Warranty terms and what the rules cover
Local rules on batteries are thin. A South African installer guide notes that there are limited regulations and documentation on battery storage installation, so ask the seller in writing which standard the installation follows. Most of the regulations cited for batteries are written for backup power, meaning UPS units. Warranties differ widely: listings show 6 months for batteries built for frequent cycling, and 10-year warranties on some lithium modules, where 24 months is the standard manufacturer's cover. Compare the warranty term, the cycle limit and what it covers.
Lifespan and the seasons
Modern lithium (LiFePO4) batteries are listed in South Africa as lasting 10 to 15 years and 6,000 to 8,000 charge cycles. Summer runs from December to February and winter from June to August. Size the battery for the longest outage or the heaviest load you expect, not the average day, and plan the purchase before the season you need it.
How prices are quoted and delivered
Listings give the price in rand and the capacity in mAh, Wh or kWh, and the voltage (12 V, 24 V or 48 V). Compare the price per watt-hour rather than the sticker price. Heavier units, such as the 5 to 10 kWh lithium batteries, need delivery planning, so ask whether delivery to your city, such as Johannesburg, Cape Town, Durban, Pretoria or Gqeberha, is included in the price.
What to put in your request
Say what the battery must run, such as a router, a fridge or a house circuit, and the capacity or runtime you need. Give the voltage, the quantity, whether you need a battery management system (BMS), and any make you prefer. Add the warranty you require, the delivery city and your budget in rand.
