3kWh Deep Cycle Batteries

Available specifications and prices

Prices are in Saudi riyals as shown on the product pages, and specifications are taken from the product data itself.

Expected runtime

Formula: usable energy divided by load. Figures are estimates and drop 10-15% in high heat or at high discharge current.

Advantages

• Built for repeated cycling, not only cranking
• Economical option for backup systems
• Available at 100Ah, 150Ah and 200Ah

Points to consider

• Usable energy is roughly half of nameplate (50% DoD)
• Shorter cycle life that falls quickly with heat
• Heavier and bulkier per kWh
• Needs periodic full charging to avoid sulphation

Installation and usage considerations

Install in a ventilated spot out of direct sun, avoid discharging below 50%, and check each battery's voltage periodically - imbalance in a lead-acid bank destroys the whole bank.

Use cable sized for the current with a short run between bank and inverter, plus a breaker or fuse on the positive terminal. Thin cable and long runs are the number-one cause of poor performance wrongly blamed on the battery.

How to pick the right option

Start from daily kWh and the hours you need, then divide by allowed depth of discharge (0.9 lithium, 0.5 gel) to get required nameplate capacity.

Fix the system voltage from your inverter, then compare options on price per usable kWh rather than price per unit.
