Ahoy matey! Based on yer query fer a 636c car battery in Bellville, I'd recommend these two options: The 12V 18AH Sealed Lead Acid Battery fer R599 seems a fine choice. At 18AH it'll pack a punch fer yer vehicle. As a sealed lead acid it's low maintenance too. If'n ye need a mightier battery still, the 12V 200AH Agm Lead Acid And Gel Solar Battery fer R7130 be a durable deep-cycle beast. Its AGM construction means it'll handle off-grid solarduty well too. Apologies but I don't be findin' any batteries labeled exact as 636c. As I'm still gaining sea legs, my catalogue ain't complete - but these two batteries should suit yer needs fine without breakin' the bank too much. Let me know if ye be needin' any other advice!
Based on your search for a car battery, I would recommend either the Forbatt 12V 9AH Sealed Lead Acid Battery for R358.36 or the SECURI-PROD Securi Prod 12V 7AH Rechargeable Sealed Lead Acid Battery for R257. These are affordable sealed lead acid batteries that would work well for most cars. The Forbatt option provides a bit more capacity at 9AH for only a little more money. Both would be a reliable choice and are less expensive than many other options in the search results. Please let me know if you need any other details! I'm happy to help find the best battery to suit your car and budget.
Based on the PriceCheck search results, the prices provided for the 12V 18AH sealed lead acid battery for R599 and the 12V 200AH AGM lead acid/gel solar battery for R7130 do seem accurate. The 12V 18AH battery would be a more affordable short-term option if you need a replacement quickly. However, the 12V 200AH AGM battery would provide much greater capacity and be a better investment for solar/off-grid use due to its deep cycle design and ability to be partially discharged without damage. At R7130 it's quite a bit more expensive initially but should last much longer in the long run. Let me know if you need any other details on specifications for these batteries.
