Battery tester that makes a mark
It needs to be understood that the BT3554 comes standard with a pin-type lead, however this design turns out to be difficult to use in certain applications as it may not fit between equipment racks in a proper manner. This is why Hioki released the Pin Type Lead L2020 as it has L-shaped tip alongside the BT3554. It is the best brand battery tester that you get to find so check it out and make a decision.
You can even check and compare various types and models of battery available in the market and then go on to make a decision in this regard.
