Tudor Endurance + PRO GEL Batteries

Tudor Endurance+PRO GEL: true deep cycle for intensive use

A deep-cycle GEL battery works the opposite way to a starter battery: instead of delivering a huge current for seconds, it supplies moderate power for hours and accepts deep discharges day after day. The Tudor Endurance+PRO GEL range immobilises the electrolyte as gel, which prevents leaks and stratification, needs no maintenance and withstands over 1,000 cycles at 50% depth of discharge (DoD) — its benchmark for heavy-duty service.

Models and uses in the Endurance+PRO GEL range

• Tudor TG60 (60 Ah): GEL battery for small caravans and auxiliary equipment.
• Tudor TG100 (100 Ah): the most popular GEL leisure battery for mid-size motorhomes.
• Tudor TG140 (140 Ah): large motorhomes running a fridge, heating and an inverter.
• Tudor TG180 (180 Ah): premium RVs and boats with high on-board consumption.

It is also a frequent pick as a golf cart GEL battery and for light electric vehicles recharged overnight.

Frequently asked questions about Tudor GEL batteries

What is the difference between a GEL and an AGM battery?

Both are sealed and maintenance-free, but GEL withstands more deep-discharge cycles and longer discharges, while AGM delivers higher current peaks. For a motorhome in daily use, the Tudor GEL is the longer-lasting option.

How many cycles does a Tudor Endurance+PRO GEL last?

Over 1,000 cycles at 50% depth of discharge (DoD). If you keep your usual discharge below 50%, the cycle count increases.

Can a GEL battery start an engine?

That is not its job: the Endurance+PRO GEL is a deep-cycle service battery. Keep the vehicle starter battery for cranking and use the GEL for the habitation area, equipment and on-board loads.

Which GEL battery do I need for my motorhome?

As a guide within the range: TG60 for a small caravan, TG100 for a mid-size motorhome, TG140 for a large motorhome and TG180 for a premium RV or boat.
