Ans. Battery has a cycle life, so it all depends on how many cycles we use in a day and that is what decides the battery life.

Ans. Each battery has a flat warranty as well as Prorata warranty. So customer should refer to warranty policies before buying a battery.

Ans. Replacement process depends upon warranty policy. There are two types of Warranties:
 A)  Flat Warranty – In it, Customer will get replacement in the mentioned period.

Ans. If company is giving onsite warranty, then you should report to company. Else you should contact the dealer.

Ans. GEM batteries has come up with new technology i.e. HCCA technology for Automotive batteries which ensures that our batteries are designed for harsh terrain and extreme conditions and ELDC Technology for inverter battery which makes sure that your battery perfomrs in worst power conditions . ( for more information on these technologies, kindly visit our website www.gembatteries.com)

Ans. It depend upon the consumption of home. 400 VA 88 – 135 AH 600VA 150 – 180 AH 800 VA 150 – 200 AH 1400 VA 150AH X 2 BATTERIES

Ans. Yes, you can run your Computer on battery but it depends on 
    a) How many other appliances are also running at the same time.
    b) Also on inverter size , preferably it should be a sine wave inverter

Ans. GEM Batteries are low maintenance; lead acid batteries. So nature of this battery is said to be flooded battery.

Ans. Number of batteries required for inverter depends on Inverter, circuit voltage e.g.

Circuit voltage battery required
12V 1
24V 2
36V 3
48V 4

Ans. Ideally the invertor battery should be installed where air circulate.

Ans. Battery is being used with your inverter, both should be placed together and treat them as your TV and the way you wont put your TV under the open sky, don't put them either. So it is always advised to keep them at the comfortable place, so that they can be maintained properly and easily
