Laptop Battery Problems!

LOL. The laptop is getting worse. I'm having anywhere between 50% of charge on good days lasting for just over an hour to 25% lasting 20 minutes on bad days. I'm trying not to charge the battery more than twice/thrice every other day. My Tablet has been brought out of storage to take the brunt of all my online work.. .

I'm hunting around town for a genuine battery replacement for my laptop. It's hard since HP doesn't offer any hardware/software assistance anymore for my laptop, that period has passed. I hope to get a replacement battery by the end of next week. I need this laptop to last another 1.5 years at the very least. I can get myself a new one then hopefully. .

Thanks for the advice everyone.
