Never cut a dive short due to a dead light. The DIVEVOLK Spare Battery for the SL20 Dive Light uses a high-capacity 21700 lithium cell — the same cell format used in the SL20 — so you always have a fully charged replacement ready to swap before your second dive. Simply pre-charge the spare, swap it out at the surface, and you are ready to go without waiting for a full recharge cycle.
Designed as an exact replacement for the SL20, it maintains the same output performance and burn time as the original. Essential for multi-dive days, liveaboards, or any session where you need your lights running at full power from start to finish.

In-stock orders are usually processed the same working day. If an item isn’t on the shelf, we replenish it — typically within 2–4 days — and send your order out the moment it arrives.
Made-to-order gear, such as certain Nauticam ports and extensions, takes longer — we’ll confirm the lead time with you before you commit.
Need it urgently? Tell us before you place the order and we’ll be honest about what we can commit to.
We don’t sit on orders. If something unforeseen slows yours down — a stock gap, a courier hiccup — we’ll tell you early and do our best to put it right.
We ship within Singapore by courier and worldwide via tracked international services. Import duties and local taxes are the responsibility of the recipient.
