The Bright Way Group BW 12500 NB is a 12-volt 50Ah sealed lead-acid battery that is brand new and ready to replace your existing battery (regardless of the original manufacturer).

This is a 12-volt (12v) battery. You should ensure that your current battery is a 12v battery. You can combine multiple 12v batteries in series if your equipment needs a higher voltage. (Reference your product's manual for further details.)

The capacity of the battery is measured in amp hours (Ah), and this is a 50Ah battery.

The model number of this battery is BW 12500 NB. Sealed lead-acid batteries (SLA) come in two variants: either gel or absorbent glass mat — this indicates the material inside the battery itself. This battery is the AGM variant.

This battery has an NB terminal, sometimes referred to as a Z terminal. You may see this same battery labeled as BW 12500 Z. (Other terminal options may be available. See the difference between terminals.)

All SLA batteries are maintenance-free, can be used in any orientation, and are leakproof. They are exceedingly safe because they use a valve regulator to safely vent pressure. (You may see SLA batteries also referred to VRLA, valve-regulated lead-acid.) In addition, these batteries have a wide operating temperature, a long service life, and the ability to recover from a deep discharge.
