NinjaBatt 807956-001 HP Battery for HS04 HS03 807957-001 807611-421 HSTNN-LB6U Notebook 15-AY039WM TPN-I119 G4/G5 240 245 246 250 256 - High Performance

Perfect, fits my laptop perfectly, came pre charged, and it works!! My other battery didn’t work but this one fixed my issue! I used a 15-f211wm hp laptop

Got this battery to replace my original battery that is 12 years old. So far so good. I guess I'll see how long it lasts. Fit was fine and it came about 75% charged.

There was some issues with shipping by Amazon said it was going to take almost 2 weeks but it came in less than a week, so I popped it in and didn't get any power and I thought it was going to be like buying the cheap junk batteries, I left battery in the Hp 15-Bs234wm laptop and it drained it down so I charged it and found out that there was No Driver for Charging system, I put a clock on it and after 4 hours of reading I turned it off and checked it the next day and at 20% I charged it again as the instruction say, I did the next charge watching YouTube videos for 31/2 hours and it was at 35% still so read the News paper and finally charged it again and I haven't turned it on yet since I'm going to install some software I bought for OBD2 and I'll see how it does with diagnostics on the Ford but for the price it's fantastic value compared to the off Brand Hattie's I've bought also I'm going to see if they have one for My old tank of a Dell laptop 1501 Inspiron hopefully they have one cause I have gotten a descent battery for my Dell every best has been an hour,, so these Ninja batteries are worth the money so far hope that they stand up over time!

Fits perfect. Works fine. Only have about an hour worth of time after a full charge. I need to find one with more capacity

The battery worked right out of the box. It's brought new life to an old laptop that I thought we'd never use again. The charge is long lasting and allows for a lot of work to be done while not plugged in.

I have to say I was expecting a weak battery that would not keep a charge. I was pleasantly surprised. Delivered at 1/2 charge, popped right in and started working immediately.

Best Buy's geek squad told me my laptop was basically no good and to purchase one at their store because finding a battery would be difficult and very expensive, well they were wrong, my laptop now holds a long battery charge and I am happy with my purchase.

It's a battery. Snapped it in, fits like a glove.Turn the computer on. Plugged the charger in. Works like a champ.If my computer last another 4 years. I would buy it again.Thanks!
