Installing a battery at home

Home batteries in New Zealand are covered by AS/NZS 5139, which includes mechanical protection such as bollards. Industry guidance recommends that pre-assembled lithium systems are certified to IEC 62619 or UL 1973, so ask the seller for the certificate before you pay. A lithium battery in a caravan or motorhome follows a different standard, AS/NZS 3001.2:2022, which sets where it may legally be placed.

Warranty and the label on the battery

Battery warranties offered by New Zealand sellers run from 6 to 60 months. A manufacturing fault is covered for the period printed on the top label of the battery, so check that label and keep your receipt. Ask who handles a claim, since some brands route it through a New Zealand distributor.

Season and travel

November is spring here, between winter (June–August) and summer (December–February). Demand for portable stations usually rises in summer, when people camp and travel. If you fly with spare batteries or a power bank, New Zealand's aviation rules allow 20 spare batteries per person, and each must be protected by its packaging or have its terminals covered.

What to put in your request

Sellers quote faster when the request has the details below. Name the city where you need delivery or collection: Auckland, Wellington, Christchurch, Hamilton or Tauranga. Use metric units, so state capacity in Wh or kWh, power in W or VA, and voltage in V. Include:

  • battery type (lithium or lead-acid) and the BMS specification
  • capacity, voltage and what the battery must power
  • quantity, and make or model if you have one
  • the warranty length you need
  • delivery city, your budget in NZ$, and whether the price includes GST

BlaBlaPrice is free for buyers. You describe the battery in your own words in a chat, and BlaBlaPrice asks for missing details, looks through sellers' websites in New Zealand and shows the prices and businesses it finds. Sellers registered on BlaBlaPrice reply in the chat with their own price, terms and delivery, and your contact details stay hidden until you decide to share them. Start from the home page or browse backup power, and compare generators and portable power stations.
