3.7V 3600mAh ICR18650 Rechargeable Battery Pack with SM 2P Plug

I worked fine on a bovovr batterie pack after cutting off connector and welding onto pack circuit board. whey cheaper than a new batterie pack.

I've seen many people give this a low rating because they couldn't just plug it into the same place where their old battery was. This isn't how rechargeable batteries work. The days when you could walk into Radio Shack with a cordless phone battery and get an exact replacement are gone. Consumers are basically responsible for changing the plug out themselves if the battery doesn't come with what you need. This is not a difficult task if you have decent eyesight and a steady hand. If you lack these, then ask a family member to make the change for you.That being said, the battery is exactly what I needed - 3.7v, lithium-ion, and a generous 3600mAh capacity. The fact that it already has a pigtail attached - whether the plug is exactly the same or not - means I don't have to solder anything to it myself. In my case, the plug fit. But if it didn't, I would simply splice the old plug onto the wires on the new battery, or take the pins out of the plug and insert them into the old plug.Overall, it's an excellent battery that does what it's supposed to do.

Item was fine…received in a timely manner…but had to return because the plug did not fit the receptacle…no problems with return…had refund added back to credit card within 4 hours of dropping item off at UPS store.

Needed a battery so ordered it to replace a low rechargeable in my doorbell video camera. Not as good as I would like for it to be but at least it works. Have to charge it very often. But it makes the camera work.

I ordered the battery as a replacement for a device I had, hoping it would fit better. Looks like it is an exact fit as the original battery was taped in and loose in the holder. So way better battery.

Battery never held charge more than 2 weeks w little use. I sent it back at my expense. They replaced with another defective battery. I complained. Send it back, thy said. Me: how about you pay shippng this time? Them: This could go on forever, we'll prorate refund (~50%). Me: won't go on forever if you send a non-defective battery. They refunded. The end.

Installed as a replacement in outdoor solar LED setup. Original battery was about 5 years old and would only hold charge for a couple hours, not all night as when new.This replacement battery worked fine for about 6 months, then it would not charge at all. Vendor replaced the battery but I had to pay the return shipping and was without my lights for a couple weeks. Hoping the replacement is better quality.

Works great in my outside motion sensor lights for my chicken coop. Should last longer that the original 1800mah battery. Also much cheaper than replacing the whole light.
