I have currently installed 50 AH Phoenix (Battery model is perhaps CNG 65 and having 11 plates per Cell if i remember correctly)
I am much satisfied with the performance. Nowadays, lot of price variation from dealer to dealer but available around 7,000. Some are selling it near 10K too.
You can also experience 45 AH Daewoo Maintenance free battery which will cost around 11 K+ but worth it.
But opting from both, also check your current battery base plate as well as terminal thickness as Height of 50 Ampere Phoenix is smaller than 45 ampere Daewoo battery but length and width are more than Daewoo.
Secondly, it is nowadays almost must in Pakistan to install battery theft lock/cage to save your Battery
