Sinetech (Pty) Ltd. warrants its full range of products against defects in workmanship and materials, fair wear and tear accepted, for a period of 1 (one) year from the date of delivery/collection for all equipment, with the exception of PV solar panels, or other products, which may carry a different warranty if specified by Sinetech as per relevant quotations. Warranties specified in manufacturer’s manuals are not Sinetech warranties and may not apply in South Africa and should not be taken as the warranty offered by Sinetech. Warranties are based on a bring-in-basis where the equipment is of a size that it can be brought into Sinetech’s workshop. Where the size and installation of the product makes it impractical to bring-in to our workshops, Sinetech (Pty) Ltd. reserves the right to charge for travel time and kilometers travelled to and from the site where the product is installed. During this warranty year period, Sinetech (Pty) Ltd. will, at its own discretion, repair or replace the defective product free of charge. This warranty will be considered void if the unit has suffered any physical damage or alteration, either internally or externally, and does not cover damages arising from improper use such as, but not exclusive to:

  • Reverse of battery polarity
  • Inadequate or incorrect connection of the product and/or of its accessories
  • Mechanical shock or deformation
  • Contact with liquid or oxidation by condensation
  • Use in an inappropriate environment (dust, corrosive vapour, humidity, high temperature, biological infestation.)
  • Breakage or damage due to lightning, surges, spikes or other electrical occurrences
  • Connection terminals and screws destroyed or other damage such as overheating due to insufficient tightening of terminals
  • When considering any electronic breakage except due to lightning, reverse polarity, over-voltage, etc. the state of the internal control circuitry determines the warranty

This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone else than Sinetech (Pty) Ltd. or one of its authorised Qualified Service Partners. In order to qualify for the warranty, the product must not be disassembled or modified. Repair or replacement are our sole remedies and Sinetech (Pty) Ltd. shall not be liable for damages, whether direct, incidental, special, or consequential, even caused by negligence or fault. Sinetech (Pty) Ltd. owns all parts removed from repaired products. Sinetech (Pty) Ltd. uses new or re-conditioned parts made by various manufacturers in performing warranty repairs and building replacement products. If Sinetech (Pty) Ltd. repairs or replaces a part of a product, its warranty term is not extended. The repair itself will carry a three month warranty. Removal of serial nos. may void the warranty.

How to Handle and Store Batteries – ensure the battery is fully charged before storage

It is imperative to refer to the battery manufacturers specifications and recommendations. Open flames or sparks can cause explosions!
Batteries should be stored in a cool, dry (20-25°C) place and out of direct sunlight. Tilting a semi-sealed battery can cause acid to leak through the over pressure relief vents. Batteries must always be transported and stored in an upright position. Under no circumstances should any tools or objects be placed on top of a battery. All battery connections must be carried out with appropriate and preferably isolated tools! No battery should be stored in a discharged or partly discharged condition as this will damage the battery. When storing a battery for long periods of time, check the voltage every 3 – 6 months. If the voltage (OCV) drops below 12.5V, recharge the battery. Check the hydrometer periodically. If indicators appear black, recharge the battery immediately even if the storage period has been less than 3 – 6 months. Do not discard any battery but return to nearest recycling depot for proper handling and de-commissioning. Remember that batteries can be extremely dangerous if handled incorrectly !
