About laptop batteries and laptop chargers

Did you know that one of the most important and complicated decisions you can make in http://www.laptop-battery.org.uk is choosing the correct battery charging system for your boat? Charging your laptop batteries is a simple process of driving electrical currents into your battery in the reverse direction as the discharge occurred. Although rechargable battery packs can be a simple process, many things do factor into your decision and play a roll in choosing the proper charger.
The goal of our experts is to help you make an informed decision when you replace or add an on-board charging system to your vessel. You are adding value to your boat by having an on-board battery charger. In addition, these chargers also offer you the convenience and the ability to charge multiple batteries at the same time. You no longer will need to drag out a portable battery charger every time your Lithium-ion battery need to be charging. Maintaining your MSI laptop battery will be as easy as plugging in your boat to any 110 volt outlet.
The first step in the process is to identify what type of batteries you have on board your watercraft. You will need to look for some specifics about the batteries you are wishing to incorporate into the charging system. You will need to determine the following:
- Voltage
- Battery type
- Amp-hour capacity
Typically, in the marine world, you will be dealing with 12-volt systems. The battery's capacity is usually listed on the battery as "ah" or amp hour. Marine batteries will be one of the following types:
- Flooded/wet cell lead acid
- Starved electrolyte AMG
- Maintenance free

MSI  laptop Chargers typically come in single, double, triple and quadruple bank systems and should have independent outputs to charge each battery separately. The battery industry recommends charging your battery at approximately 15-20 percent of its capacity. For example, a 100-amp hour battery would be best charged at 15-20 amps. For your safety, be sure the battery charger you buy is UL listed to Marine 1236 standards and FCC compliant. If you choose a charger that is too large or small for your batteries it could damage them and decrease the life by overheating, gassing and causing excessive water loss.
Depending on what type of boating you enjoy, you will need to make sure your on-board charger's waterproof housing is designed for fresh and/or salt water. It is also important that you make sure it is vibration resistant and incorporates built-in reverse polarity protection. To prevent boil over or your battery over-heating, be sure the charger you purchase has an automatic temperature compensation, this feature adjust output depending on the temperature to assure a fast full charge in any weather conditions. We suggest getting a charger that will charge in three stages typically these stages are:
- Bulk or quick charge mode - gets your batteries charged quickly
- Absorption stage - brings your batteries to a full charge
- Maintenance or trickle charge - keeps your batteries charged and protects batteries
