Hello Hanees,
Tungstone would not have been the original battery, but it has been - still is? a bought out brand name from 2009. Having said that it appears ‘the company’ was dissolved in 2019, so your battery could be at least 5 years old, and if so is probably passed its prime.
Of course Hanees, I cannot claim your symptoms are totally due to an ailing battery, but it wouldn’t surprise me if they were.
If you do decide to renew it, I’ve bought Exide Premium from Tayna Batteries ( no connection with the company) to good avail in recent times. There are others inc. Battery Megatore, but if you do decide to buy one, it’s worth investing a bit extra in quality. I never buy batteries on price, but by quality - min. 4 year warranty ones at best price.
Kind regards,
Gareth.
