The luminous brand is very popular in Nigeria when it comes to inverters and batteries. Luminous batteries are manufactured in India. This Luminous SMF 220AH inverter battery is designed to be used for inverter and solar installations as you will expect. It is called SMF(Seal Maintenance Free) because this type of battery requires no maintenance at all; unlike wet cell batteries. This is a 12V 220AH battery, meaning if you use a 12V inverter, you can use basically either 1 or 2 of these, a 24V will require the batteries in pairs(2, 4 or 6).
These Luminous SMF inverter batteries are usually more designed for ease of use; they provide the option of installation ina relatively smaller space. Also, they are considered dry because there is no electrolyte that can spill. A single battery of this type is capable of providing back-up power to a relatively small apartment with one TV and two fans; backup time should be a minimum of 6 hours depending on inverter efficiency. You can get longer backup time by using more batteries as long as your inverter can safely charge them all.
Sealed inverter batteries usually carry a warranty period of about 6 to 12 months. They are the goto battery to get for inverter installations.
