Should I wait for my notebook battery to get completely dead

Specs: Windows
I took my HP notebook to a service center and the engineer said I need to replace my battery.

My battery gets charged only till 80% (not more). When running the laptop on battery power, it turns off when the charge comes down to 55%. So my battery works for 30 minutes approx.

Should I keep using my current battery until it is completely dead or replace it immediately?

Is it safe to keep using it?

Thanks

Wait for riider and one or two others here who are well up battery technolgoy - before going along with the local techie's advice.

Incidentally how olde is the laptop and what is the actual model?

I would suggest always use the battery till 10% left and charge the battery till 90% and then unplug, This will help you in be away from overcharge, and also helps you reduce the charge cycles and increase the battery life.

Whether you replace the battery now or later at least start looking for one now. It's probably a good idea to avoid no-name replacement batteries from China. Look for an HP or OEM replacement.

When it become impractical to continue using the battery because it does not have any real life left in it, then it is time to replace it.
If you know someone who has a similar HP laptop see if you can borrow their power block (AC power adapter/charger) and see if your battery charges batter. If it does then maybe your 'charger' is not putting out the correct voltage any longer to charge it properly. If it suddenly charges to 100% and lasts longer then replace the power block instead and the improved charging may improve even more over the next couple of charges.
I also recommend being careful with 'other' brands on batteries. If the battery cells are poorer quality, the cells are not matched to each other (capacity, internal resistance, rate of charge, etc), or is made with inferior components (connecting bars and wire - material and thickness) then the pack will not last. HP original battery packs will be pricey but if you are careful then you may find someone who makes or purchases from the maker of some of HP's actual battery packs and get them at a nice savings.

You have to be a little bit crazy to keep you from going insane.

Hi, AKS still has not advised the full Model Number or how old the Battery is.

I disagree with the above regarding OEM Batteries.

For various Laptops, belonging to me and others, I have always purchased OEM batteries and saved much. Invariably they are made in China.

I research carefully, do not buy the cheapest, look for a higher output than the original if available, and the same number of Cells. Invariably they come with a two year guarantee.

None have failed so far, and if one did towards the end of the Guarantee, doubt I would claim as cost per month works out so low.

Good Luck - Keep us posted.

I’ve found that the big forest company (it’s namesake currently burning furiously...) often has decent and reliable batteries, and mains adapters too. And useful reviews too.

Egghead is often a reliable source too.

True many/most of the batteries are made in China but quality varies. Name brand and OEM are expected to be as good as what the laptop originally came with. Others. . . well not so much.

If you replace it sooner, you will have a better battery for backup purposes. That is if you intend to continue to use your laptop for a long time still ..

I would look around on the second hand market, you may find almost free used batteries of the same type, which on itself may not be perfect, but some will be better than the one you currently have.
