The Renogy Deep Cycle AGM Battery features an integrated internal structure and sealed design, sparing you from intricate internal troubleshooting. Therefore, the battery is ideal for solar system beginners or anyone who prefers a product with simple operations. The upgraded electrolyte formula ensures excellent discharge performance from -4 to 140°F/ -20 to 60°C, allowing the battery to function seamlessly in freezing conditions without requiring extra temperature compensation. You can connect up to 4 batteries in parallel. You can also connect multiple batteries in series. It's advisable to connect batteries of the same type (AGM), capacity (Ah), and voltage (V) from the same brand. We also recommend using a battery balancer to prolong the service life when connecting multiple batteries in series and/or parallel. Before installing the battery, please note that you need to leave 1.97-3.94 in (5-10 cm) for the top of the battery; the side with busbars needs to be left at least 7.87 in (20 cm).
Q: what is the warranty on this battery? Renogy - Deep Cycle AGM Battery 12 Volt 100Ah
A: Hi, Thank you for your inquiry regarding the warranty for the Renogy 12V 100Ah Deep Cycle AGM Battery. If the battery was purchased directly through the Renogy website account, it is covered by a 2-year prorated material and workmanship warranty. First 12 months: Free replacement if the battery fails due to defects. After 12 months: Prorated replacement cost based on the remaining warranty period. Exclusions: Improper installation, operation, or storage voids the warranty. However, if the battery was purchased through a reseller or a third party, warranty claims must be processed through the original purchaser, as Renogy requires the original order information to verify and approve any warranty request. I hope this information helps! Best regards, Renogy Support Team
A: Hello RiffRaff1. Thank you for your inquiry. You do not need to be concerned about alternator damage during the charging process, provided that a properly rated DC-DC battery charger (such as Renogy’s 20A or 40A models) is used. These chargers are designed to regulate the current from the alternator, ensuring safe and efficient charging without placing excessive strain on the vehicle’s electrical system. Regarding compatibility with a 400-watt solar array, the Renogy 12V 100Ah Deep Cycle AGM Battery is well-suited for this application. A 400W solar setup can typically generate approximately 120 to 160 amp-hours per day, depending on environmental conditions and location. This level of input is compatible with a single 100Ah battery, though a larger battery bank may be advisable for extended autonomy or heavier power demands. We hope this information helps!
