Replacement battery for the BPS-F digital scale for DIY replacement.
Technical specifications:
Absorbent Glass Mat (AGM) battery / Sealed Lead-acid battery
Voltage: 4V
Capacity: 4.5 Ah
Dimensions: 48 * 48 * 100 mm
Contacts: 4.7mm male spade terminals
Important note: This rechargeable battery is ONLY suitable for the BPS scale.
All other G&G scales equipped with a built-in battery require the 6V battery, which you can also find in our shop.
Installation note:
Depending on the scale version (the BPS has been on the market for >10 years and has undergone minor design revisions), 2-3 wires are soldered to the battery terminals, which may differ in insulation color.
We recommend taking a photo of the original positioning and the wires connected to the terminals before removing the old battery. This ensures you can correctly reconnect the wires to the battery terminals (marked Red + and Black -).
Replacing the battery requires EITHER a soldering iron and solder OR 2 fully insulated female spade connectors (width: 4.75 mm, insulated. Sample product) along with a suitable crimping tool.
Operating temperature:
The optimal operating temperature is 20°C. In winter or cold storage rooms, the performance of the AGM battery is restricted, as a cold or frozen battery delivers less voltage and accepts less charge.
Lifespan:
6 months to 8 years, depending on usage. The service life of a lead-gel / AGM / absorbent glass mat battery primarily depends on the number of deep discharges and how long the battery remains in a deep-discharged state.
If the battery is consistently used until the scale shuts down due to insufficient voltage (after 20 to 100 operating hours, depending on the model and settings such as backlighting), it will have a shorter overall lifespan compared to a scale that is regularly fully recharged after a few hours of operation.
Permanent deep discharge is the most harmful state for the battery: storing a scale with an empty battery and leaving it unused for several months.
We recommend fully charging the battery before storage and recharging it at least every 6 months to prevent damage from natural self-discharge (the battery loses approx. 2% capacity per month).
If the scale is only used once a year (particularly seasonal use like harvest time each summer) without intermediate charging or storing it fully charged, the scale will fail to turn on after just one year because the battery has been permanently damaged by deep discharge.
Technical background regarding service life:
The lower the voltage inside the battery, the faster chemical processes cause deposits to build up on the terminals (sulfation). The affected areas can no longer store energy, reducing the battery's capacity and accelerating future degradation. Over time, these deposits grow so large that the battery can no longer deliver the minimum operating voltage required by the scale. As a result, the scale will not turn on, even when connected to the power grid/mains supply.
