and 40PL are about the same
