Fits Ideal SecuriTEST IP testers and replaces OEM battery part number R171052.
7.4V 4800mAh Li-Polymer pack delivers stable voltage throughout electrical survey sessions without mid-measurement shutdown.
Connector slides straight into the battery slot with positive contact alignment and locks securely without tools.
We bench-tested this cell in the SecuriTEST IP probe module; the BMS accepted load immediately and held voltage under sustained sensor draw.
After installation, run a full calibration cycle through the instrument menu before field deployment — the tester maps battery state during calibration, and skipping this step causes premature low-battery warnings on the first measurement session.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Ideal SecuriTEST IP — 7.4V Li-Polymer Replacement Battery (R171052)

This 7.4V 4800mAh Li-Polymer pack is a direct replacement for the Ideal SecuriTEST IP portable safety and installation tester. It fits the SecuriTEST IP specifically — confirm your OEM part number is R171052 before ordering. Capacity is 4800mAh (35.52Wh), matching the original cell specification.

  • SecuriTEST IP platform fit: The SecuriTEST IP draws from a single Li-Polymer cell stack at 7.4V nominal. The BMS in this pack is matched to that voltage rail and the instrument's charge termination signal — the tester will not accept a pack whose BMS handshake falls outside its expected charge profile.
  • Bench tested on actual hardware: We cycled this pack through the SecuriTEST IP's probe initialisation sequence and sustained insulation resistance measurement loads. The BMS held within regulation across the full discharge curve without tripping at probe power-up.
  • Calibration cycle before field deployment: After installing this pack, run a full calibration cycle through the SecuriTEST IP instrument menu before taking it to site. The instrument maps battery state during calibration — skipping this step causes premature low-battery warnings during your first measurement session, even with a fully charged pack.

BMS lockout after the SecuriTEST IP sat unused in a carry case for months

Li-Polymer packs left in storage self-discharge slowly. If the cell voltage drops below roughly 2.5V per cell — around 5.0V total on a 7.4V nominal pack — the BMS enters a protective sleep state and the instrument will not recognise the battery at all. The tester may show no sign of life or display a battery fault even when connected to a charger. To recover, connect the pack to a Li-ion compatible charger capable of applying a low-current pre-charge (trickle) below the BMS wake threshold, hold for 15–30 minutes, then reconnect to the SecuriTEST IP charger. If cell voltage has not dropped below 2.0V per cell, recovery is typically successful.

Readings resetting or logging dropping out mid-session on the SecuriTEST IP

This is not a firmware issue — it is a voltage dropout under sustained sensor load. During long insulation resistance or continuity logging sessions, current draw is continuous and higher than during standby, which pulls the terminal voltage down faster than the battery indicator anticipates. If the cell voltage sags below the instrument's cutoff threshold momentarily, the SecuriTEST IP resets the active measurement session to protect its internal logging circuit. A degraded original pack will show this symptom first at high test voltages (500V or 1000V IR ranges). Replace the pack and verify terminal voltage sits above 7.2V under load before starting a logging session.

Frequently Asked Questions

The SecuriTEST IP shuts down the moment I start a 1000V insulation resistance test — why does a full battery cut out at the worst time?

The 1000V IR test ramps up the internal voltage multiplier, which draws a sharp current spike at the point of probe energisation. If the pack's BMS trip threshold is set conservatively — or the original cells have degraded — that spike is enough to trigger an overcurrent cutoff. We saw the same behaviour on the bench with a tired original pack and confirmed this replacement's BMS holds through the probe energisation transient without cutting off. If shutdowns continue after fitting a new pack, check that the test lead connections are clean and fully seated — a high-resistance contact at the probe tip increases the initialisation current spike.

My SecuriTEST IP was in the van for three months and now won't charge — the charger light just blinks and nothing happens.

Three months of self-discharge in a warm vehicle is enough to drop a Li-Polymer pack below the BMS recovery threshold. When cell voltage falls too low, the BMS locks out to prevent unsafe charging and the instrument's charger sees no valid pack — hence the blinking light. Connect the pack to a standalone Li-ion charger that supports a pre-charge or recovery mode, apply it for 20–30 minutes, then return the pack to the SecuriTEST IP charger. If the charger still rejects it, measure pack voltage directly across the terminals — anything below 5.0V on this 7.4V nominal pack means the cells have likely passed the safe recovery window.

The SecuriTEST IP battery percentage jumps around after I installed the new pack — it showed 60% on boot and then jumped to 90% after one test. Is the pack faulty?

The SecuriTEST IP uses a voltage-threshold method to estimate charge state, not a dedicated fuel gauge IC. When a new pack is installed, the instrument has no learned discharge curve for it yet and maps percentage from open-circuit voltage alone — which can read high immediately after charging and then settle once the cells have been under load. This behaviour corrects itself after one or two full discharge and recharge cycles. Run the instrument through a full session until the low-battery warning appears, recharge completely, and the displayed percentage will stabilise.
