Lead Acid Battery Long life question.

[ibrar0]

Hi,

I have a UPS, with AGS Battery of 160 Ampere, But use of UPS is very rare may be 5 minutes a Day, and battery remains always full all the time. My question is that, is it wise to discharge my battery once a month or week, will it have positive or negative effect on my battery life.
???
Thanks in advance.

If you deeply discharge a lead-acid battery then it is destroyed and might not hold a charge.
An ordinary car battery is designed to supply hundreds of Amps for only a few seconds to start the engine then immediately be recharged. It is destroyed by one deep discharge or its life will be very short.

If the battery is a "deep discharge" type for wheelchairs then it can survive a few deep discharges which will shorten its life, but it is destroyed if the discharge is too low.
