User Reviews about IBM Lenovo R61 R400 41U3198 Series Battery

Worked great for 6 and a half months, but then just completely malfunctioned. Not heavy use or heavy charging. Did not die gradually, but malfunctioned with no prior signs of a problem.

For 6 months it was equivalent to the factory original battery. However, my factory battery lasted for over a year and died out somewhat gradually after that point. Having successively smaller charge capacity. This battery only lasted for 6 months and had an abrupt critical malfunction.

If you need a battery to tide you over till the end of a school semester, or just to help you bridge the gap to your next computer, then this is a decent buy. However don't expect the same longevity you received from your factory original battery.

At the current price I don't believe that it's a bad purchase, even considering the relatively short lifespan of the product. -- Lasted over 6 months, but then had abrupt critical malfunction.

When you're stuck with a proprietary battery, they can end up being so expensive that a new laptop starts to seem like a reasonable expenditure. In this case, though, the 3rd party solution has worked great, and I'm back to watching movies in bed without needing to drag out the power cord. -- Fits my laptop perfectly, works quite well

Shopped around for a replacement battery for my Lenovo laptop. Very pricey, about $150. This one at $39.99 semed to good to be true but I couldn't pass up on that price. At first it would not charge and I thought I got what I paid for. But with a little care in putting it in the laptop the connection was made and working like a charm.

This is a very good deal in price and delivery. -- replacement battery
