Mining battery chargers — because batteries die in charging bays, not on machines
Ask any mine electrician where battery life is really decided and he will point at the charging bay. That is why Microtex supplies its underground packs as a system: mining-duty chargers matched to the battery, running the charge profile our own engineers proved on our own cells — with records the mine can audit.
Profile-controlled charging — Stratification managed by design — Auditable Ah & time logs — Battery + charger, one responsibility

What a mining charger must do differently
Finish clean. A charging bay’s ventilation is budgeted, so the charge must complete without needless gassing — the profile holds each stage to the battery’s actual needs instead of force-feeding it. Stir deliberately. Tall cells stratify; our charge includes a calculated mixing stage that manages electrolyte stratification without cooking the battery. Refuse to run away. Supervision and trip logic — including a hard limit on total charging time — stand guard against the faults that quietly murder batteries on night shift. Write everything down. Ampere-hours returned and charging time are metered and logged, downloadable for the mine’s records — so battery discipline becomes auditable fact, not folklore.
Matched, not merely compatible
These chargers run the charging canon developed and trial-proven by Microtex engineering for our own tubular mining cells — voltage stages, change-over currents and temperature behaviour set for the battery they feed, commissioned at your site with the profile locked against casual adjustment. One supplier for pack and charger means one warranty conversation and nowhere for blame to hide — the same philosophy as everything on our engineering page.
The WAFADAR mark
Microtex mining chargers carry the WAFADAR mark — the word means faithful, and in a charging bay that is the entire job description. Each unit is finished in the LIMITLESS range’s flame-retardant safety yellow, built in an IP-rated enclosure for mining-site conditions, and carries a rating plate that states its accountability plainly: marketed and serviced by Microtex Energy Private Limited, 42, Second Main, Second Phase, Peenya Industrial Area, Bengaluru 560058, India. One mark on the charger, one company answerable for battery and charger together.
Questions mine electrical engineers ask us
Will your charger work with our existing battery fleet?
Usually, yes — the profile is engineered to the battery, so send the fleet’s battery details (voltage, capacity, type, age) and the bay’s supply particulars. Where an existing fleet’s batteries are ours already, matching is immediate.
What supply does the charging bay need?
Chargers are built to the mine’s actual supply — state voltage, phases and frequency in the enquiry and the specification is engineered to it, with the bay requirements (clearances, ventilation expectations, cable routes) documented for your planning.
Can operators change the charge settings?
No — deliberately. Operators get start, stop, and honest indications; the profile lives behind protected access for service engineers. Most warranty disputes begin with a well-meaning adjustment; this design removes the temptation.
What about equalising charges?
The profile’s mixing stage does much of an equalise’s traditional work every cycle. Where the duty still warrants periodic equalisation, the regime is specified with the installation — engineered, scheduled, and logged like everything else.
