Cheap poor quality batteries do not hold a charge for a long time. Measure the voltage in 2 months and if the voltage did not drop then measure the voltage each year.

please what links, many opinions is good
No, many opinions, and many topic posts that waste everyone's time are NOT good.

If you refuse to follow advice and info already received, it must be because you know more than everyone else because you exercised due diligence to research and educate yourself from a battery authority such as a major battery manufacturer, not just accumulating as many opinions as possible. Science is not like voting for a president where the most popular option wins.

Besides, if you have not already sealed your batteries in concrete in a drum and buried them in the ocean, then you are not following suggestions so it is very rude to ask for suggestions again.
