Red Flash - Technical

 

Features & Benefits of Red Flash sealed lead batteries:

Red Flash batteries use technology based on that developed for starting jet engines in military aircraft. They have been designed to provide very high current whilst maintaining a high stable voltage. The pure lead thin plate design differs from ordinary battery systems and gives a very much lower internal resistance, enhancing high current capability.

 

The advantage to you is a weight and size reduction of typically 50% together with the ability to withstand high shock and vibration. The long no load life is two years at 20 degrees c. There is no free acid in the batteries, they will not leak in case of damage.

A very high current (up to 1700A) permits fast engine cranking and easy starting even in very cold conditions. Red Flash batteries can be connected in series for 24V systems.

NB End of discharge voltage = 10V for a 12V system & 20V for a 24V system.

Red Flash Portable power packs

The Red Flash 8 can be used to start small engines. Weighing under 4 kilos, it is very portable. The Red Flash 30 is approximately 30 Kg. & will start larger engines. With a storage life of up to 2 years, it is ideal to carry as an emergency battery pack.

 

Charging Red Flash batteries

Charging from engine alternator or generator:

Red Flash batteries are compatible with alternator charging systems. The alternator is usually regulated at 14.4 volts. Voltage at the battery terminals during charging should be between 13.9 volts and 14.7 volts for a 12 volt system and 27.8 volts and 29.4 volts for a 24 volt system. No current limit is required as the batteries can accept all the current that is available.

Charging from a mains charger:

With the correct voltage regulation no current limit is necessary and therefore batteries can accept the full output of a large charger - 100 amps or more insuring fast recharge. It is beneficial for batteries to be left on charge from time to time for periods up to 24 hours to preserve the full capacity and extend the cycle life. Standard automotive chargers of 4-6 amps can be used but must be disconnected at the maximum time shown below.

* Red Flash 700/750 16 hours
* Red Flash 1100/1200 24 hours
* Red Flash 1800/3500 48 hours

Important: Do not boost charge Red Flash batteries under any circumstances. Minimum voltage at battery terminals must be 13.9 volts for a 12 volt system, and 27.8 volts for a 24 volt system, when the batteries are on charge. If the voltage is lower than this, the batteries will not recharge correctly.
