Non-lenovo batteries

Can anyone attest to the quality of batteries by after market manufactures like BTI or OnCore Power? They claim they are drop in replacements for batteries from Lenovo and in some cases can be up to 50% cheaper.

Can you really tell if you have one of these batteries in your computer? Does it look different? Behave differently?

Thanks in advance!

 

With name brand batteries tending to burst into flame these days, do you really want to touch a knockoff?

 

How about ultrabay batteries? Aren't those made from Lithium Polymer?

But it does seem like knockoff batteries are risky.

 

If you are still under warranty I recommend atleast keeping your dead battery incase you need to send your notebook in to be fixed. A lot of companies will not fix a laptop that has a battery other than OEM.

 

Stick with originals mate.

 

Have you thought about getting your battery rebuilt?

 

Lenovo batteries do have some safety circuitry designed to disable the battery if an unsafe state is detected.

Even though it costs more, I would only use the manufacturer's batteries.

I used to use 3rd party batteries in my cell phone, but dropped that idea. I also don't leave any rechargable batteries plugged in unless I am present in the house.

 

All li-ion batteries have that circuitry. It prevents them from charging or discharging too quickly. They were made manditory after the early li-ion cell phones vented off in people's ears.

I think people are way too worked up about a few li-ion batteries cooking off. It's actually not that easy to cook off a li-ion battery. I take apart old laptop batteries to use for robot projects. Which is way beyond what they are intended for. I haven't cooked off any yet. I did cook off a NiMH once. Wow. It was a mini geyser.

 

Words to live by.
