Works like OEM battery.
Equal to OEM battery. You can order without hesitation. As it states on the packaging, charge completely before you use it. I'd purchase again.

Upgraded Intel Battery at a reasonable-ish price
I got this replacement battery for MAGLITE ML150LR. The original INTEL battery one day refused to accept a charge… Me and a bunch of coworkers got the same light as a present and they one by one stopped charging. That’s no problem surely the battery can be replaced- A replacement Intel battery was about $50!! Woah!! This is a flashlight not a piece of machinery… So when I saw this upgraded battery with increased capacity for half the price I was intrigued. It is the same size and function as the original battery it installed in seconds easily. The light finally works again! It seems much brighter but can’t compare as original battery was toast. I think this was a good value replacement battery. I will update this review on durability if it fails but for now it is working and charging as expected and I’m pleased with my purchase.

Work well
It’s the exact same battery maglite sells for $40 on their website. Works 100%. They don’t seem to last long though because this is my 3rd one

Did not take as many recharges
This is the compact mag light. I use it for approximately three hours every day. It doesn’t seem to take as many recharges as the original rechargeable mag light but still good.

Exact fit to replace a dead battery.
Fits perfectly in my Maglite ml150lr flashlight. My battery won't charge even after waking it up so I ordered this one. So far it holds a charge and recharges. This makes my expensive flashlight usable again. Works as it should.

Cumplen el objetivo
Son baterías que cumplen con el objetivo de reemplazo de una batería OEM de Mag lite, sin embargo su periodo de vida disminuye y a larga los tiempo de carga en poco tiempo. Considero que para uso residencial que es el uso que les doy yo es buena, mas sin embargo no para un uso de caseta de vigilancia no, ya que al ser mas constante la pila se va deteriorando en corto tiempo. he notado que a carga full la intensidad de la luz ha disminuido a poco tiempo y la duración también.
