Tj Technolo Laptop Battery Tips
How to connect a battery in Series?
The positive terminal of the first battery is connected to the negative terminal of the second battery, the positive terminal of the second is connected to the negative of the third, etc. The voltage of the assembled battery is the sum of the battery voltages of the individual batteries. So the batteries are connected: + to - to + to - to + to -, etc. The capacity of the battery is unchanged.
What is the marine cranking rating (MCA)?
The marine cranking ampere (MCA) rating refers to the number of amperes a battery can support for 30 seconds at a temperature of 32°F until the battery voltage drops to 1.20 volts per cell, or 7.20 volts for a 12V battery. Thus, a 12V battery that carries a MCA rating of 600 CCA tells us that the battery will provide 600 amperes for 30 seconds at 32°F before the voltage falls to 7.20V. Note that the MCA is sometimes referred to as the cranking amperes or CA.
Does my deep cycle battery develop a memory?
Lead acid batteries do not develop any type of memory.
What is the difference between a Ni-Cd and Ni-MH chemistry battery?
The main difference between the two is the fact that Ni-MH batteries (the newer of the two technologies) offer higher energy densities than Ni-Cd's. In other words, pound for pound, Ni-MH delivers approximately twice the capacity of its Ni-Cd counterpart. What this translates into is increased run-time from the battery with no additional bulk to weigh down your portable device. Ni-MH also offers another major advantage: Ni-Cd batteries tend to suffer from what is called the "memory effect". Ni-MH batteries are less prone to develop this dreaded affliction and thus require less maintenance and care. Ni-MH batteries are also more environmentally friendly than their Ni-Cd counterparts since they do not contain heavy metals (which present serious landfill problems).
