FAQs

Electronic conductance testers are the modern workshop standard — non-invasive, fast (typically 5-15 seconds per test), test discharged batteries safely, and give a clear CCA-equivalent reading. Used in fleet workshops, recovery operations, and battery-shop service. Load testers apply high current and stress the battery — useful for confirming a high-end battery's true performance under load, but not suited to weak or discharged units. For day-to-day workshop battery testing, an electronic conductance tester is the better choice.

Modern conductance testers accept the battery type as a setting before the test — they apply different test profiles for standard wet-cell, AGM, gel, and EFB chemistries to give accurate readings. Older or basic testers may only support standard wet-cell — testing an AGM or gel battery on a standard-only tester gives misleading results. Always check the supported battery types on the tester product page; for mixed-fleet workshops where modern AGM and EFB start-stop batteries are common, a multi-chemistry tester is essential.

New batteries take a few charge-discharge cycles to reach their full rated CCA — a fresh-from-the-shelf battery typically tests 10-20% below its rated CCA on first conductance test. This isn't a fault — the battery's plates are still bedding in. Re-test after 1-2 weeks of use; the reading should rise to the rated level. If it stays low, that may indicate a manufacturing defect — return under warranty with the test printout.

Many modern testers are dual-voltage 12V/24V — covering car/van/light-commercial up to HGV and plant batteries from a single unit. For 24V plant and HGV systems with two 12V batteries in series, the tester typically tests each battery individually after disconnection of the series link — most testers show this in the user manual. Check the supported voltage range on the tester product page; for mixed-fleet operations covering both 12V and 24V, a dual-voltage tester is standard.

Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.

Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and 'Check where we deliver' confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa.
