Which Fluke Instruments Use the BP500?
The BP500 is supplied as the standard battery with all three Fluke 500 Series Battery analysers: the entry-level BT510, the mid-range BT520, and the advanced BT521. These handheld analysers are used by telecom, data centre, utility, and UPS maintenance teams to test the health of stationary lead-acid and VRLA battery banks in the field, so a dependable spare or replacement pack keeps test schedules on track.
When to Replace Your Fluke BP500
- Your analyser runtime has noticeably shortened between charges
- The pack no longer holds a charge overnight
- You are equipping a second analyser or building a spares kit for field crews
- The original pack shows physical swelling, cracking, or connector wear
