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.

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.

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.

Short battery life.
Bought 2 batteries on October 2025 and by January 2026 one has already gone bad not the best product. Going bad in 4 months.

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
