This kind of battery is capable of many thousands of charges as long as the draw is small. The further you discharge the battery, the fewer charges it will be capable of throughout its life. So charge it as often as you can, and you will help extend its life greatly.
It will be delivered to you almost fully charged if it's going into something with its own always-connected mains charging circuit. Maybe something like an alarm monitoring system, then it will look after the charging of it for you. It will almost certainly do a far better job of it automatically than you could. It would not be unusual for a battery to last upwards of ten years in such an installation.
If, however, it's going into a device that requires you to plug it in manually to charge the cells, then its life span will be drastically reduced. So it is important to try to keep the battery charged. Charge when it arrives and before first use; recharge immediately after every use. Please do not go out of your way to run it down or discharge it. This will only shorten the expected life span. The other thing to remember is if you are not using the battery pack for long periods, make sure you recharge it every five or six weeks to maintain a positive charge and never leave it on the charger for more than 24 hours.
This battery type is recyclable; its main content is lead, so ensure you give it to the appropriate body to enable it to be recycled in full.

As stated above, this battery can be seen in many devices; the primary battery will be as the picture; some device manufacturers may fit parts to it so it fits in their equipment. Maybe a top cover will change how the terminals sit. You will almost certainly not be able to get a battery with that cover on unless you contact the maker of the device. As there are so many different kinds, often in far-flung places, you will struggle. If you have a battery with 3fm4, 3fm4.5 or 3fm5 written on the side and appears to have a different top, look closely at it. It's probably been glued on, and the regular terminals are underneath. You have nothing to lose by gently easing it off and seeing the proper terminals underneath. Then, it's just a matter of swapping the battery over. Generally, the alternative is throwing the device away as it's doubtful it will get a battery with that bespoke piece that the toy or torch manufacturer stuck on in the factory.
