The Infinity X7 flashlight alkaline battery case is a quality product. I installed the batteries that came with the case and checked for proper operation in the flashlight. Every thing worked properly. The unit was well packed for protection and was received two days earlier than expected.

I have installed an aftermarket battery in my other Macbook a few years ago from another manufacturer and am very happy with it. I could not find a battery for my new laptop from the same manufacturer so I figured I would try this one. I am beyond disappointed. I should have returned it as soon as I opened the box. It looked like a very cheap attempt to duplicate what it should look like. There were zero instructions. I just youtubed them but the quality of the battery looked very poor. But I had it so I installed it.Right away the first 2 charge cycles it did not last any longer than my 5 year old OEM battery. After the computer relearned the new battery it seemed to be on track to be a good battery. But then while I was working on it and it was clearly around 25%, it completely died. Plugged it in and it was at 0%. Let it charge back up and it seemed to be fine again and lasting a long time, right up until it died in the mid 20% range again. That was all I needed. I looked further and was able to find a batt from the manufacturer that I have been happy with in the past and the first thing I did on the computer when I installed the second new battery was to process the return for this one, and then wrote this review.If it looks like a turd its probably going to be one, I should have known better, but I figured I'd try it. What I got for my trust was having to redo the job twice.No thanks, returning it. Do not buy this one. Plenty of other ones out there, and apparently they are NOT all the same.

Excellent product, but no instructions were included, and the replacement task is not trivial. Original battery is glued in, and getting it out is hard. I had to watch some YouTube videos (readily available) to see what to do. There are also a several cable removal and replacement steps. One cable in particular is tiny. You need good eyes, good light, and a steady hand to remove and re-insert it. There are neary invisible latches to flip....

Very well packaged and looked great! worked as described. Just make sure you have all of the tools needed to replace. You will need a scraper and another screw torx not included.

I am the most low-tech person of anyone I know, yet I was able to install this battery in my very old Macbook Pro on my own. I just followed the instructions in a couple of videos I watched and presto! It worked! The only snag is something that a few other people mentioned in their comments. The screw holes don't align correctly, so one of the screws had to go in at a slight angle. If there is any change in the way this battery works, I'll update my review, but for now, it's fantastic + I saved a lot of $ by doing it myself.

Decent quality battery set and good value. Easy enough to install if you know your way around Macbooks. If not consult Dr Youtube - slow and methodical wins the race every time especially when removing the old batteryUPDATE : battery was not holding a charge REMEDY reset your Macbooks smc - ref to youtube

So far so good. Aftermarket batteries can be a crap shoot. My last one ballooned up and cracked the track pad. This mostly likely was caused by leaving it plugged in, with these older machines and subpar batteries it’s best to leave them unplugged when not ised on the regular.
