What means "battery with PCB"???
342992
A PCB is a circuit board built into the head of the battery that protects it from overcharging, overheating, short circuits, and also prevents the battery from being overdrained by your device (flashlight). A lithium ion battery can be ruined if it is charged over about 4.20 volts. Or if it is drained below about 2.75 volts. The PCB acts as a "circuit breaker" and shuts off any current from flowing into or out of the battery before it can be damaged. Even though they are more expensive, it's money well spent in the long run. A non protected battery can easily be run down below the point of no return. I hope this answered your question sufficiently.

I believe it's an abbreviation for replace. I purchased one of these batteries as a backup battery for my camera so I would have two. I am not 100% positive, but I hope this helps.

Don't remember. it is direct replacement for battery in security system. best price that i found.

You should have at least a basic charge controller to avoid over-charging your battery and possibly damaging it. The panel has built-in diodes to prevent discharging your battery when there's no light on the panel.

Some claim it's a cell phone battery you can find for $5 (with shipping, I doubt it.) Apparently, many defective radios and/or battery units were shipped. Nothing should be shipped to a customer where the customer is left trying to figure out how to fix it. I just sent the whole thing back and ordered a portable radio made by a different manufacturer.

I don't know what that means. Car battery? Don't think so. I have a F-150 work truck and leave it plugged in when I need it. Sometimes I forget it's plugged in, but hasn't ever killed my truck battery.

This is a battery maintainer, your batt. should be charged before you use this.

Since this is a lead/acid type battery, it is used in situations where it is periodically or continually recharged. Examples of a lead/acid battery are a typical car battery or a battery in an alarm system. In these examples the car charges the battery while the engine is running, and the alarm system charges the battery continuously as long as the house power is available.

Battery? What battery? Mine is powered by DC but there is no battery. Just the 12v wiring in my motor home, like in an automobile.

All I know is that I ordered battery, charged it completely and it works great in my combo kit(drill, circular saw, reciprocating saw). NO problems whatsoever! Hope this helps!

I think the bp stands for battery pack. And I'm pretty sure it's the same whether it has a bp or not. Hope that helps...

To tell the truththereis noway to open it so i guessit means batteries that u dont replace. Has certian amount of hrs then the unit is dispoasable. But thats just my guess since its nano wide so it would b invisable battery ad no place to openunit. Just so many thoudand hrs of use and over

its not a battery. its a capacitor (large value one). it takes a while to charge up (assume something like an hour or so, not a few minutes) and only holds power for short periods of time, such as a brownout or power failure. its NOT a battery, it cannot be replaced and would be dangerous to replace it.also note this circuit is not meant for 5v use. those using it on arduino should power the top lead (vcc) from 3.3v and not 5v! the i2c inputs are 5v tolerant.

I'm pretty sure it's a small NiCad battery, the type used on OLD computer motherboards to keep time/date info while the computer was off. I have no idea why this was included with the light.

It appears that it is "not" a Chamberlain battery. It says VB Rechargable on the side. I must say that it works ok.

Yes, it's to keep the battery from running down while in storage/shipping. Like many electronics that come with battery included.

Don't know what the technical term is for this battery, all I know is it is a lot better than the battery I received with my computer when I purchased new. Paid about the third of the price.
